Background and objective Prior studies have suggested that patients with premature ventricular complexes (PVCs) may have an ...

This pressure–volume curve, which describes left ventricular compliance, is normally curvilinear. Furthermore, alterations in left ventricular compliance shift the pressure–volume curve.

Right Ventricular Systolic Pressure (RVSP) is commonly estimated during preoperative Transthoracic Echocardiography (TTE) using the modified Bernoulli equation [RVSP (mmHg) = 4TRV 2 + RAP, where TRV, ...

The relationship between peak isovolumic developed pressure (Pmax) and end-diastolic volume can indicate ventricular contractility. Therefore, we propose a practical method to estimate Pmax from the ...

Ventricular function curves of cardiac output and stroke volume versus left ventricular end-diastolic pressure were obtained during rapid infusion of Tyrode's solution in dogs standing at rest and ...

A 73 year old woman presented with profound central cyanosis and a history of a minor stroke. She had normal heart morphology, normal pulmonary artery pressure, and a normal coronary angiography. A ...

Unlike reservoir and pump functions, in fact, conduit makes little contribution to ventricular stroke volume in the initial stages of DD, but this contribution gains importance in the advanced stages ...

The ultrasound pressure-strain loop (PSL) technique is a non-invasive method of examining myocardial work, which takes into account the effect of cardiac afterload on deformation and combines the ...

Article • Non-invasive method Pressure-strain loop to assess myocardial work The value of using left ventricular pressure-strain loops as a non-invasive way to assess myocardial work was outlined in a ...

Consumer Reports sees whether wrist-cuff blood pressure monitors are accurate. Wrist-cuffs may be a good choice for people who can't use an arm-cuff BP monitor.

Left ventricular myocardial work index (LVMWI) is a novel and noninvasive method for LV work analysis (11). The combination of LV deformation and afterload by constructing an LV pressure-strain loop ...
