Abstract: Key Teaching Points•A wearable cardioverter-defibrillator (WCD) has the capability to serve as a continuous cardiac monitoring device for ventricular tachyarrhythmia detection/treatment in high-risk patients within the vulnerable period after acute myocardial injury or revascularization/cardiac surgery and potentially could also monitor for significant pauses in patients with conduction system disease.•Current criteria for detecting asystole events in patients with WCD will miss a considerable number of patients with significant asystole episodes that do not meet the existing criteria of a fall in electrocardiogram input signal below 100 microvolts for at least 16 seconds.•Alert features for asystole events need to be turned on, but also required are improvements in WCD design and in the detection algorithms discriminating artifacts and real events. Improved sensing electrode contact with skin would improve the utility of the system to accurately identify long pauses in rhythm in those with underlying conduction system disease. •A wearable cardioverter-defibrillator (WCD) has the capability to serve as a continuous cardiac monitoring device for ventricular tachyarrhythmia detection/treatment in high-risk patients within the vulnerable period after acute myocardial injury or revascularization/cardiac surgery and potentially could also monitor for significant pauses in patients with conduction system disease.•Current criteria for detecting asystole events in patients with WCD will miss a considerable number of patients with significant asystole episodes that do not meet the existing criteria of a fall in electrocardiogram input signal below 100 microvolts for at least 16 seconds.•Alert features for asystole events need to be turned on, but also required are improvements in WCD design and in the detection algorithms discriminating artifacts and real events.
