Ectopic Heartbeats: 27 F from UK asks about ectopic heartbeats when I laugh hard. Not certain what u mean by ectopic beats but heart beats differently every beat based on signals coming & going from brain 2 heart. These change every millisec 2 be certain blood flow to brain etc is constant. So speed and strength change each beat. Laughing may provoke Valsalva reflex which changes rate/strength of beat. Google it.
