Ive got rheumatoid arthritis, hypertension, and Hashimotos. I just had an ECG at a walk-in clinic for a pre-op check-up and it showed non-specific T wave abnormality and possible left atrial enlargement. Can you explain what that means? Should I be worried and see a cardiologist about it?

The non-specific T wave abnormality and possible left atrial enlargement on your ECG could be indicative of various conditions, including cardiac issues such as atrial fibrillation, myocardial ischemia, or structural heart disease. Given your medical history of rheumatoid arthritis, hypertension, and Hashimoto's, it is important to further evaluate these findings. I recommend consulting with a cardiologist for a more detailed assessment and appropriate management. In the meantime, it would be beneficial to monitor your blood pressure regularly and ensure that your rheumatoid arthritis and Hashimoto's are well controlled. If any symptoms such as chest pain, palpitations, or shortness of breath occur, seek immediate medical attention.
