Endocardial electrical stimulation is a diagnostic technique for evaluating sinus node function, the atrioventricular conduction system, and tachyarrhythmias. Electrode catheters inserted into the heart detect and stimulate cardiac electrical activity to provide information about the heart's electrical conduction system. Because activity is measured in several sites, several catheters must be placed in the right heart ventricle and, at times, in the left heart ventricle (1, 2). When severe or life-threatening arrhythmias are induced during stimulation, the efficacy of pharmacologic agents in preventing or suppressing the initiation of these arrhythmias may be evaluated.
Although pacing protocols differ among centers (3, 4),
