To help you better understand my heart, my EKG will show the peak then a small peak attached to the main one on the right side. What it’s doing is showing the delay of the signal going thru the secondary pathways. I have to watch what medications I take because I can’t take something that will slow my heartbeat up anymore or my heart will probably stop. My heart’s wearing out but it’s still trying to work and keep me alive. Can’t ask anymore of a heart that should have killed me as a child. If it bothers you so much, if you have a good insurance, get an appointment with a Electro Cardiologist and let them test you, that’s what I did and I highly recommend you do too, to give you pease of mind.
