I'm just wondering, what are the dangers of high pulse rate. My usual pulse when resting is between 85-95.. but sometimes it dips down nearer to normal around 70. But thats rare. Sometimes when I'm walking around my house I feel a pounding in my chest and it feels like my heart is in the bottom of my throat. When I check it then .. its anywhere from 120-135. Is that dangerous? I'm really overweight... but I can't lose.. I"ve tried for years. What do I do?????
