Sure. There was inflammation on my heart around those nerves, causing them to cease working. There are three nerves there, that propagate the impulse from your atriums to your ventricles in a controlled manner. When those nerves don't work, some of the impulse still indirectly makes it to the ventricles through the muscle tissue, but it's significantly delayed. So the ventricles beat, but at a significantly slower rate. It seemed to go 2:1 then 3:1, and even 4:1 at times.

I had to get a pacemaker to solve the immediate issue of my heart not beating normally. With the inflammation taken care of a few months later, my nerves eventually started working again and my heart beats normally enough. They aren't 100%, but they're probably good enough that the pacemaker isn't necessary anymore.
