Is 14% pac burden worth medicating?

I did a 2 week halter monitor, stress test and echo and everything said structure and everything was fine but I have a 14% pack burden and 1% pvc burden. The only other thing noted during the stress test is my heart rate increased more than normal when standing up from a lying down position.

It’s affected my quality of life and was triggering terrible panic attacks. I’ve gotten it mostly under control but I feel kinda fatigued and stressed because I can feel them all day.

I’m working on treating my sleep apnea which the doc says could be the cause because I gave up any and all stimulants and nicotine and no change.

Is it worth it to try medication I was prescribed metoprolol, I’ve read it can have some pretty bad side effects including depression.

Has anyone seen improvements without side effects?
