dc.description.abstract | This study determines the results of programmed stimulation in patients with syncope or near-syncope presumed to have the carotid sinus syndrome based on the finding of carotid sinus hypersensitivity and the absence of any other apparent cause for syncope or near-syncope after clinical evaluation. Fourteen patients had coronary artery disease, 1 had dilated cardiomyopathy and 18 patients did not have structural heart disease. Programmed simulation was performed at 2 basic drive cycle lengths and 2 right ventricular sites with 1 to 3 extrastimuli. Sustained unimorphic ventricular tachycardia (VT) was induced in 5 of 15 patients who had structural heart disease, and in none of the 18 patients who did not (p 0.05). Patients who had inducible unimorphic VT were treated with antiarrhythmic drugs that suppressed the induction of VT, and 4 of 5 patients also received a pacemaker; no patient had a recurrence of syncope during followup. Patients who had inducible polymorphic VT and VF (n = 10) or no inducible VT (n = 18) received treatment directed at only carotid sinus syndrome. Two patients with inducible VT or VF and 1 patient without inducible VT had recurrent syncope during follow-up, but none had cardiac arrest or died suddenly. It is concluded that programmed stimulation should be performed in patients presumed to have carotid sinus syndrome who have structural heart disease; unimorphic VT may be induced in one-third of these patients, raising the possibility that VT is the cause of syncope. Antiarrhythmic drug therapy may be unnecessary if polymorphic VT or VF is induced. In patients without heart disease, programmed stimulation is highly unlikely to yield a clinically significant arrhythmia. | en_US |
