[Silent ischemia in long-term ECG in the early post-infarct period].
101 consecutive patients (73 m, 29 f; 48 AMI, 53 IMI) under 70 years were assigned to 24 hour-Holter monitoring in the third week after first transmural infarction. ST-segment analysis could be performed in 88 patients (89%). 18 patients (20%) had episodes of ischemia which were silent in 95%. One third of these episodes occurred in the absence of physical exercise. Ischemic events displayed a circadian rhythm with a maximum between 6 and 12 a.m. There was no correlation between ischemia and the occurrence of ventricular arrhythmia. In addition, we show that visual control of automatic ST-segment analysis is a prerequisite for routine use in clinical practice.
