Abstract

Cardiovascular oscillations following spontaneous ventricular premature complexes (VPC) are described by the so-called heart rate turbulence (HRT) onset (TO) and slope (TS). Since HRT is a marker of baroreflex sensitivity, it can be hypothesized to be affected by the preceding VPC sympatovagal balance (pHF). The aim of this study is to investigate the relationship between HRT parameters and pHF in heart failure (HF) patients. We studied 75 24h ECG Holter recording of HF patients (62±9 years) performing a Spearman correlation analysis between TO, TS and pHF values. According to risk stratification standards, each post-VPC response was classified in 0-normal type or 1-abnormal category. Results showed a 53%, 27%,5%,6% of post-VPC respectively 0, 1a, 1b, 2-category, and a remaining 9% unclassified T0=0 values. pHF showed a moderate to good significant (p
