I have also had an ECG and a chest xray with no suspicious results. However, they can now hear a loud murmur so I was sent for an echocardiogram which was yesterday.
I take T3 only and Im now worried that it has damaged my heart. Does anyone else have any experience of T3 and heart murmurs? Ive just read something about low T3 syndrome and hearts but I dont think thats connected.
