What is the constant voltage level likely to cause asystole?

Asystole refers to a state of no electrical activity in the heart, which can lead to cardiac arrest. The constant voltage level that poses the highest risk for causing asystole is more than 2 A (amperes). In general, when the current flowing through the body exceeds certain thresholds, it can disrupt normal cardiac function.

The risk of asystole increases significantly with higher current levels, as they can lead to disturbances in the heart's electrical conduction system. Values greater than 2 A can overwhelm the heart's tissues, potentially leading to failure of the electrical activity required for the heart to beat effectively. Current levels at this magnitude can lead to significant damage or failure of the myocardium, thereby resulting in asystole.
