Abstract:
The idiopathic mitral valve prolapse(IMVP) syndrome presents with nonspecific cardiovascular symptoms which need to evaluate those clinical meaning. These symptoms should not necessarily be interpreted as suggesting arrhythmias, conduction abnormalities or myocardial ischemia unless the symptoms and the the electrocardiographic changes documented to occur simultaneously. And it will be that ambulatory electrocardiographic monitoring is a a very sensitive method to detect the transient arrhythmias, conduction abnormalities of ischemic changes in patients with IMVP. Author undertook a study to systemically evaluate the electrocardiographic findings in symptomatic patients with IMVP by means of 24 hour ambulatory Holter electrocardiographic monitoring for the evaluation of the clincal meaning of those symptoms. The following results were obtained; 1) Twenty five subjects, 15 male and 10 female, with IMVP were studied. The subjects ranged in age from 10 to 50 decades. 2) The presenting complaints were palpitation in 20, atypical chest pain in 17, dizziness and syncope in 9, and lyspnea and fatigue in 7 of 25 studied subjects. 3) There were no correlations the presence of complaints with the routine 12 lead electrocardiographic findings, echocardiographic findings, and phonocardiographic findings. 4) The relationship of symptoms recorded in patient diary to Holter monioring electrocardiographic findings is summarized. (1) 20 patients recorded episodes of palpitation. Seven of these patients was associated with sinus tachycardia, 2 with paroxysmal atrial tachycardia, 3 with atrial fibrillation, 2 with atrial premature contractions, 5 with ventricular premature contractions, and 1 with no changes, (2) 17 patients recorded episodes of atypical chest pain. Three of these patients was associated with sinus bradycardia, 2 with sinus tachycardia, 1 with paroxysmal atrial tachycardia, 2 with atrial finbrillation, 2 with ventricular premature contractions, 3 with nonspecific ST segment change, 1 with first degree AV block, and 3 with no changes. (3) 8 patients recorded episodes of dizziness. Three of these patients was associated sinus bradycardia, 2 with paroxysmal atrial tachycardia, 1 with paroxysmal ventricular tachycardia, 1 with ventricular premature contractions, and 1 with no changes. (4) 1 patient recorded episodes of syncope associated with second degree AV block and sinus bradycardia. (5) 3 Patients recorded episodes of dyspnea. One of these patients was associated with sinus bradycardia, 1 with ventricular premature contractions and one with no changes. 5) The prolonged QTc interval revealed in 7 of 25 studied subjects. One of these had frequent ventricular contractions followed by paroxysmal ventricular tachycardia. 6) Ectopic beats associated with bradyarrhythmias tend to decrease in frequency and associated with tachyarrhythmias to increase in frequency in patients with atrial premature contractions during exercise, and with ventricular premature contractions during sleeping, respectively. 7) Bradyarrhythmia accounted for the majority of arrhythmias recorded in 15 of 25 symptomatic IMVP patients. It is concluded that Holter monitoring is of considerable value in assessing the clinical meaning of the nonspecific complaints in patinets with IMVP.
