Mitral valve prolapse: a review of associated arrhythmias.

The syndrome of mitral valve prolapse with associated auscultatory-electrocardiographic findings is now well documented. Two representative cases of repetitive tachyarrhythmias in patients with mitral valve prolapse are discussed as well as an analysis of the 589 cases in the English literature of arrhythmias in patients with mitral valve prolapse. The average age of the patients was 38 years; 70 per cent of them were women. Symptoms were variable, but palpitations occurred in 44 per cent, lightheadedness in 12 per cent and syncope in 4 per cent. Premature atrial and/or ventricular contractions were found in 55 per cent, premature ventricular contractions in 45 per cent, supraventricular tachycardia in 6.1 per cent and ventricular tachycardia in 6.3 per cent. Sudden death was noted in 1.4 per cent. A discussion of the pathogenesis of arrhythmias and therapy concludes this review.

The normal electrocardiogram as a predictor of left ventricular function in patients with coronary artery disease.

Fifty-five consecutive patients with a normal resting electrocardiogram and coronary artery disease were examined to determine left ventricular function. Fifty-two (95%) had no evidence of left ventricular asynergy; 3 patients had only mild hypokinesis. Of this group of patients, 25 (47%) had one vessel disease, 17 (30%) had two vessel disease, and 13 (23%) had three vessel disease. Significant left ventricular asynergy was not found in patients with coronary artery disease and normal electrocardiograms. In addition, a normal electrocardiogram was not related to the number of coronary arteries involved.

Dermatoglyphic patterns in patients with mitral valve prolapse: a clue to pathogenesis.

Fingerprints were obtained from 100 patients with mitral valve prolapse and compared with those of 100 control subjects matched for sex and race. Arches were found in 16.8 percent of all digital patterns in patients with mitral valve prolapse but in only 2.5 percent of all digits in the control group. Whereas no patient in the control group had four or more arches, 19 percent of patients with mitral valve prolapse had this finding. In addition, arches were found on 16 and 9 percent, respectively, of digits IV and V in patients with mitral valve prolapse but were not found on these digits in the control group. The finding of four or more arches or arches on digits IV or V may be important supportive evidence of mitral valve prolapse when evaluating patients with atypical chest pain and palpitations. Antenatal factors may be involved in the pathogenesis of mitral valve prolapse since it is possible that a genetic or environmental factor that interferes with the development of the mitral valve may also influence epidermal ridge patterns.
