Hi Ion, Im Dana and Welcome to Connect. I'm sorry that this issue of feeling your heartbeat is probably distracting. As for the Bump that will probably always be there as mine was also slightly protruding from my chest. As for the heartbeat I know at times I could feel mine also and it seemed to be a position issue. May I ask why you have a pacemaker? For me I had a virus that affected my Heart and it got enlarged so for me it seemed if I layed on my left side I could feel it beat. I always figured it was that my heart was enlarged and pushing against something that made me feel it. So maybe investigate different positions and even try lifting the head of your bed to an incline position. Let me know how you make out I'm sure others would love to hear about options also. Part of why I like connect is helping each other solve things maybe others who are in similar situations may be experiencing.
Have a blessed day
