When to see a doctor. Arrhythmias may cause you to feel premature or extra heartbeats, or you may feel that your heart is racing or beating too slowly.

In CHF (congestive heart failure), the heart muscle becomes weaker. When the heart muscle is weakened, it is less forceful in pumping blood throughout the body. Less blood moves out of the heart.The body has several ways to try to keep the same amount of blood flow moving.any symptoms of CHF are linked to the congestion that develops as fluid backs up into the lungs and leaks into the tissues. Other symptoms occur because not enough oxygen-rich blood gets to the body. The effects of heart failure on the body depend on which side of the heart is affected.
