An analysis was made of differences in response to postinfarction exercise testing between patients with subsequent sudden and non-sudden death occurring during a 6-year follow-up period after acute myocardial infarction. In the 21 patients who died suddenly the ST-segment depression appeared earlier during exercise and was greater at the end of exercise than in those 25 patients whose death was not sudden (p-values less than 0.025). The physical working capacity of the sudden death group was insignificantly better and the work was performed with an insignificantly higher heart rate and lower systolic blood pressure than in the other group. The heart rate-blood pressure product during maximal work load was the same in both groups. The T-wave depression and P-terminal force negativity after exercise were greater in the sudden death group than in the non-sudden death group (p-values less than 0.025, less than 0.001, respectively). Ventricular ectopic beats, especially after exercise, were also more common in the sudden death group.
对急性心肌梗死后6年随访期内发生后续猝死和非猝死的患者在梗死后运动试验中的反应差异进行了分析。在21例猝死患者中，运动期间ST段压低出现得更早，且运动结束时比25例非猝死患者更明显（p值小于0.025）。猝死组的体力工作能力略好，与另一组相比，工作时心率略高，收缩压略低。两组在最大工作负荷时的心率-血压乘积相同。运动后猝死组的T波压低和P波终末电势负值比非猝死组更大（p值分别小于0.025、小于0.001）。室性异位搏动，尤其是运动后，在猝死组中也更常见。
