Abstract

Head-up tilt test (HUT) is frequently used for diagnosis of neurocardiogenic syncope. It mimics orthostatic stress resulting in venous pooling, central hypovolemia with compensated left ventricular hypercontraction, and sympathetic stimulation. Although generally considered to be a safe procedure, we hereby present a rare complication of HUT in a 50-year-old woman with isoproterenol infusion inducing coronary spasm that resulted in ventricular tachycardia.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
