Effect of dual chamber atrioventricular sequential pacing on coronary flow velocity in a patient with hypertrophic obstructive cardiomyopathy.
Effects of dual chamber AV sequential pacing on coronary flow velocity, especially systolic reversal flow, were tested in a patient with hypertrophic obstructive cardiomyopathy. AV sequential pacing with shorter AV delays reduced the systolic reversal flow in the coronary artery, and improved the pressure gradient of the left ventricular outflow tract.
