Question:
Will LBBB progress to complete heart block?
April 2011 routine physical ECG was normal. April 2012 routine physical ECG showed PRWP and inverted T waves - Transesophageal echocardiogram done all OK. July 2012 checked ECG again, now LBBB - another echo (all OK) and Nuclear stress test perfusion, etc., all OK. No symptoms, 41 year old woman. PMH: IBS brother died of heart attack aged 36. Will LBBB progress and get worse? Develop total block? Do I need a pacemaker?

LBBB [left bundle branch block] does not necessarily progress to complete heart block. Everything else being normal, you should lead a normal lifestyle, and continue medical follow and coronary risk control.
