OMG!! I have severe neck problems too!! I've never connected that, though. Thanks. Maybe a real symptom of something else.
Yes that sensation had an electric feel to it. All along I thought it was my VT. The cardiologists had no idea at all, and thought it was in my head. Fortunately a neurologist had me undergo an MRI of my neck - it was arthritis in the neck. I was told that certain nerves come out of the cervical spine and go down in to the chest. They were being piched (compressed). Physical therapy help me a lot.
I've had that feeling. Funny, isn't it? I also have checked my pulse during this and felt nothing. I just chalk it up to another one of those weird symptoms I get.
I didn't get any results yet, but I hope they would have not let me leave if they saw anything serious.
Depending on what type of echocardiogram you were having, irregular beats (i.e., afib) would have shown on the monitor. I've heard other people comment on a feeling of vibration, but I don't recall reading anything serious. What were the test results?
