How to ignore belligerent PVC's(heart palpitations) when trying to sleep?

Have you ever agreed to let someone periodically punch you in the chest while you were trying to sleep? No? Of course not, no one in their right mind would. Unfortunately I have been enduring similar circumstances non-stop for the past two years, and have been given no say in the matter.

It is very difficult to sleep when a large thump shakes my body every fifteen seconds. Even after two years, it is unnerving and I doubt I will ever get used to it. There must be a way to cope with it while I’m trying to sleep, however, as the sleepless nights are beginning to take a toll on my health and my social life.
