That is a relief for you.

But I don't understand why fish oil is not being recommended?
Did he say? There are many studies showing improvements in
heart arrhythmias with fish oil. I thought most cardiologists are coming around now to the benefits of fish oil.

Fish oils raise HDLs but do not affect LDLs much.

Also beta blockers can affect lipids. They vary from each other in this regard. (may raise LDL and lower HDL) If you search PubMed you will see.

Beta Blockers are also tough for diabetics.

So you will have to be very vigilant for this consquence.
In your case choosing a more benign beta blocker (I don't recall which you have)...may help.
But benefit vs risk...for heart issues, you may have to live with the potential for diabetes in the future.
Some people do very well on the Zone Diet to control metabolic syndrome and type II.

And I am still not clear on the QT issues. If you do have this, then you will have to check the drug lists I've posted on Chronic Pain (the sticky there) to see if there are any additive things with your other drugs. Also do not get dehydrated, or low in potassium or magnesium. Low values of these two minerals can set off a QT event.

But it is good you show no occlusions at this time.
