Your heartbeat can be heard as a “Lub-dub” sound.

The first heart sound (Lub) is caused by the mitral and tricuspid valves closing.

The second heart sound (dub) is caused by the aortic and pulmonic valves closing.

Heart Murmurs

• Sounds like a swishing sound with the Lub dub sound.

• Caused by a valve not closing tightly or a hole in the heart

Cardiac Arrest

• When circulation completely stops to the rest of the blood

• There is no pulse because the heart is not pumping blood

• A person becomes unconscious because oxygen is not delivered to the brain

• Drug overdosing can cause someone to go into cardiac arrest

Heart Attacks

• This is different than cardiac arrest• A heart attack occurs when a blood vessel

becomes blocked and interrupts blood flow to the heart, causing heart muscle to die.

• a fatty material called plaque (plak) builds up over many years on the inside walls of the coronary arteries

Enlarged Heart

• Chicago Bears player, Gaines Adams died last weekend from an enlarged heart

• Enlarged heart tells you that the heart is being overworked.

• This can mean there is something wrong with the heart anatomically

• Or there is too much physical pressure on the heart

Heart Disease

• Heart Disease is the leading cause of death in the United States. Every 34 seconds, someone dies of heart disease in the US. Heart disease is a term used to describe many diseases that affect the heart.

Coronary Artery Disease

• Disease that causes clogged arteries.

• Symptoms: Chest pain and heart attacks

Cardiovascular disease

• A number of diseases that affect the heart or blood vessels. These include diabetes, high blood pressure and high cholesterol.

Congestive Heart Failure

• A condition that can result from any structural or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body.

• Leads to the heart and body's failure.

Heart Bypass Surgery is used to treat

patients with chest pain and prevent heart attacks. In this procedure, part of a blood vessel from another part of the body is stitched in to “bypass” the clogged artery and take blood to the heart.
