Experiences with TRT and Atrial Fibrillation (AFib)?

[YiL]

Hey everyone,


I’m a TRT user here on the forum, and I’ve been on testosterone replacement therapy (started on 2x75mg and dropped to 2x60mg) for a while now (dec 2025). Recently, I’ve experienced two significant episodes of atrial fibrillation (AFib) since starting TRT, which has me a bit concerned. I’m wondering if any of you have come across similar issues or have knowledge about potential links between TRT and AFib.


Has anyone else on TRT dealt with AFib or heart rhythm problems? What were your experiences, and did you find any ways to manage it? I’d love to hear your thoughts, insights, or any studies/articles you’ve seen on this topic. Let’s brainstorm together—maybe we can share some useful info!


Thanks in advance for your input. Appreciate the community here.

How did you determine Afib was occurring? I’ve dealt with anxiety for years and I don’t use meds to combat it as I don’t liked feeling doped, While going low carb a few months ago got some pretty bad anxiety and a few occurrences of palpitations and skipped beats. Got an echo performed and a holster monitor for a 48hr window, No afib detected and normal sinus rhythm found minus a few PCVs. I was very concerned as the palpitations scared me, to the point I went to the ER for the first time ever! Better safe than sorry though. That got the ball rolling for the aforementioned testing and future cardiac follow up!

Afib has a few unique properties, Usually you will have both an erratic rate and rhythm. Some people report RHR upwards of 150 BPM with a very erratic beat pattern. This is something that won’t always present on a EKG if it’s transient. That’s why an echo and holter monitor should be the next steps. The echo will you a good idea if there is anything structural wise going on with your heart. The holter will detect all beats, HR, arrhythmia if present, as well a journal of all perceived irregularities. Make sure to make note of any occurrences and activities happening when it occurred.

So if you haven’t already you absolutely want to get checked out asap. If you get another feeling of Afib or detect elevated HR last longer than an hour it may be a good idea to visit the ER. Regardless of what’s found a follow up with cardiology is paramount.

Wish you the best sir, please take care of yourself and keep us posted on any results pertaining the condition.
