运动高峰时的心率与收缩压乘积,又称两项乘积或张力-时间指数,是左室作功和心肌氧耗量的一个简单易测、相关良好的指标,在冠状动脉病变引起心肌血供不足及左室功能障碍时,该值明显降低。本文对70例极量心电图运动试验两项乘积的临床意义进行分析,现将结果报告如下。 Heart rate and systolic blood pressure multiplication at peak exercise, also known as the two product or tension - time index, is a simple, easily measurable, well-correlated measure of left ventricular work and myocardial oxygen consumption that causes cardiac blood supply in coronary artery disease Insufficient and left ventricular dysfunction, the value was significantly reduced. In this paper, 70 cases of extreme ECG test two products of clinical significance analysis, the results are reported as follows.
