Abstract:
The 5-mV safe voltage limit that has been proposed for hospital safety codes is shown to be based on incorrect assumptions. The actual voltage threshold for 60-Hz current is of the order of 100 mV or greater, because of the effects of electrode interface impedance and cell membrane characteristics. AK value of 50 mV is proposed as the safe voltage limit for 60 Hz current for the purposes of safety standards. The medical community is requested to consider this value.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
