title: Biventricular pacing using two pacemakers and the triggered VVT mode.
abstract: Pacemaker dependent patients exhibit interventricular conduction delay due to right ventricular lead placement. The addition of a transvenous coronary sinus lead for biventricular pacing has been shown to be effective. Venous stenosis and thrombosis postpacemaker implantation can occur in up to 35% of patients. This report describes a patient with a preexisting left-sided dual chamber pacemaker and chronic left subclavian vein occlusion that was upgraded to a biventricular system byplacing a coronary sinus lead and single chamber ventricular triggered pacemaker on the opposite side.
