摘要
对72例疑为冠心病患者进行运动心电图负荷试验,观察P波时间及振幅的动态变化。结果:72例受试者S─T段呈缺血性改变者35例,P波振幅增高在1.0~1.8mm者8例(11.1%),T、P等高并部分融合7例(9.72%);P≥R,7例(9.72%)。P波出现切迹、双峰间距>0.04s4例。主要表现在Ⅱ、Ⅲ、avF导联。在35例运动负荷试验阳性中,P波动态变化者7例,占20%。结论:运动负荷试验后出现P波时间及振幅的变化,是反映心房异常的一项敏感指标,可有助于冠心病及高血压性心脏病的诊断。
caeses suspected coronary heart disease were conducted an electrocardiogram test of exercise load and observed for the dynamic change of P wave and amplitude. The results show as follow: among 72 cases, there are 35 cases S-T parts show ischemic change; 8(11.1%)cases-P wave amplitude increasing is tetween 1.0~1.8mm; 7(9. 72%)whose T and P equal in height and mix to come extent7 (9. 72%);P≥R. 4 whose P wave reveals mitral valve type P wave and the distance btween two peaks greater than 0.04S. The main manifestation is the connection of Ⅱ, Ⅲ and avF. Among 35 cases with positive reaction in the exercise load test, there are 7 who undergo the dynamic change of P wave, amount to 20%.It is my view that the dynamic change of P wave time and amplitude serves as a sensitve indicat or to the diagnosis of coronary heart disease and hypertensive heart disease.
