I Know I Have A Heart Condition And I Have

I know i have a heart condition and I have a cardiologist. I want to know the medical term for my condition as I enter REM where my heart slows down too fast and stops for about two beats and return to a normal REM heart rate of about 45.

It took them about two months to figure it was the condition. They had a electrial specialist to come up with the diagnosis. They say 1 in 10 people have the condition and it is not life threatening.
