Heart zones - Heart Zones is a fitness, health, and sports performance training methodology developed by professional triathlete Sally Edwards in 1992 with the publishing of her book The Heart Rate Monitor Book. The training system uses the heart as the core for the training program, zones as the range of training intensity, and training as a method of attaining goals through fitness effort.
Heart rate variability - Heart rate variability (HRV) is a measure of variations in the heart rate. It is usually calculated by analysing the time series of beat-to-beat intervals from ECG or arterial pressure tracings.
Heart rate turbulence - Heart Rate Turbulence (HRT) is the return to equilibrium of heart rate after a premature ventricular contraction (PVC).
