This can cause life-threatening complications, such as a stroke or a blood clot traveling to your lungs. If necessary, your doctor may prescribe blood-thinning medications before the procedure or will check for blood clots in your heart before cardioversion.

Cardioversion can be done during pregnancy, but it's recommended that the baby's heartbeat be monitored during the procedure. Cardioversion procedures are usually scheduled in advance.

However, if your symptoms are severe, you may need to have cardioversion in an emergency setting. You typically can't eat or drink anything for about eight hours before your procedure.

Your doctor will tell you whether to take any of your regular medications before your procedure. If you do take medications before your procedure, sip only enough water to swallow your pills.

Before cardioversion, you may have a procedure called a transesophageal echocardiogram to check for blood clots in your heart.

Blood clots can break free by cardioversion, causing life-threatening complications. Your doctor will decide whether you need a transesophageal echocardiogram before cardioversion.

If your doctor finds blood clots, your cardioversion procedure will be delayed for three to four weeks. During that time, you'll take blood-thinning medications to reduce your risk of complications.

You'll be given medications through an IV to make you sleep during the procedure so that you won't feel any pain from the shocks.

You may receive other medications through the IV to help restore your heart rhythm. A nurse or technician places several large patches called electrodes on your chest.

The electrodes connect to a cardioversion machine defibrillator using wires. The machine records your heart rhythm and delivers shocks to your heart to restore a normal heart rhythm.

This machine can also correct your heart's rhythm if it beats too slowly after cardioversion. Electric cardioversion is done on an outpatient basis, meaning you can go home the same day your procedure is done.

You'll spend an hour or so in a recovery room being closely monitored for complications. You'll need someone to drive you home, and your ability to make decisions may be affected for several hours after your procedure.

Even if no clots were found in your heart before your procedure, you'll take blood-thinning medications for at least several weeks after your procedure to prevent new clots from forming.

With a heart attack, caused by blockage of the arteries, the victim feels severe chest pains but almost always remains conscious; however, SCA victims will always lose consciousness.

Researchers state that SCA is the result of a "ventricular fibrillation," a quivering of the heart which prevents the heart muscle from pumping blood to the body.

To overcome this condition, the victim will need various forms of help in order to survive, the most important of which may well be the assistance of a defibrillator.

Those used in hospitals are expensive machines that send voltage through two paddles that a medical professional places on a heart attack victim's chest area.

Automated External Defibrillator's AEDs have become the norm in schools, gymnasiums, city offices, and workout facilities.

Paddles are reusable, being cleaned after use and stored for the next patient. Gel is therefore not preapplied, and must be added before these paddles are used on the patient.

Paddles are generally only found on manual external units. Newer types of resuscitation electrodes are designed as an adhesive pad, which includes either solid or wet gel.

These are peeled off their backing and applied to the patient's chest when deemed necessary, much the same as any other sticker.

The electrodes are then connected to a defibrillator, much as the paddles would be. If defibrillation is required, the machine is charged, and the shock is delivered, without any need to apply any additional gel or to retrieve and place any paddles.

Most adhesive electrodes are designed to be used not only for defibrillation, but also for transcutaneous pacing and synchronized electrical cardioversion.

These adhesive pads are found on most automated and semi-automated units and are replacing paddles entirely in non-hospital settings.

In hospital, for cases where cardiac arrest is likely to occur but has not yet , self-adhesive pads may be placed prophylactically.

Pads also offer an advantage to the untrained user, and to medics working in the sub-optimal conditions of the field. Pads do not require extra leads to be attached for monitoring, and they do not require any force to be applied as the shock is delivered.

Thus, adhesive electrodes minimize the risk of the operator coming into physical and thus electrical contact with the patient as the shock is delivered by allowing the operator to be up to several feet away.

The risk of electrical shock to others remains unchanged, as does that of shock due to operator misuse. Self-adhesive electrodes are single-use only.

They may be used for multiple shocks in a single course of treatment, but are replaced if or in case the patient recovers then reenters cardiac arrest.

Resuscitation electrodes are placed according to one of two schemes. The anterior-posterior scheme is the preferred scheme for long-term electrode placement.

One electrode is placed over the left precordium the lower part of the chest, in front of the heart.

The other electrode is placed on the back, behind the heart in the region between the scapula. This placement is preferred because it is best for non-invasive pacing.

The anterior-apex scheme can be used when the anterior-posterior scheme is inconvenient or unnecessary. In this scheme, the anterior electrode is placed on the right, below the clavicle.

The apex electrode is applied to the left side of the patient, just below and to the left of the pectoral muscle.

This scheme works well for defibrillation and cardioversion, as well as for monitoring an ECG. Researchers have created a software modeling system capable of mapping an individual's chest and determining the best position for an external or internal cardiac defibrillator.

The exact mechanism of defibrillation is not well understood. They discovered that small electrical shocks could induce ventricular fibrillation in dogs, and that larger charges would reverse the condition.

In , Dr. Henry Hyman, an electrical engineer, looking for an alternative to injecting powerful drugs directly into the heart, came up with an invention that used an electrical shock in place of drug injection.

This invention was called the Hyman Otor where a hollow needle is used to pass an insulated wire to the heart area to deliver the electrical shock.

The hollow steel needle acted as one end of the circuit and the tip of the insulated wire the other end. Whether the Hyman Otor was a success is unknown.

The external defibrillator as known today was invented by Electrical Engineer William Kouwenhoven in William studied the relation between the electric shocks and its effects on human heart when he was a student at Johns Hopkins University School of Engineering.

His studies helped him to invent a device for external jump start of the heart. Beck's theory was that ventricular fibrillation often occurred in hearts which were fundamentally healthy, in his terms "Hearts that are too good to die", and that there must be a way of saving them.

Beck first used the technique successfully on a year-old boy who was being operated on for a congenital chest defect. The boy's chest was surgically opened, and manual cardiac massage was undertaken for 45 minutes until the arrival of the defibrillator.

Beck used internal paddles on either side of the heart, along with procainamide , an antiarrhythmic drug, and achieved return of a perfusing cardiac rhythm.

These early defibrillators used the alternating current from a power socket, transformed from the — volts available in the line, up to between and volts, to the exposed heart by way of "paddle" type electrodes.

The technique was often ineffective in reverting VF while morphological studies showed damage to the cells of the heart muscle post mortem.

The nature of the AC machine with a large transformer also made these units very hard to transport, and they tended to be large units on wheels.

Until the early s, defibrillation of the heart was possible only when the chest cavity was open during surgery. The closed-chest defibrillator device which applied an alternating voltage of greater than volts, conducted by means of externally applied electrodes through the chest cage to the heart, was pioneered by Dr V.

Eskin with assistance by A. Early successful experiments of successful defibrillation by the discharge of a capacitor performed on animals were reported by N.

Gurvich and G. Yunyev in It is described in detail in Gurvich's book, Heart Fibrillation and Defibrillation. The first Czechoslovak "universal defibrillator Prema" was manufactured in by the company Prema, designed by dr.

In his device was awarded Grand Prix at Expo In , US senator Hubert H. Humphrey visited Nikita Khrushchev and among other things he visited the Moscow Institute of Reanimatology, where, among others, he met with Gurvich.

At the same time, Humphrey worked on establishing of a federal program in the National Institute of Health in physiology and medicine, telling to the Congress: "Let's compete with U.

This team further developed an understanding of the optimal timing of shock delivery in the cardiac cycle, enabling the application of the device to arrhythmias such as atrial fibrillation , atrial flutter , and supraventricular tachycardias in the technique known as " cardioversion ".

The Lown-Berkovits waveform, as it was known, was the standard for defibrillation until the late s. Earlier in the s, the "MU lab" at the University of Missouri had pioneered numerous studies introducing a new waveform called a biphasic truncated waveform BTE.

In this waveform an exponentially decaying DC voltage is reversed in polarity about halfway through the shock time, then continues to decay for some time after which the voltage is cut off, or truncated.

The studies showed that the biphasic truncated waveform could be more efficacious while requiring the delivery of lower levels of energy to produce defibrillation.

The BTE waveform, combined with automatic measurement of transthoracic impedance is the basis for modern defibrillators [ citation needed ].

A major breakthrough was the introduction of portable defibrillators used out of the hospital. Frank Pantridge in Belfast.

Today portable defibrillators are among the many very important tools carried by ambulances. They are the only proven way to resuscitate a person who has had a cardiac arrest unwitnessed by Emergency Medical Services EMS who is still in persistent ventricular fibrillation or ventricular tachycardia at the arrival of pre-hospital providers.

Gradual improvements in the design of defibrillators, partly based on the work developing implanted versions see below , have led to the availability of Automated External Defibrillators.

These devices can analyse the heart rhythm by themselves, diagnose the shockable rhythms, and charge to treat.

This means that no clinical skill is required in their use, allowing lay people to respond to emergencies effectively.

Until the mid 90s, external defibrillators delivered a Lown type waveform see Bernard Lown which was a heavily damped sinusoidal impulse having a mainly uniphasic characteristic.

Biphasic defibrillation alternates the direction of the pulses, completing one cycle in approximately 12 milliseconds. Biphasic defibrillation was originally developed and used for implantable cardioverter-defibrillators.

When applied to external defibrillators, biphasic defibrillation significantly decreases the energy level necessary for successful defibrillation, decreasing the risk of burns and myocardial damage.

A further development in defibrillation came with the invention of the implantable device, known as an implantable cardioverter-defibrillator or ICD.

Similar developmental work was carried out by Schuder and colleagues at the University of Missouri. The work was commenced, despite doubts amongst leading experts in the field of arrhythmias and sudden death.

There was doubt that their ideas would ever become a clinical reality. In Bernard Lown introduced the external DC defibrillator.

This device applied a direct current from a discharging capacitor through the chest wall into the heart to stop heart fibrillation.

In fact, the implanted defibrillator system represents an imperfect solution in search of a plausible and practical application. The problems to be overcome were the design of a system which would allow detection of ventricular fibrillation or ventricular tachycardia.

Despite the lack of financial backing and grants, they persisted and the first device was implanted in February at Johns Hopkins Hospital by Dr.

Levi Watkins , Jr. Modern ICDs do not require a thoracotomy and possess pacing , cardioversion, and defibrillation capabilities.

The invention of implantable units is invaluable to some regular sufferers of heart problems, although they are generally only given to those people who have already had a cardiac episode.

People can live long normal lives with the devices. Many patients have multiple implants. A patient in Houston, Texas had an implant at the age of 18 in by the recent Dr.

Antonio Pacifico. He was awarded "Youngest Patient with Defibrillator" in Though today these devices are implanted into small babies shortly after birth.

As devices that can quickly produce dramatic improvements in patient health, defibrillators are often depicted in movies, television, video games and other fictional media.

Their function, however, is often exaggerated, with the defibrillator inducing a sudden, violent jerk or convulsion by the patient; in reality, although the muscles may contract, such dramatic patient presentation is rare.

Similarly, medical providers are often depicted defibrillating patients with a "flat-line" ECG rhythm also known as asystole.

This is not normal medical practice, as the heart cannot be restarted by the defibrillator itself. Only the cardiac arrest rhythms ventricular fibrillation and pulseless ventricular tachycardia are normally defibrillated.

The purpose of defibrillation is to depolarize the entire heart all at once so that it is synchronized, effectively inducing temporary asystole, in the hope that in the absence of the previous abnormal electrical activity, the heart will spontaneously resume beating normally.

Someone who is already in asystole cannot be helped by electrical means, and usually needs urgent CPR and intravenous medication.

A useful analogy to remember is to think of defibrillators as power cycling, rather than jump-starting, the heart. There are also several heart rhythms that can be "shocked" when the patient is not in cardiac arrest, such as supraventricular tachycardia and ventricular tachycardia that produces a pulse ; this more-complicated procedure is known as cardioversion , not defibrillation.

In Australia up until the s it was relatively rare for ambulances to carry defibrillators. This changed in after Australian media mogul Kerry Packer had a heart attack and, purely by chance, the ambulance that responded to the call carried a defibrillator.

After recovering, Kerry Packer donated a large sum to the Ambulance Service of New South Wales in order that all ambulances in New South Wales should be fitted with a personal defibrillator, which is why defibrillators in Australia are sometimes colloquially called "Packer Whackers".

These valuable tools are automated and offer voice assistance to aid a volunteer in successfully using them.
