    Tachycardia comes from the Greek words tachys (rapid or accelerated) and kardia (of the heart). Tachycardia typically refers to a heart rate that exceeds the normal range for a resting heart rate (heart rate in an inactive or sleeping individual). It can be dangerous depending on the speed and type of rhythm.

    tachyarrhythmia means any disturbance of the heart's rhythm, regular or irregular, resulting in a rate over 100 beats per minute. (tachy means rapid or speed; arrhythmia means variation from the normal rhythm especially of the heart beat).

    Pressure overload: When mitral valve is leaky, the blood will regurgitate into upper chamber causing pressure overload in the left atrium. This will cause enlargement of the left atrium.

    When aortic valve is leaky, the blood will regurgitate into lower chamber causing pressure overload in the left ventricle. This will cause enlargement of the left ventricle.

    Volume overload: The excess fluid, primarily salt and water, builds up in various locations in the body and leads to an increase in weight, swelling in the legs and arms (peripheral edema), and/or fluid in the abdomen (ascites). Eventually, the fluid enters the air spaces in the lungs, reduces the amount of oxygen that can enter the blood, and causes shortness of breath (dyspnea). Fluid can also collect in the lungs when lying down at night, possibly making nighttime breathing and sleeping difficult (paroxysmal nocturnal dyspnea). Congestive heart failure is the most common result of fluid overload. Drugs that relieve fluid overload is called diuretics,
