Patient's Query

Hi doctor,

Can you please review my ECG? I am on long-term Azithromycin and Minocycline for Lyme disease.

Answered by Dr. Isaac Gana

Hello,

Welcome to icliniq.com.

I have gone through your ECG result (attachment removed to protect patient identity), and I can see evidence of a second degree AV block (atrioventricular block), which is a common finding amongst patients with Lyme's disease. Since you have already been placed on antibiotics, the ECG will clear up and become normal in weeks. There is no need to worry. Please make sure you complete all the drugs prescribed. Take care.

Patient's Query

Hi doctor,

Thank you for your reply. I have been on antibiotics for four weeks now. I have chronic Lyme disease. Should I be concerned that I have a second degree AV block? Also, a few months ago, I had Doxycycline for four weeks as it is the standard treatment. Could the second degree AV block be due to Azithromycin?

Answered by Dr. Isaac Gana

Hello,

Welcome to icliniq.com.

The AV block is not caused by the Azithromycin but instead caused by the Lyme disease itself due to some inflammatory process that occurs in the heart as a result of the Lyme organisms in the heart tissue. In my experience of dealing with patients, normally antibiotics therapy is three to four weeks and ECG symptoms cleared up in a maximum of six weeks. If you develop symptoms like that of flu, palpitations, shortness of breath or appearance of rashes, then please go to the hospital as you might not be responding to treatment. But in the absence of symptoms, there is no cause for worry. You can repeat the ECG test after three weeks to see the change in ECG. Hopefully, it should have resolved by then. Thank you. Take care.

Same symptoms don't mean you have the same problem. Consult a doctor now!
