Figure 1 Effects of intravenous verapamil versus 0.5N NaCl on resting cardiovascular hemodynamics. A. Example showing reduction of carotid pulse augmentation index (left panel), increases in left ventricular (LV) volumes (middle) and decline in peak ventricular power (right). Dotted curves are control and solid curves are post verapamil. B. Group data showing effects of verapamil on supine hemodynamics at rest. Open bars show saline data and solid bars verapamil. * = p < 0.05; ** = p < 0.01 between studies. Error bars are SEM.
