2. Pressure–volume loop analysis in cardiology - Wikipedia

   en.wikipedia.org/wiki/Pressure–volume_loop...

   Real-time left ventricular (LV) pressure–volume loops provide a framework for understanding cardiac mechanics in experimental animals and humans. Such loops can be generated by real-time measurement of pressure and volume within the left ventricle.

   Blood pressure. Aortic pressure; Ventricular pressure; Atrial pressure; Ventricular volume; Electrocardiogram; Arterial flow (optional) Heart sounds (optional) The Wiggers diagram clearly illustrates the coordinated variation of these values as the heart beats, assisting one in understanding the entire cardiac cycle.

4. Pressure–volume diagram - Wikipedia

   en.wikipedia.org/wiki/Pressure–volume_diagram

   During this phase, pressure continues to fall. The mitral valve and aortic valve are both closed again so volume is constant. At point D pressure falls below the atrial pressure and the mitral valve opens, initiating ventricular filling. DA is the diastolic filling period. Blood flows from the left atrium to the left ventricle.

5. Frank–Starling law - Wikipedia

   en.wikipedia.org/wiki/Frank–Starling_law

   The stretch on the individual cell, caused by ventricular filling, determines the sarcomere length of the fibres. Therefore the force (pressure) generated by the cardiac muscle fibres is related to the end-diastolic volume of the left and right ventricles as determined by complexities of the force-sarcomere length relationship. [11] [7] [6]

6. Pressure–volume loop experiments - Wikipedia

   en.wikipedia.org/wiki/Pressure–volume_loop...

   Left ventricular PV loops are considered to be the gold standard for hemodynamic assessment and are widely used in research to evaluate cardiac performance. While it has long been possible to measure pressure in real time from the left ventricle, measuring the volume was technically more difficult.

7. Ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Ejection_fraction

   Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
