Yep, see a cardiologist. PVCs, aberrant signals from the lower chambers of your heart can make it feel like your heart skips a beat, then sometimes comes back with what feels like a very hard beat. It is actually an extra beat that starts in one of your ventricles. A cardiologist can help you figure out if there is something else that needs to be done or ease your mind that there isn't anything to be too concerned about.
All the best and welcome home!
