[Programmed atrial and ventricular stimulation in patients with mitral valve prolapse--a personal experience].
Electrophysiological tests were performed in 60 patients aged between 18 and 63 years (mean age 38 years), and divided into two groups: with mitral valve leaves prolapse syndrome, and without this abnormality, in whom no other heart disease was diagnosed. Refraction of the right atrium, atrio-ventricular node, and right ventricle was evaluated together with cardiac response to different types of electrostimulation. A supraventricular dysrhythmia (most frequently atrial fibrillation) has been produced in 17 patients (42.5%) with mitral valve leaves prolapse syndrome whereas in the control group the same was produced in 2 patients (10%). Programmed stimulation of the ventricles did not produce ventricular tachycardia in none patient of both groups. Multiple ventricular beats have been produced in 3 patients with mitral valve prolapse syndrome and pairs of ventricular beats in other 3 patients of this group. Results suggest that "arrhythmogenic tendency", especially supraventricular dysrhythmia is more frequent in patients with mitral valve prolapse syndrome than in the general population.
