Localizing Infarcts On a 12-Lead EKG

The current through dry skin is therefore 150V / 50,000 ohms, which is .003 A, or 3 mA (milliamps). The current required to produce ventricular fibrillation across an arm-arm or arm-leg circuit is 80mA. Thus, a 3 mA current might cause a localized burn, but could not deliver a high enough current density to the myocardium to cause fibrillation. ................
