In patients with the acute stage of myocardial infarction the ratio between the maximum rates in the different and afferent parts of the vectocardiographic ST--T loop decreases sharply and, accordingly, the ratio between the amplitudes of the second phase of the T wave and the first phase on the first ECG diminishes. The time needed for attaining the maximum value of acceleration in the initial phase of rapid repolarization is simultaneously reduced. With the gradual recovery of the patients, these indices tend to return to normal. During the bicycle ergometric test in patients with chronic ischemic disease of the heart the reduction of these indices is revealed more frequently and at lesser loads than the shifts which are characteristic of the ordinary ECG recorded in coronary insufficiency.
在心肌梗死急性期患者中，心电向量图ST - T环不同传入部位的最大速率之比急剧下降，相应地，首次心电图上T波第二相与第一相的振幅之比减小。快速复极初始阶段达到加速度最大值所需的时间同时缩短。随着患者逐渐康复，这些指标趋于恢复正常。在慢性缺血性心脏病患者进行自行车运动试验时，与冠状动脉供血不足时记录的普通心电图特征性变化相比，这些指标的降低更频繁且在较小负荷时即出现。
