Mechanical adaptation of heart rate change for coronary circulation in patients with and without ventricular hypertrophy

To clarify the mechanical adaptation and interference of coronary vessels, we studied hemodynamics of coronary circulation in control and 4 different pacing rates (80, 100, 120, 150/min) in 5 patients with angina pectoris (AP) and in 5 patients with hypertrophic cardiomyopathy (HCM). Coronary sinus...
