AV valves are the atrioventricular valves which prevent the back flow of blood from the ventricles (lower chambers of the heart) when they contract.

Regional wall motion abnormality (RWMA) on an echocardiogram Regional wall motion abnormality on an echocardiogram means that a region of the heart muscle is not contracting as it normally

HUTT is short form for head up tilt test. A tilt table and ECG monitoring equipment are necessary for conducting the test.

AIVR is short for accelerated idioventricular rhythm. When the normal pacemaker of the heart (sinus node) slows down, subsidiary pacemakers can take over.

Cardiac CT scan image at the level of the bifurcation of the main pulmonary artery (MPA) into right pulmonary artery (RPA) and left pulmonary artery (LPA).

TMT is short for treadmill (device used for exercise testing) test. The subject walks on a motorized belt, the speed and gradient of which can be adjusted.

When heart contracts, blood is pushed into the blood vessels through the aorta from the left ventricle. This increases the blood pressure at that time.

EVOLVO study found that remote monitoring of defibrillators is useful in terms of reducing ER visits, total health care usage and better quality of care.

Dyeless angiography is possible with magnetic resonance imaging where the signals from the moving hydrogen particles in blood give the image.

Many of the cardiac arrhythmias can be worsened with psychological stress.
