Time-Frequency Analysis of the RT and RR Variability to Stratify Hypertrophic Cardiomyopathy Patients


The RT interval is a measure of the ventricular repolarization and is partially influenced by the sympathovagal balance. The analysis of the variation of the duration of the RT and RR intervals might bring new information about the arrhythmogenic vulnerability and autonomic imbalance. The RR signal and its spectral density (SD) are characterized by two… (More)
