Hello doctor,

I went to the ER for shortness of breath. I suffer from panic disorder and hypochondria. My doctor did an EKG and released me and told me it was benign. I saw my QTc was 470. Is this correct? She told me there was a benign ST elevation. I am so nervous. Please help me. Is this EKG normal? Do I have a prolonged QT?

Hello,

Welcome to icliniq.com.

No, it is not a long QT (attachment removed to protect patient identity). Manually, QTc fine. There are S waves in lateral leads suggestive of some conduction delay and early stages of RBBB (right bundle branch block), which can also be seen normally in some individuals and more common in athletes. So, at present, there are minor changes in ECG which are fine to have and does not suggest any particular abnormalities. However, you may need echo if clinically indicated like having consistent shortness of breath on exertion rather than panic attack, or any other symptoms suggestive of heart disease. So, overall should be considered as benign.

Thank you doctor,

I have had two echos in the past two years for RBBB. Is that what this EKG is suggesting? Is that what the ST elevation is from?

Hi,

Welcome back to icliniq.com.

That is great. Yes, there are RBBB changes and nonsignificant ST elevation due to RBBB only. This elevation is not at all significant.
