Mobitz I and Mobitz II
I understand the descriptions for Mobitz I and Mobitz II grade 2 type heart blocks.
What I am struggling with is what would the explanation be for having both in the same person.
I know I have a long PR interval and I know the EP said that sometimes my heart would drop a beat after increasingly lengthening PR intervals. That makes sense and would come under Mobitz I and suggest I have a problem with the AV node.
However I also at one point was in a 2:1 block. So this suggests a Mobitz II.
The literature suggests Mobitz I very rarely progresses to full heart block.
Mobitz II can progress to full heart block as they have problems with the bundle of His.
My question is, what is the explanation for me having both Mobitz I and II during those few days I was on ECG?
Does it suggest I have problems in both by AV node and bundle of His?
