Abstract The two most common modes of death among chronic heart failure (CHF) patients are sudden cardiac death (SCD) and pump failure death (PFD). Periodic repolarization dynamics (PRD) quantifies low-frequency oscillations in the T wave vector of the electrocardiogram (ECG) and has been postulated to reflect sympathetic modulation of ventricular repolarization. This study aims to evaluate the prognostic value of PRD to predict SCD and PFD in a population of CHF patients. 20-min high-resolution (1000 Hz) ECG recordings from 569 CHF patients were analyzed. Patients were divided into two groups, $$\hbox {PRD}^+$$ PRD + and $$\hbox {PRD}^-$$ PRD - , corresponding to PRD values above and below the optimum cutoff point of PRD in the study population. Univariate Cox regression analysis showed that SCD risk in the $$\hbox {PRD}^+$$ PRD + group was double the risk in the $$\hbox {PRD}^-$$ PRD - group [hazard ratio (95% CI) 2.001 (1.127–3.554), $$\hbox {p} |
