本文主要讨论冠心病心电图诊断上,非特异性ST-T变化及假性Q波对诊断的影响。冠状动脉缺血的心电图表现对心电复极波的影响:QRS波是反映心室的毁极波。复极波就是ST段和T波。正常ST段有两个特点:①ST段光滑地融入T波的近侧肢,因此不能明确地指出那里是ST段的终点,那里是T波近侧肢的起点。②ST段不在等电线上停留,时间不超过0.12秒。一般在QRS之后,立即离开等电线,上抬,与T波融合(图1)。冠状动脉(简称冠脉)缺血时:(1)ST-T交界点清晰可辨,ST段不再是光滑地融入T波近
This article discusses the diagnosis of coronary heart disease, non-specific ST-T changes and false Q waves on the diagnosis. Electrocardiographic Coronary Ischemia Performance of Electroacupuncture Complexes: QRS waves reflect ventricular dysfunction waves. Polar wave is the ST segment and T wave. There are two characteristics of normal ST segment: ①ST segment smoothly into the T-wave proximal limb, it can not be clearly pointed out there is the end of the ST segment, where is the starting point of T-wave proximal limbs. ② ST segment is not waiting on the wire, the time does not exceed 0.12 seconds. Normally after the QRS, immediately leave the other wires, lift, and T-wave fusion (Figure 1). Coronary artery (referred to as coronary artery) ischemia: (1) ST-T junction clear, ST segment is no longer smooth into the T wave
