How Is An EKG Done?

Hi. 63-year-old obese female. I had an EKG at my cardiologist s office this week. (He is following me for mild aortic stenosis.) When the doctor looked at the result he said this EKG looked markedly different from my previous ones and wants me to have another stress test. Question: I have never had an EKG where I wasn t asked to remove my bra and wrist watch. This time, I asked the nurse if my underwire bra would affect the test; she said no. I forgot to ask about the watch (battery-operated). I was stupid enough to forget to mention the bra and watch to the doctor when he mentioned the different EKG. I also think my legs were crossed at the ankle during the test. I guess I come across as an idiot here, but should I call the doctor s office and ask if another EKG would be prudent before going in for another expensive nuclear stress test? Thanks!

General Surgeon 's  Response
Hello,

As per my clinical experience, a stable aortic stenosis over a period of time does not reveal a great difference during follow up consultation with EKG unless there are additional features of:
- Repeated syncopal episodes
- Bounding pulses in the neck
- Water hammer pulse (Corrigan pulse)
- Brui ausculatation in the carotid regions
- Breathlessness on exertion
- Chest discomfort with palpitation

A significant reason for the EKG alteration seems to be in concern with battery operated wrist watch and wired bra , which will definitely change the electrical axis of the heart chambers with peripheral leads tracing.

It is strongly recommended to get repeat EKG with wrist watch and bra removal to avoid such issues and save money of expensive nuclear stress test.

Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Bhagyesh V. Patel, General Surgeon
