Atrial tachycardia
I am 72 and just started with atrial tachycardia episodes. I wore the holter monitor for two weeks which showed it. My EKG was normal and so was the stress test. I am scheduled for an electrocardiogram next month. I also I a follow up with the cardiologist beginning of October.
I have not drank or smoked for 34 years. I only drink 2 cups of coffee each morning.
I am wondering if stevia root can cause heart palpitations? I also was eating protein bars and high protein yogurt. It stopped after I stopped the protein bars but now I had an episode yesterday after not having one for 3 weeks. The lemonade I drink also has stevia in it and so does the yogurt? I am trying to find out why is all? Any help is appreciated.

I am in my 70's as well and have had infrequent tach episodes for over 20 years. Just had another echo and will see the cardio doc next week and will ask about diet causes. No one seems too excited about it. I did a literature search for "stevia root and heart issues" and it returned "no results." One citation: "This patient had no major risk factors for SVT development other than starting an intense weight-loss regime with a ketone-based weight-loss product a few days before the development of the tachyarrhythmia." The authors stated that there is nothing in the literature on this and they will continue to investigate. A broader search with "tachycardia and diet" returned nothing of interest either. Has your medical team mentioned "ablation"? Mine have but tachycardia episodes are so infrequent, I passed.
Suger ?
It is unlikely to be related to any of those, especially since your trials are mixed. It's something else setting off your heart. I don't know a lot about your heart's condition (I have atrial fibrillation in remission after two catheter ablations).

Your heart is now disordered electrically. It has rogue signalling cells in your atria/atrium if only one of them. They fire when they get 'worked up' enough to do so. As the second citation above suggests, the signals have found a re-entrant path and move in a circle-back way to re-enter the atrium endothelium and cause it to beat. It's like double-tapping on a weapon's trigger. Two for the price of one, except that the double-taps keep repeating until the pathway polarizes differently (?) and that signal is broken. Until next time. Note that I am untrained and only know a fair bit about AF, not about SVT or AT. I'm just trying to paint a picture.
Stress is what sets off paroxysmal arrhythmias. It can be poor/lack of sleep, medications, financial woes or relationship problems, illness in others or in yourself, lack of exercise, too much/too intense exercise, dietary problems that might make your gut flora troubled, bowel cramps or gas, bloating, alcohol, non-prescription substances that alter mood or reality, perhaps even Vagus nerve tone. Eating too much at one sitting can cause distension which, in turn, can bring on AF or perhaps SVT/AT if it is the cause of discomfort (stress).
There is help, though. An electrophysiologist (EP) visit is ahead of you, maybe soon, maybe in a year's time, depending on how you respond to various suggested remedies or treatments.
