Preventing Sudden Death: New Sodium Channel Raises Hope For Control Of Cardiac Arrhythmias

Date:
December 3, 1997

University of Maryland, Baltimore
Summary:
Researchers at the University of Maryland School of Medicine have discovered a new type of sodium channel that controls a vital step in the complex electrical process that regulates heartbeat. The discovery could pave the way for the first effective drug therapy to control cardiac arrhythmias.

Like a car, the heart depends on a complex and tightly timed series of electrical and mechanical events to do its job. If its precisely synchronized system malfunctions, the car may stall–and the heart may suffer cardiac arrhythmias, life-threatening disruptions in the coordination of contractions in different regions of the heart muscle needed to keep blood pumping through the body. Arrhythmias kill nearly half a million Americans a year, and there is no effective drug therapy.
