Abstract

ST-segment alternans indicates nonuniformity of ventricular repolarization in time and space, and consequently correlates with the occurrence of ventricular fibrillation during cardiac ischemia.^1,2 ST alternans has been observed during spontaneous and induced myocardial ischemia in experimental animals^1,3 and in man during exercise,⁴ Prinzmetal angina^5,6 and coronary angioplasty.^7-9 Whereas ST-segment shifts (particularly ST-segment elevation) are frequent during angioplasty,¹⁰ ST-segment alternans is infrequent. We present a patient who on sequential balloon inflations during coronary angioplasty demonstrated a sequence of ST-segment shifts recorded by intracoronary electrocardiography, reflecting the unique effects of repeated short episodes of ischemia on the alternans phenomenon.
