心率变异(Heart Rate Variability,HRV)虽然早已被认识,但在心血管临床实践中还是常常被忽视。心脏病学家通过长期的临床观察早已认识到心脏不规则的跳动,例如,心房颤动和室性异位激动等是一种病理表现,提示心脏自身的节律调节机制受到了损害,而这在许多种心脏疾患中是不良的预后指标。近些年来,临床医生惊奇地发现,除了心脏不规则跳动外,心脏窦性心律的绝对规则跳动也揭示心脏的节律调节功能受
Although heart rate variability (HRV) has long been recognized, it is still often overlooked in cardiovascular clinical practice. Long-term clinical observation by cardiologists has long recognized irregular heart beat, for example, atrial fibrillation and ventricular ectopic activation is a pathological manifestation, suggesting that the heart’s own rhythm regulation mechanism has been compromised, which in many species Heart disease is a poor prognostic indicator. In recent years, clinicians have been surprised to find that, in addition to irregular heart beating, the absolute regular beat of the sinus rhythm of the heart reveals the rhythmic regulatory function of the heart
