Abstract

In order to assess the timing relationship between corresponding oscillatory components of systolic (SAP) and diastolic (DAP) arterial pressure, 8 min resting recordings of SAP and DAP were analyzed in 23 post-myocardial infarction (MI) patients, 24 chronic heart failure (CHF) patients showing a periodic breathing pattern (CHF-PB), 15 CHF patients with normal breathing (CHF-NB) and 18 controls. The coherence and phase spectrum between SAP and DAP were estimated and from the latter the time delay at the VLF, LF and HF components derived. A consistent delay between DAP and SAP in the VLF band was found in all four groups considered. The delay was higher in CHF patients, with mean value ≈3.5 s, and lower in MI patients (1.7 s, p
