In patients with chronic coronary artery disease, post-extrasystolic potentiation (PESP) slightly worsens relaxation, increasing the constant tau of ventricular pressure decay. However, it does not negatively influence left ventricular (LV) diastolic filling. To our knowledge, no data are available on the effects of PESP on segmental relaxation in chronic coronary artery disease. The effects of PESP on the LV pressure-volume (P/V) relationship and on segmental pressure-length loops (P/L) were… CONTINUE READING
