  2. Instantaneous wave-free ratio - Wikipedia

    en.wikipedia.org/wiki/Instantaneous_wave-free_ratio

    The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...

  3. Vectorcardiography - Wikipedia

    en.wikipedia.org/wiki/Vectorcardiography

    Vectorcardiography (VCG) is a method of recording the magnitude and direction of the electrical forces that are generated by the heart by means of a continuous series of vectors that form curving lines around a central point.

  4. Pressure–volume loop analysis in cardiology - Wikipedia

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

    Afterload is the mean tension produced by a chamber of the heart in order to contract. It can also be considered as the ‘load’ that the heart must eject blood against. Afterload is, therefore, a consequence of aortic large vessel compliance, wave reflection, and small vessel resistance (LV afterload) or similar pulmonary artery parameters (RV afterload

  5. Frank–Starling law - Wikipedia

    en.wikipedia.org/wiki/Frank–Starling_law

    Cardiac function curve.In diagrams illustrating the Frank–Starling law of the heart, the y-axis often describes the stroke volume, stroke work, or cardiac output.The x-axis often describes end-diastolic volume, right atrial pressure, or pulmonary capillary wedge pressure.

  6. Cardiac physiology - Wikipedia

    en.wikipedia.org/wiki/Cardiac_physiology

    Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.

  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 ...

  8. Impedance cardiography - Wikipedia

    en.wikipedia.org/wiki/Impedance_cardiography

    Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and used to detect the impedance changes caused by a high-frequency, low ...

  9. Cardiac magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Cardiac_magnetic_resonance...

    Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2]
