This advanced module in the ECG Summit series explores the diagnostic significance of abnormal QRS morphologies, including tall, wide, or bizarre complexes. Under the expert guidance of Dr. Aditya Kapoor, and moderated by Dr. S.B. Gupta and Dr. Amit Vora, the session delves into the interpretation of ECG changes associated with ventricular hypertrophy, bundle branch blocks, and fascicular blocks. Attendees will learn to identify key electrocardiographic patterns, differentiate between left and right-sided conduction abnormalities, and understand their clinical implications. This module equips clinicians with essential tools to interpret complex ECG findings accurately and enhances decision-making in cardiac care.
