The study found that 24 percent of the patients had been misdiagnosed: 22 patients previously diagnosed with epilepsy were found to have nonepileptic seizures, and four patients previously diagnosed with nonepileptic seizures were found to have epileptic seizures.
The purpose of valves is to prevent back flow of blood. In other words, it ensures that blood flows only in one direction . An atrioventricular (AV) valve is a valve located in the heart between the atria and the ventricles. In the right side of the heart, the AV valve is called the tricuspid valve . On the left side of the heart, the AV valve is called the mitral valve .
Atrioventricular Valves Function. Av Valves Function. There are four valves, pulmonary, mitrial,tricuspid and aortic in the heart. There is an AV(atrioventricular) node within the heart. When the heart is in diastole, at rest 1/10th second, an electrical impulse begins to emanate from the sinoatrial node. Atrial systole is bought about by the impulse for the sinoatrial node spreading over the artia.
