The electrical impulse travels through the atrium and reaches the atrioventricular node (AV node), which is the normal connection to the ventricles, the bottom chambers of the heart that pump blood to ...

Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen. The newly oxygen-rich ...

Medically reviewed by Jeffrey S. Lander, MD Congestive heart failure (CHF) and heart failure are the same thing. Both terms ...

The lower chambers are known as the left and right ventricles. The two on top, which are the ones involved in the arrhythmia you have been diagnosed with, are called the left and right atrium.

Trinity Health Muskegon recently achieved a significant milestone by successfully implanting AVEIR DR, the world’s first dual-chamber leadless pacemaker system designed to effectively treat abnormal ...

The normal mitral valve permits unrestricted antegrade diastolic flow from the left atrium to the left ventricle (LV) and effectively seals off the atrium from the ventricle during LV systole ...

This area is sufficient to allow a great deal of blood to flow from the left atrium (LA) to the left ventricle. When any disease process decreases the mitral valve area, mitral stenosis (MS ...

The mitral valve allows blood to flow from the left atrium of the heart into the left ventricle. Mitral regurgitation occurs when the mitral valve leaks blood back into the left atrium.
