← ScienceWhich outcome results when a cardiac defibrillator's electric field diminishes?
A)Increased ventricular fibrillation susceptibility
B)Ineffective cell membrane depolarization✓
C)Augmented sinoatrial node automaticity
D)Reduced myocardial oxygen consumption
💡 Explanation
Ineffective cell membrane depolarization occurs because electrical defibrillation relies on applying Non-selective myocardial stimulation which establishes uniform electrical potentials across myocardial cells therefore stopping arrhythmias, rather than allowing other possible unintended cardiac changes.
