title: The effect of bundle branch block on heart function and cardiac output in premature infant.
abstract: It is well known that hyperkalemia may cause arrhythmia, right bundle branch block, and cardiac conduction block. These dysrhythmias have the potential to affect cardiac function. We present a premature newborn with hyperkalemia and right bundle branch block causing left ventricular dyssynchrony with mitral regurgitation, which led to decreased pump function.
