Im 30 years old, weight 95km length 1.8m. Sometimes especially at night I feel my hart rate go up, and then feels like my hart stops.  It hurts a bid and Im getting a little short of breath.  Also when I eat especially during the day, after I ate I feel weird and like my stomach and chest are compressed, I also get headaches.
U got to get an echocardiography done. You might require a Holder test also. Meet a cardiologist and get yourself evaluated once.
