TCT-686 There’s More to the ECG: Predictors of Complete Heart Block after Alcohol Septal Ablation for Hypertrophic Obstructive Cardiomyopathy

Predictors of late CHB included prior LVH, new LAD, PR lengthening >40 ms, and QRS duration >140 ms. Conclusion ECGs before and after ASA are helpful in determining who will require PPM or develop late heart block. Alcohol Septal Ablation/HOCM Predictor Odds Ratio (OR) 95% Confidence Interval...
