Insights
Mitral valve prolapse patients frequently experience ventricular extrasystolic contractions. Precise arrhythmia evaluation requires carefully selected patient groups for accurate mitral valve prolapse research.
Area of Science:
- Cardiology
- Cardiac Electrophysiology
Context:
- Mitral valve prolapse (MVP) is a common cardiac condition.
- Cardiac arrhythmias can occur in patients with MVP.
- Understanding the incidence of arrhythmias in MVP is crucial for patient management.
Purpose:
- To evaluate the incidence of cardiac arrhythmias in patients diagnosed with mitral valve prolapse (MVP).
- To identify the most common types of arrhythmias associated with MVP.
Summary:
- This study assessed 119 patients with mitral valve prolapse (MVP) using clinical symptoms, echocardiography, and 24-hour Holter monitoring.
- Ventricular extrasystolic contractions, specifically Lown's class 1a and 1b, were found to be the most frequent arrhythmias in MVP patients.
- The study highlights the need for strictly selected patient cohorts to accurately determine arrhythmia incidence in MVP.
Impact:
- Provides insights into the electrophysiological complications of mitral valve prolapse (MVP).
- Informs clinical practice regarding arrhythmia monitoring in MVP patients.
- Guides future research by emphasizing the importance of patient stratification for accurate data collection.
Abstract:
An incidence of cardiac arrhythmias was evaluated in 119 patients with mitral valve prolapse. The disease was made basing on the results of clinical symptoms, echo-, angio- and phonocardiography. Electrocardiograms were recorded from the standard 12 lead and Holter technique for 24 hours in each patient to assess present arrhythmias. It was found that the most frequent cardiac arrhythmias accompanying mitral valve prolapse are ventricular extrasystolic contractions of Lown's class 1a and 1b. Only examination of strictly selected groups of patients (age groups with or without co-existing mitral valve insufficiency for adequate period of time) will facilitate precise evaluation of an incidence of different cardiac arrhythmias accompanying the underlying disease.
