Key result
Alcohol septal ablation for HOCM induced significant resting ECG changes, including immediate right bundle branch block in all 9 patients and new Q waves in 4 patients.

Expected post-ablation ECG changes require careful interpretation in HOCM; extends procedural characterization but leaves prognostic value open.

Does alcohol septal ablation induce significant electrocardiographic changes in patients with hypertrophic obstructive cardiomyopathy?
Alcohol septal ablation for HOCM induces significant resting ECG changes, including bundle branch blocks and transient QT prolongation, despite occluding a relatively small artery.
Kaźmierczak et al. (1998) conducted an observational in Hypertrophic obstructive cardiomyopathy (HOCM) (n=9). Alcohol septal ablation was evaluated on Acute and mid-term electrocardiographic changes and their relation to left ventricular outflow tract pressure gradients. Alcohol septal ablation for HOCM induced significant resting ECG changes, including immediate right bundle branch block in all 9 patients and new Q waves in 4 patients.
