Hey, there. Recently did an ECG+echo at my cardiologist, he said everything is fine except the slowed heart rate (I was taking beta blockers for high BP, so he recommended stopping taking them).
Didn't pay much attention to the ECG itself until i saw it all seems jagged, compared to the "normal" ones everywhere on google which are a lot smoother especially in the V1-V6 sections. Can anyone interpret what the cause might be? is that normal?
TLDR: Is the provided ECG normal (it is according to my doc except for slow heart rate), why are curves in V1-V6 so jagged?
It's fine.
Essentially Beta Blockers are used to reduce hypertension in the heart/blood vessels.
It's Jagged and slightly drawn out because they reduce the effect of the electrical stimulation in the heart. That's fine because otherwise the pressure would be too much and might damage the vessels.
