Evaluating patients with ventricular arrhythmia. Role of the signal-averaged electrocardiogram, exercise test, ambulatory electrocardiogram, and electrophysiologic studies.

There are several methods available for the evaluation of patients with ventricular arrhythmia. The most effective approaches, however, involve the use of techniques that provide objective data. These include ambulatory monitoring and exercise testing (a noninvasive approach), and electrophysiologic testing (invasive). The information derived from these two approaches is complementary, and both are important for patient evaluation and management. These methods are useful for establishing the risk of arrhythmia occurrence in certain patient groups and for establishing the effect of antiarrhythmic agents. The signal-averaged ECG is of help in establishing risk in some patient groups, but it has no role for evaluating drug therapy.
