It is for a 58 yr old male with IHD, S/P CABG, MV Repair in 2016. Severe LV dysfunction, LVEF 20%. Presented with progressive HF symptoms. MPI was done and showed mild ischemia in the mid anterior wall and in the inferior wall. Echo showed severe MR despite excellent initial repair results. They showed me the ECG today and I said the following:
This is a rare form of true trifascicular block. There is RBBB + LAFB + LSFB (QRS duration 156 ms).
Do you agree or have other alternatives?
Thank you in advance for your help.
