What Does "left-axis Deviation" In An EKG Indicate?

Posted on Thu, 5 Feb 2015

Question: My husband had an EKG done, it showed a left-axis deviation. He has previously been diagnosed with a left bundle block, although the current doctor says he does not see the left bundle block.

Does this increase his risk for heart attack?

We are considering following up with a cardiologist.

Hi and thank you for asking!

I read your query and understood your concerns.

I would like to have an image of your ECG so I could give an exact opinion. However as a general rule it doesn't necessarily increase the incidence of heart attack.

I apso advice to contact soon your cardiologist.

Brief Answer:
Your Husband ECG is abnormal, go to ER if he doesn't feel ok....

Detailed Answer:
Hi back,

I checked by myself your husband ECG and I can confirm a left axis deviation. But what concerns me most is that i see a "Q vave" in inferior leads (may be a sign of prior infarction) and a poor R vave progression i V1 to V4 (may be sign of ischemia).

As i said above these findings may be signs of prior miocardial ischemia and infarction and other examinations are essential to find out the exact diagnosis. If your husband isn't feeling ok, or has chest pain, dyspnea etc. he should go immediately to Er. Otherwise he can wait for cardiologist appointment.

If he was my patient i would recommend to do the following examinations:
- Cardiac Echo.
- Stress test (Nuclear cardiac stress test).
- Blood works and cardiac enzymes.
- Angiography.

Hope you will find this information helpful!
Wish you and your husband health!

Thank you Dr. Shehu. I did make an appointment for him next week. Your information is very helpful! We had a 52 year old friend die from a sudden massive heart attack two weeks ago. She had no prior warning signs or health problems. We are definitely going to follow up and I'll take your recommendations to the cardiologist here.
Thank you again, XXXX
