Pulmonary Veins: Where Exactly Do You Measure the A Wave and AR Duration?

I’ve seen it shown both ways, and I’m getting conflicting explanations.” If you’ve asked this yourself, you’re not […]

Coupling is the measure of teamwork between the right ventricle and the pulmonary circulation—how efficiently the RV converts its contraction into blood flow through the lungs.
