I'm a bit concerned about my heart rate. It's usually around 96, but it goes up to 120 when I walk. I don't have any other symptoms and I've had a thyroid test, ECG, and echo done, all of which came back normal. The only thing on the ECG was sinus tachycardia. I did have mild Covid last April. Should I be worried about this, or will my heart rate settle down on its own over time?

Sinus tachycardia is a common condition where the heart rate is elevated but the heart rhythm is normal. Since your thyroid, ECG, and echo results are normal, and considering your history of mild COVID-19 last year, your elevated heart rate may be due to post-viral effects. In most cases, sinus tachycardia resolves on its own as the body recovers from the viral illness. To help manage your heart rate, you can try to reduce stress, stay hydrated, and ensure you are getting adequate rest. If your symptoms persist or worsen, you can consider taking a beta-blocker medication like Metoprolol at a low dose of 25mg once daily to help control your heart rate. However, it is important to consult with your doctor before starting any new medication. Monitoring your heart rate regularly and following up with your healthcare provider for further evaluation is recommended.
