Progressive Paced QRS Widening: An Electrocardiographic Marker for Predicting Cardiac Resynchronization Therapy Upgrade

Progressive widening of pQRSd represents a novel, clinically accessible marker for identifying patients at high risk for CRT upgrade. Monitoring pQRSd trends through routine electrocardiogram (ECG) provides an effective strategy for early identification of patients who might benefit from CRT before developing advanced heart failure.

Abstract

Progressive widening of pQRSd represents a novel, clinically accessible marker for identifying patients at high risk for CRT upgrade. Monitoring pQRSd trends through routine electrocardiogram (ECG) provides an effective strategy for early identification of patients who might benefit from CRT before developing advanced heart failure.
