The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs. The right ventricle is one of the heart’s four chambers. It is located in the ...

Left ventricular end-diastolic volume is the amount of blood in the heart’s left ventricle just before the heart contracts. While the right ventricle also has an end-diastolic volume, it’s the value ...

MIT engineers have developed a robotic replica of the heart's right ventricle, which mimics the beating and blood-pumping action of live hearts. The robo-ventricle combines real heart tissue with ...

DEAR DR. ROACH: What’s the difference between atrial fibrillation and premature ventricular contractions, aka PVCs (extra heartbeats)? -- M. ANSWER: Both AFib and PVCs are rhythm disturbances of the ...
