Relationship between pulse transit time and blood pressure is impaired in patients with chronic heart failure

Aims Pulse transit time (PTT), the interval between ventricular electrical activity and arrival of the peripheral pulse wave, has been used to detect changes in autonomic tone during sleep and anesthesia. The purpose of this study was to evaluate PTT in patients with chronic heart failure (HF). Meth...

Zusammenfassung:	Aims Pulse transit time (PTT), the interval between ventricular electrical activity and arrival of the peripheral pulse wave, has been used to detect changes in autonomic tone during sleep and anesthesia. The purpose of this study was to evaluate PTT in patients with chronic heart failure (HF). Methods and results Pulse transit time was measured with R-wave gated photoplethysmography in 24 healthy volunteers and in 112 patients with chronic HF and ejection fraction (EF)
