The heart is a hollow, muscular organ in vertebrates responsible for pumping blood through the blood vessels by repeated, rhythmic contractions, or a similar structure in annelids, mollusks, and arthropods.
Hi - Great place here. Hope to hear from people. I am panicked to say the least. I just found out I have second degree type 2 heart block - the more serious kind. The outcome from reading on the web is a pacemaker. The good news is my resting heart rate is good at 74 - but the doctor said that during a 72 hour Holter I wore last week, there were some instances of the second degree heart block rhythm.
I am on a low priority list - two months - to see a cardiologist. Very panicked as I have two very young boys and a home to support.
