Longer Paced QRS Duration is Associated With Increased Prevalence of Right Ventricular Pacing‐Induced Cardiomyopathy

Abstract

Patients with frequent RV pacing and paced QRS duration ≥150 milliseconds should be screened by echocardiogram to assess for PICM. Patients with paced QRS duration <150 milliseconds likely do not require screening, in the absence of heart failure signs or symptoms.
