This medical procedure is generally used when emergency care is needed for a rapid heart rate, such as that seen with sustained ventricular tachycardia. Cardioversion sends electric shocks to the heart through sensors (electrodes) placed on the chest. The shock affects the heart's electrical signals and restores a regular heartbeat.

Very tired Cardioversion also treats other kinds of abnormal heartbeats, including atrial flutter, atrial tachycardia and ventricular tachycardia. Cardioversion or defibrillation is also used in emergency situations for people who suffer sudden life threatening arrhythmias.

A very fast heartbeat Short of breath Very tired Cardioversion also treats other kinds of abnormal heartbeats, including atrial flutter, atrial tachycardia and ventricular tachycardia. Cardioversion or defibrillation is also used in emergency situations for people who suffer sudden life threatening arrhythmias.
If you have atrial fibrillation, blood clots can form in your heart’s left atrium. Cardioversion may knock loose a blood clot in your left atrium. If the clot (embolus) travels to your brain, it can cause a stroke. To avoid this, your doctor may give you medicine (such as warfarin) to make your blood less likely to form blood clots.
External cardioversion Synchronized electrical cardioversion may also be used to treat stable ventricular tachycardia (VT, vtach) that does not respond to a trial of intravenous medications. It is also recommended for the treatment of the following arrhythmias : Supraventricular tachycardia (SVT) due to reentry.
Ventricular tachycardia (v-tach) typically responds well to defibrillation. This rhythm usually appears on the monitor as a wide, regular, and very rapid rhythm. Ventricular tachycardia is a poorly perfusing rhythm; patients may present with or without a pulse.
If you have ventricular tachycardia, you may be given medications called anti-arrhythmics by mouth or IV to slow the fast heart rate. Other heart medications, such as calcium channel blockers and beta blockers, may be prescribed with anti-arrhythmic drugs.
MECHANISM OF CARDIOVERSION The depolarization of the myocardium is followed by a period of refractoriness that has the effect of interrupting the reentrant circuit, thereby breaking the repeating cycle and terminating the arrhythmia.
Defibrillation or unsynchronized cardioversion is indicated in any patient with pulseless VT/VF or unstable polymorphic VT, where synchronized cardioversion is not possible. Synchronized cardioversion is utilized for the treatment of persistent unstable tachyarrhythmia in patients without loss of pulse.
Cardioversion is a procedure used to return an abnormal heartbeat to a normal rhythm. This procedure is used when the heart is beating very fast or irregular. This is called an arrhythmia.
Otherwise, immediate cardioversion is recommended, preferably with a biphasic DC shock of 200 joules. In those in cardiac arrest due to ventricular tachycardia, cardiopulmonary resuscitation (CPR) and defibrillation is recommended....Ventricular tachycardiaFrequency~7% of people in cardiac arrest12 more rows
Patients with pulseless ventricular tachycardia are treated the same as those with ventricular fibrillation, meaning they require immediate cardiopulmonary resuscitation (CPR) and defibrillation. Once the rhythm converts, the patient will need an infusion of amiodarone or lidocaine.
Medical treatment of pulseless VT usually is carried out along with defibrillation and includes intravenous vasopressors and antiarrhythmic drugs. 1 mg of epinephrine IV should be given every 3 to 5 minutes. Epinephrine can be replaced by vasopressin given 40 units IV once.
After the procedure, you may have redness, like a sunburn, where the patches were. The medicines you got to make you sleepy may make you feel drowsy for the rest of the day. Your doctor may have you take medicines to help the heart beat normally and to prevent blood clots.
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs.
Electrical cardioversion is more than 90% effective, though many have AFib again shortly after having it. Taking an antiarrhythmic drug before the procedure can prevent this.
