Long-term ventricular pacing in treatment of sinoatrial block.
Six patients with symptoms due to sinoatrial block are described in whom no relief or improvement in block occurred when they were treated with isoprenaline or ephedrine. All six patients were treated by ventricular cardiac pacing with complete relief of symptoms. Despite the theoretical disadvantages of parasystole and loss of accrochage in treating these patients by ventricular pacing they have survived for periods of 18 months to over five years.
