【摘要】 对46例冠心病患者24h不同时相的动态心电图的心率、心律、ST段压低的程度进行观察。结果表明,冠心病与对照组心率在6～12时相最快,2～6时相最慢。冠心病组ST段压低的检出率在6～12时相最高。自身对比,昼夜间的差异有显著性(P<0.05)。38例ST段压低中有6例无痛性的。冠心病组室性和房性心律失常检出率高于对照组(P<0.05)。心律失常恶性度及ST段压低在心率减慢时减轻,提示6～12时相对冠心病,心律失常预测的重要性。更多还原

【Abstract】 46 patients with coronary heart disease (CHD) were holter monitored for 24 hours on heart rate rhythm and depression of ST segment in ECG. comparied with normal subjects and anaylized. The results revealed that the heart rates of CHD patients and normal group were the highest in the period of 6:00～12:00 am and the lowest in the period of 2:00～6:00 am. In CHD patients the detactable rate of depression of ST segment was the highest between 6:00～12:00 am. The variation between day and night in same patient was evident (P<0.05). Six of the thirty-eight patients with depression of ST segment were painless. Detactable rate of ventricular and artrial arrhythmia in CHD group were higher than that in the control (P<0.05). The malignaney of arrhythmias and the degree of depression of ST segment were decreased in the period of heart rate decreased. It was suggested, that the dectation in the period of 6:00～12:00 am is very inportant for the patients of CHD and arrhythmias.更多还原
