Understanding the Mechanism Behind Synchronized Shock The fundamental principle of defibrillator cardioversion hinges on the depolarization of a critical mass of myocardial cells. The synchronized feature is essential for protecting the heart during specific phases of repolarization, minimizing the risk of inducing a lethal rhythm.
Emergency Defibrillator Cardioversion Protocol Steps
Proper electrode placement and energy selection are determined by the device manufacturer and clinical guidelines to optimize efficacy. The decision to proceed is based on the patient's presentation rather than the specific rhythm strip alone.
Unlike defibrillation, which is delivered without synchronization to the cardiac cycle, cardioversion is synchronized to the R-wave of the ECG to avoid inducing ventricular fibrillation during the vulnerable T-wave phase. Sedation is typically administered to minimize discomfort, although in emergency scenarios where the patient is unconscious or critically unstable, sedation may be omitted.

This involves verifying the patient's identity, reviewing the ECG to confirm the arrhythmia, and checking for the presence of a pulse. Other complications include skin burns at the electrode sites, myocardial stunning following the shock, and the potential for thromboembolism, particularly in patients with atrial fibrillation.
