No life-threatening complications occurred in exercise-testing in 384 938 athletes. Among 1 356 168 patients the most frequent complication was ventricular fibrillation (1:15 000). The step test was associated with a two-fold diminution of fibrillations when compared to bicycle ergometry in the supine position and with a four-fold decrease when compared to conventional bicycle ergometry. Pulmonary oedema, a typical complication, occurred once in 29 000 bicycle ergometries in supine position. Infarctions were seen 3.5 times more frequently between 1950 and 1977 (1:26 000) than in the following four years (1:92 000). Fatal cardiac infarction occurred in 1:42 000 before 1978 and in 1:644 000 thereafter. It was the sole cause of death. Present data show a potentially life-threatening risk of 1:9000 ergometries in patients. Considering the favourable trend at present, a risk of 1:12 000 can be expected in conditions of an experienced investigator. Defibrillation facilities ready for use must be available in any ergometry.
在384938名运动员进行运动测试期间，未发生危及生命的并发症。在1356168名患者中，最常见的并发症是心室颤动（发生率为1:15000）。与仰卧位自行车测力计测试相比，阶梯试验导致的心室颤动发生率降低了两倍，与传统自行车测力计测试相比降低了四倍。肺水肿是一种典型并发症，在仰卧位自行车测力计测试中，每29000次测试发生一例。1950年至1977年期间，心肌梗死的发生率（1:26000）是随后四年（1:92000）的3.5倍。1978年前，致命性心肌梗死的发生率为1:42000，之后为1:644000。这是唯一的死亡原因。目前的数据显示，患者进行测力计测试时存在1:9000的潜在危及生命风险。考虑到目前的良好趋势，在经验丰富的研究人员操作的情况下，预计风险为1:12000。任何测力计测试场所都必须配备随时可用的除颤设备。
