  • Title: [Mitral valve prolapse syndrome and arrhythmias].
    Author: Baedeker W.
    Journal: Herz; 1988 Oct; 13(5):318-25. PubMed ID: 3053384.
    Abstract:
    In patients with mitral valve prolapse syndrome various disturbances of cardiac rhythm can be observed such as atrial arrhythmias, ventricular tachycardias and conduction disturbances. Of timely interest are the questions of which etiology is at the basis of the arrhythmias, what is their relevance with respect to sudden cardiac death, what are the indications for treatment and which therapeutic results can be anticipated. Cardiac arrhythmias represent the most frequent complication of mitral valve prolapse. Holter ECG monitoring has assumed the central role in detection of all types of arrhythmias. As compared with normal persons, in patients with mitral valve prolapse, both ventricular and supraventricular arrhythmias can be found more frequently. Atrial arrhythmias: Supraventricular arrhythmias can be found less frequently than ventricular arrhythmias (Table 1). Premature atrial contractions can be observed in 35% of those with mitral valve prolapse but also in a similar number of normal individuals such that their presence is not of clinical relevance. There is only a tendency to more frequently incurred supraventricular couplets in mitral valve prolapse. Supraventricular tachycardias can be observed in 10.5 to 32% of which sinus tachycardia (heart rate greater than 120 beats per minute), paroxysmal atrial tachycardia and intermittent atrial fibrillation at about 5 to 6% each are not more common than in control subjects. Atrial fibrillation was seen more frequently in mitral valve prolapse with mitral regurgitation or, conversely, in mitral regurgitation due to mitral valve prolapse more frequently than in mitral regurgitation due to other causes.(ABSTRACT TRUNCATED AT 250 WORDS)
