The pressure of the blood in the arteries when the heart is filling. It is the lower of two blood pressure measurements (for example, 120/80, where 80 is the diastolic pressure).
Industry:Health care
A condition where blood in the left ventricle leaks back through the mitral valve into the left atrium and can back up into the lungs. The mitral valve normally opens to allow blood to flow into the left ventricle and then closes, preventing blood from backing up into the atrium during the ventricle's contraction.
Industry:Health care
A procedure used in people with severe heart disease who are not candidates for bypass surgery. In this procedure, an incision is made in the chest. The heart is exposed and small holes are drilled through the wall of the heart with a laser. The benefits of TMR have not been proven.
Industry:Health care
A very small amount of radiation is used to produce an image of the structures of the chest (heart, lungs, and bones) on film.
Industry:Health care
Atrial flutter is a regular heart rhythm in which many impulses begin and spread through the atria. The resulting rhythm is organized, but so rapid that the atria are not able to fully empty their contents into the ventricles.

Industry:Health care
An inherited disease that causes thickening of the heart muscle and other changes to the heart that significantly impair its function. Although the disease is rare, IHSS is the single most common cause of sudden cardiac arrest in seemingly healthy young people.
Industry:Health care
A diagnostic study, which uses a small amount of radioactive tracer, injected into the body, and a special camera, which detects the radiation, released by the substance to produce a computer image of the heart. Combined with exercise, the study can help determine if there is adequate blood flow to the heart at rest, as compared with activity.
