Diastolic dysfunction is a heart condition that happens when there is a “stiffening” of the major pumping chambers of the organ (ventricles). This stiffness gets in the way of the heart’s ability to ...

S indicates systole; d, diastole. Figure 8. Cardiac hemodynamic tracings after valvuloplasty. Left atrial (LA) and ventricular (LV) pressure illustrating improvement in left atrial pressures, and ...

In response to emailed questions, Systole Health CEO and Co-founder Dr. Simin Gharib Lee talked about how her company is addressing this medical need. I started Systole because I kept seeing the ...

The regional speckle area of interest was manually adjusted for optimal tracking results. The GLS was calculated at the point of peak value during systole using a 17-myocardial segment model (17). The ...

Systole is normally the highest pressure point generated. The aortic valve opens, rapid ejection occurs, and the ventricle delivers 66%-75% of its stroke volume. [1] Thereafter, flow velocity ...
