Global left ventricle hypokinesis refers to a condition where the entire left ventricle of the heart is not pumping blood as well as it is supposed to. Global means that it is the entire left ventricle, not just a certain area, and hypokinesis means diminished muscular function, as noted by e-Echocardiography.
The human heart is made up of four different chambers: the left and right atrium and the left and right ventricle. These chambers periodically fill up with blood and then pump the blood out into the arteries. The heart is a muscle, and the muscle must expand and contract to pump blood. As opposed to the right ventricle, the left ventricle has especially thick, strong walls to pump blood from the heart through the arteries to all extremities throughout the body.
Ventricular hypokinesis can happen to either the right or the left ventricle. In general, it just means the muscle tissue does not contract properly. Ventricle hypokinesis can either be global or regional, and mild to severe. Typically, ventricle hypokinesis is a sign of coronary artery disease, heart failure, or a heart attack.
Patients with global left ventricle hypokinesis often experience dizziness, fatigue, irregular heartbeat, and other symptoms that occur with poor blood circulation. Treatments for this condition vary based on what is causing the poor muscle function.
