Having a blood vessel do that isn't going to affect your heartbeat. Your heart will still beat the same whether the vessel is so called sputtering or not. BUT....when there are vibrations with pauses you would think that your heartbeat would have a pause too. I have tried to see if that was so but could not feel a skip in heartbeat that coincided with the pause. I think that is something that needs to be done in a controlled setting with more sophisticated equipment. But no, the vibrations do NOT interfere with the regularity of the heartbeat because I wore a monitor for a month once to see if it would pick up anything. It wasn't a Holter monitor. I wore one of those too and had to write down when I had palpitations. With this different monitor, I pushed a button everytime I had palpitations. I would have the vibrations at night and push the button thinking it may pick it up. It didn't. My cardiologist said the vibrations have nothing to do with nor do they interfere with the heartbeat. The monitor did not pick up ANY vibrations at night. Even though I had to push a button, that was only to draw attention to that particular time and incident. The whole months recordings were looked at.
