Heart rhythm problems, called arrhythmias, occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly. Heart arrhythmias are often harmless – in fact, most people have occasional, irregular heartbeats. However, some heart arrhythmias may trigger bothersome or even life-threatening symptoms.

Congestive heart failure occurs when your heart can't pump enough oxygen-rich blood to meet your body's needs. The condition is termed "congestive" because poorly pumped blood can back up and congest in the lungs, liver, abdomen and lower extremities.

Coronary artery disease occurs when the arteries that supply blood to your heart become narrowed or blocked by fatty, cholesterol-containing deposits called plaques in a condition called athersclerosis. The blockage reduces the amount of blood and oxygen reaching your heart which can damage your heart muscles.
Coronary artery disease often develops slowly over the course of many years, so it may go unnoticed until it triggers a major episode. Eventually, reduced blood flow can cause chest pain (angina), shortness of breath, or other symptoms. A complete blockage can cause a heart attack.
