本文对心功能Ⅰ—Ⅱ级、心功能Ⅲ—Ⅳ级患者和健康人心舒间期与心率相关分析。结果表明患者和健康人心率与心舒间期百分比PDT均呈指数关系。当心率100次/min,心功能Ⅰ—Ⅱ级患者PDT比健康人减少4％,心功能Ⅲ—Ⅳ级患者PDT比健康人减少7％。心功能Ⅰ—Ⅱ级,心功能Ⅲ—Ⅳ级患者心率与PDT回归曲线与健康人心率与PDT回归曲线分别相交在心率91次/min和心率84次/min。心功能Ⅲ—Ⅳ级患者PDT与PEP/LVET呈负相关。提示慢性充血性心力衰竭患者心率加快时,加剧心内膜下心肌缺血和心功能恶化。
In this paper, cardiac function Ⅰ-Ⅱ level, heart function Ⅲ-Ⅳ grade patients and healthy people and the inter-patient relationship between heart rate and heart rate. The results showed that the heart rate of patients and healthy persons and the percentage of inter-ventricular interphase PDT are exponential. When heart rate was 100 beats / min, PDT in patients with grade I-II cardiac function decreased by 4% and PDT in patients with grade III-IV cardiac function decreased by 7% compared with healthy people. Heart rate and PDT regression curves in patients with grade I-II cardiac function and grade III-IV cardiac function were compared with PDT regression curves at heart rate 91 beats / min and heart rate 84 beats / min. PDT was negatively correlated with PEP / LVET in patients with grade Ⅲ-Ⅳ cardiac function. Prompt heart rate in patients with chronic congestive heart failure, exacerbation of subendocardial myocardial ischemia and cardiac dysfunction.
