Prinzmetal's angina. Aternating ST-segment deviation in anterior and inferior electrocardiographic leads during the same episode of pain.
A 60-year-old man had recurrent episodes of spontaneously occurring pain in the chest which were associated with ST-segment elevation consistent with Prinzmetal's angina. The simultaneous elevation of the S-T segment in anterior and inferior electrocardiographic leads with initial ST-segment depression followed by elevation in high lateral leads suggested that heightened vascular reactivity in variant angina may involve multiple coronary vessels during the same episode of vasospasm.
