I have had Tachycardia all my life. I've had heart palpitations since I was about 13. I finally had them checked thorougly by a cardiologist when I was 15 and was told everything was fine.
The meds I'm on are synthroid for hypothyroid, adderall xr for adhd, and of course, T. A few weeks into being on T, I had increased heart palpitations and it would feel like it would stop, then start again, or beat irregularly. I've had EKGs done and they were pronounced fine, but I didn't have any palpitations while they did it. Along with the heart palpitations I had symptoms of hyperthyroidism. So to experiement, I stopped taking my thyroid med. I haven't taken it for 3 days. The palpitations stopped, then came back today. I'm not sure what is causing this. Could be stress or anxiety, or simply that I have a high natural heart rate. I'm hoping it's not related to starting T....maybe starting T changed my thyroid, causing it to go hyper? I'm not sure. If it's due to the T, that's too bad. Cause I'm taking it no matter what. I'm afraid to mention this to my doc cause I'm afraid he'll decide it's complications from T and discontinue me. So, advice, insight?
