Figure 3 Normal Post-Ectopic Blood Pressure and R-R Interval Changes
Averaged profiles (mean ± 95% confidence interval) of R-R intervals, systolic arterial blood pressure (SBP), stroke volume (SV), and peripheral vascular resistance (PVR) after VPCs expressed in relative numbers (with 100% corresponding to pre-VPC value) in patients with normal left ventricular function. R-R intervals numbered –1 and –2 indicate those preceding the VPC; the first 2 post-VPC sinus R-R intervals are numbered 1 and 2. Modified, with permission, from Wichterle et al. (17). Abbreviations as in Figure 1.
