When to Use Cardiac Magnetic Resonance Imaging for Patients with Premature Ventricular Complexes Referred by Cardiologists

What this Trial Is About

Premature ventricular complexes PVC are common, affecting about 20% of people. They may appear unexpectedly on an electrocardiogram ECG or cause symptoms like palpitations, chest pain, or fainting. Initial tests such as Holter ECG monitoring, echocardiography, and exercise stress tests help exclude structural heart disease, but sometimes subtle heart abnormalities may be missed. Cardiac magnetic resonance CMR imaging is the best way to assess heart function and detect issues like swelling, fatty replacement, or scarring in the heart muscle, but its exact role in patients with PVC is still unclear. This observational study aims to find out when CMR should be used to provide additional diagnosis or prognostic information beyond initial tests for patients referred for PVC by their cardiologists. The study will observe patients who have already had ECG, Holter ECG, and CMR scans, focusing on identifying myocardial abnormalities using CMR. Participants will be adults with PVC who have undergone these heart assessments. Researchers will review CMR results to count detected heart abnormalities and analyze factors that predict these findings. The main measurement is the number of myocardial abnormalities identified by CMR on the first day. This study will help clarify the value of CMR in evaluating PVC and guide future heart care for these patients.
