Heart and Blood Pressure Disorders

Heart disease is a term for any type of disorder that affects the heart.  It includes blood vessel disorders, heart rhythm problems, and heart defects. Blood pressure is the pressure that blood exerts on the artery walls during and in-between heart beats.  High blood pressure (hypertension) is when the pressure on the artery walls is high.  Low blood pressure (hypotension) can cause dizziness and fainting.
