2. 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 ...

3. Heart failure with preserved ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with...

   Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.

4. Cardiac contractility modulation - Wikipedia

   The patients were characterized by a disease severity of NYHA class III and a left ventricular ejection fraction of ≥ 25%. [ 1 ] [ 16 ] Although studies on cardiac contractility modulation therapy have focused on patients with a normal QRS duration (i.e. ≤ 120 ms), it is possible to use the therapy in patients who meet the treatment ...

5. Cardiac resynchronization therapy - Wikipedia

   en.wikipedia.org/wiki/Cardiac_resynchronization...

   The key indication for CRT is left bundle branch block (LBBB) of the heart, a cardiac abnormality leading to delayed left ventricular contraction. LBBB causes a QRS prolongation of ≥120 ms on the electrocardiogram, contributing to poor left ventricular coordination and reduced systolic function, thereby reduced ejection fraction (<35%). This ...

6. Left ventricular mass - Wikipedia

   en.wikipedia.org/wiki/Left_ventricular_mass

   LVM increases withe ageing, though ageing related remodeling of the left ventricle's geometry can lead to a discordancy between CT and echocardiographic based measurements of LVM. [3] Published normal ranges for LVMi are 49–115 g/m 2 for men and 43–95 g/m 2 for women. [1] [4] left ventricular hypertrophy (LVH) is defined as an abnormal ...

7. Cardiac ventriculography - Wikipedia

   en.wikipedia.org/wiki/Cardiac_ventriculography

   test cardiac function in the right, or left ventricle. Cardiac ventriculography is a medical imaging test used to determine a person's heart function in the right, or left ventricle . [ 1 ] Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped.
