Tricuspid valve – The structure that controls blood movement from the heart’s higher right chamber (the correct atrium) into the lower right chamber (the appropriate ventricle). Ventricular tachycardia – An arrhythmia (abnormal heartbeat) within the ventricle characterized by a really quick heartbeat. Tachycardia – Accelerated beating of the center. The heart contracts more than 100,000 times every day as it pushes blood by the blood vessels. This technique is useful in learning patients whose coronary heart and vessels, for numerous causes, are troublesome to assess with standard echocardiography.
