Electrocardiogram (ECG) illustration showing the atrial vulnerable period. This period is equivalent to the descending branch of the R wave, and the ventricular vulnerable period is equivalent to about 30 milliseconds before and after the T wave peak. Stimulation during the vulnerable period, whether external electrical stimulation or spontaneous premature contraction of the heart, will induce fibrillation. | |
