Combined Use of Labetalol and Nifedipine in Controlling the Cardiovascular Response From ECT

Serious cardiac complications have been reported to occur in elderly depressed patients during a course of electroconvulsive therapy (ECT). As a result, cardiac medications are being used more often to dampen the cardiovascular response that occurs during an ECT treatment. Specifically, labetalol (a mixed alpha- and beta-blocker) has been shown to effectively control the heart rate during ECT. However, on occasion, patients may still exhibit sustained elevations of blood pressure during ECT when receiving labetalol. The optimum clinical management of these patients is unclear. The authors report on the safety and efficacy of combining nifedipine with labetalol to control blood pressure during ECT in ten elderly patients whose blood pressures were not adequately controlled by labetalol alone. No adverse effects were noted, nor did nifedipine appear to shorten seizure duration.
