FAQ
Frequently Asked Questions
No. While both use electricity, cardioversion is a planned, lower-energy shock synchronized with a specific point in the heartbeat. Defibrillation is an emergency, high-energy, unsynchronized shock for life-threatening rhythms like ventricular fibrillation.
Patients are almost always sedated or under brief general anesthesia for the procedure, so they do not feel pain or remember it.
Success rates are high initially (often over 90% for certain rhythms like atrial flutter), but the abnormal rhythm may return over time, requiring medication or further procedures.
Electrical cardioversion uses an electric shock delivered via pads on the chest. Chemical (or pharmacological) cardioversion uses intravenous medications to try to restore normal rhythm.
