Repetitive ventricular fibrillation preceded by both ST segment depression and elevation during acute myocardial ischemia.
A patient had repetitive ventricular fibrillation preceded by alternating ST segment depression and elevation. The ECG changes were confined to the precordial leads only, reflecting subendocardial and transmural ischemia, respectively. It is speculated that the patient exhibited consecutive episodes of subtotal and total coronary occlusion, both episodes being critical enough to induce lethal arrhythmias.
