THE POTENTIAL ROLE OF DUAL-CHAMBER PACING IN THE MANAGEMENT OF ELDERLY PATIENTS WITH HYPERTROPHIC CARDIOMYOPATHY

It has been suggested that dual-chamber pacing can improve patients wi th drug-refractory obstructive hypertrophic cardiomyopathy. Non-random ized studies have demonstrated functional benefit associated with a la rge decrease in the left ventricular outflow tract (LVOT) gradient dur ing dual-chamber pacing. In elderly patients with drug-refractory obst ructive hypertrophic cardiomyopathy, dual-chamber pacing may significa ntly and durably improve haemodynamic acid functional status, provided that complete ventricular capture is achieved and physiological atrio ventricular synchrony is preserved.
