Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...

Right atrium: This upper chamber receives unoxygenated blood from the body and ejects it through the tricuspid valve to the right ventricle.; Right ventricle: This lower chamber receives blood ...

Pacemakers regulate the right atrium and right ventricle to maintain a good heart rate and keep the atrium and ventricle working together. This is called AV synchrony.

Learn about the anatomy of the heart and how its chambers, valves, and vessels work together to maintain effective blood circulation throughout the body to sustain life.

X-ray study showed enlargement of the right ventricle and left atrium. On clinical grounds she was thought to have significant mitral regurgitation as well as stenosis.

A fourth heart sound indicates a stiff left ventricle, which may be seen in chronic hypertension (high blood pressure), ...

Diffuse sickness of the atrium can cause very rapid and chaotic signals in the atrium resulting in atrial fibrillation or somewhat more organized rhythms called atrial flutter. Damage to the ventricle ...

The bicuspid valve separates the left atrium and left ventricle and prevents back flow of blood from the ventricle to the atrium. It likewise opens due to a build-up of pressure, this time in the ...

Double inlet left ventricle (DILV) is a very rare condition in which the heart chambers and valves are malformed. It occurs in about 5-10 of every 100 000 babies born alive.

The TEER procedure is highly recommended for patients who are considered high surgical risk due to pre-existing issues like ...

In this case, intrinsic activity is sensed in both the atrium and the ventricle, inhibiting the output from the pulse generator. Pacemakers are classified by a series of four letters ( Table I).
