Thanks Yousef  Questions/comments:

1.Although His pacing makes physiological sense, however, it is cumbersome and can be tedious. Do we have data to support superiority over RV pacing for this patient with preserved EF?

2.The pacing EKG does not look "pure"  HBP. The QRS is wider than baseline EKG and there is a significant axis shirt (from right at baseline to extreme left on paced EKG), how to explain that? do you think it is capturing some other fascicular elements instead, with or without some RV? a post implant CXR will be very helpful if you have it.

3.What is HBP threshold?

Great case!
