“…-6 Previous studies have focused on the characteristics of premature ventricular beats initiating ventricular tachycardias (VT) and changes in basic heart rate preceding the spontaneous episodes of VT. [1][2][3][4][5][6] By analyzing the power spectral components of the heart rate variability (HRV), however, it is possible to estimate neural, hormonal, and other influences on the heart,7-9 reflecting modulation of the electrophysiological substrate by functional influences. '0 Recent studies have revealed that low total HRV and low measures of various frequency domain components of HRV can identify patients who are at increased risk of arrhythmic events after myocardial infarction.…”
