Abstract

Arrhythmias have been reported to occur frequently in symptomatic patients with mitral valve prolapse (MVP). The mechanisms causing atrial arrhythmias in patients with MVP have not been fully investigated. The purpose of this study was to determine the clinical, echocardiographic and heart rate variability parameters, and plasma concentrations of electrolytes and inflammatory markers in predicting atrial arrhythmias in patients with MVP. A total of 58 consecutive patients with MVP were included in this study. We performed electrocardiography, echocardiography, Holter analysis, routine biochemical tests including plasma concentrations of electrolytes and inflammatory markers, and evaluated the clinical characteristics. Atrial arrhythmia was defined as occurrence of any of the following: atrial premature contractions, atrial couplets, supraventricular tachycardia, atrial flutter or fibrillation documented by Holter analysis, continuous monitoring or by electrocardiography. Twenty-eight patients (48%) had atrial arrhythmias, and 30 (52%) patients had no atrial arrhythmias. Univariable predictors of atrial arrhythmias included isovolumetric relaxation time, lateral systolic (S'), lateral late diastolic (A'), septal A' Doppler veloc...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
