Significance of my Holter monitor

I cannot comment on the atenolol as I have no history of it...sorry. It is a form of beta blocker/rate control which is given to patients who are: experiencing tachyarrhythmia and b: symptomatic. If you don't feel well, have some anxiety, sense both the onset/precursor sensations to an episode and then the palpitations themselves, and they are intrusive to the point where you almost have to stop doing anything else, then the beta blockers can help. But each patient must be their own trial/experiment to see if they can tolerate the drug and if it actually works. This means also being your own strong advocate for what is working or what you cannot use efficiently or comfortably (it brings on symptoms that might actually be worse than the arrhythmia's sensations).

If we can assume that the results of the Holter are veridical (verifiably accurate), then your 'apparent' burden is low. It isn't until your burden rises to 3% that it is deemed in most medical circles that you're a candidate for an intervention beyond medications. At that point you should be seeing a heart specialist known as an 'electrophysiologist', or EP for short. I have had two ablations to stop atrial fibrillation, each time performed by an EP. Second one worked and I have been free of that troubling arrhythmia for just a few days over three full years. So, a top tier EP, with a solid reputation, will probably be able to help you...in time.

If your heart's inner works, its substrate, the four valves, and the arteries feeding the myocardium, are all in good order, then this might just be a genetic thing happening or 'normal' aging....for you. I assume your mitral valve is in good shape, no stenosis or prolapse? There is no detectable ischemia? (usually a treadmill stress test with contrast dye and a CT scan tell the story, but so can a CT angiogram).

Sometimes comorbidities or lifestyle 'problems' can be the cause. Too much adiposity, especially viscerally deposited too closely and in too much mass around the organs. A bit of hypertension, or a lot of it, for too long. Diabetes or metabolic syndrome. COPD....the list goes on and they all put a strain on your vasculature and on the heart itself. I make no assumptions about you since we haven't met, but perhaps one or more of these needs...................work.

Hi Cesar,
I am 82 years old and female, but all my tests -- heart, lungs, etc. -- have come back normal. Yet I also had unusual heart measurements and was put on Metoprolol which is also a beta blocker. It did lower my heart rate. However I am still experiencing symptoms of light headedness and tiredness. These are the reasons I originally sought medical attention. I am now off Metoprolol because it added to my fatigue

You didn't mention symptoms. Other than the readings on the Holter were you experiencing symptoms?

I have now asked for an appointment with an electrophysiologist as suggested by "gloaming". I am always impressed with his input as he is very into the research and I always learn something new when reading his responses.

Good luck on your journey.

Dana
