Comparison of ventricular late potentials in patients with cardiomyopathy and healthy controls

ABSTRACT

Background: Ventricular late potentials [VLPs] are low amplitude high frequency signals present in the terminal part of QRS complex detected by signal averaged ECG. They have emerged as robust tools for arrhythmia risk stratification in patients with cardiac diseases. Early detection of ventricular late potentials in patients with cardiomyopathy can help in risk stratification of ventricular arrhythmias leading to sudden cardiac death. The purpose of this study was to compare VLPs in patients with cardiomyopathy and healthy controls
