本文报道6例冠心病患者在极量运动试验时发生运动性低血压及运动后心室颤动,用电击去颤成功。作者强调了运动试验时观察收缩压变化的重要性,探讨了发生低血压及心室颤动的机理,同时指出运动后心室颤动是少见的,因其中5例系发生于10,751次试验中,发生率为0.047％。方法:运动试验都按Bruce分级法进行,每3分钟增加平板速度及倾斜度,直到受试者出现不能耐受的症状为止。如出现连续
This article reports 6 patients with coronary heart disease during extreme exercise test occurs in patients with exercise-induced hypotension and ventricular fibrillation after tremor, shock tremor with electric shock. The authors emphasize the importance of observing changes in systolic blood pressure during exercise testing, discussing the underlying mechanisms of hypotension and ventricular fibrillation, and point out that ventricular fibrillation after exercise is rare, as 5 of these occurred in 10,751 trials, with a rate of 0.047%. METHODS: Exercise tests were performed using the Bruce staging method with plate speed and slope increased every 3 minutes until the subject developed intolerable symptoms. If there is continuous
