What is Heart rate turbulence (HRT)?
- Dr.QutubLv 77 years agoFavorite Answer
Heart rate turbulence (HRT) is the return to equilibrium of heart rate after a premature ventricular contraction (PVC). It consists of a brief speed-up in heart rate, followed by a slow decrease back to the baseline rate. An important feature of HRT is that PVCs occur naturally in most adults, so measuring the characteristics of a given person's HRT offers a noninvasive way to evaluate his or her cardiac function without applying artificial external stimuli.
The measured values of HRT parameters have been shown to be a statistically significant predictor of the probability of dying from cardiac disease after a patient suffers a myocardial infarction. HRT can also be used to predict death in patients with congestive heart failure from a lethal arrhythmia.
HRT has nothing to do with turbulence in fluid dynamics.
