Congestive heart failure and disorders of the heart beat.

Cardiovascular disease is the leading cause of death in the United States. Congestive heart failure (CHF) is often the result of many non-fatal heart problems. Many patients who suffer from heart failure die as a result of cardiac dysrhythmias.
