  2. Stroke volume - Wikipedia

    en.wikipedia.org/wiki/Stroke_volume

    In cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from the ventricle per beat. Stroke volume is calculated using measurements of ventricle volumes from an echocardiogram and subtracting the volume of the blood in the ventricle at the end of a beat (called end-systolic volume [note 1]) from the volume of blood just prior to the beat (called end-diastolic volume).

  3. 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 ...

  4. Cardiac output - Wikipedia

    en.wikipedia.org/wiki/Cardiac_output

    Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...

    en.wikipedia.org/wiki/End-systolic_volume

    End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole. ESV is the lowest volume of blood in the ventricle at any point in the cardiac cycle. The main factors that affect the end-systolic volume are afterload and the contractility of the heart.

    The researchers measured heart function using thoracic impedance cardiography, a noninvasive method of assessing cardiac output and stroke volume. They also measured blood flow in the smaller ...

  8. Velocity time integral - Wikipedia

    en.wikipedia.org/wiki/Velocity_time_integral

    Velocity Time Integral is a clinical Doppler ultrasound measurement of blood flow, equivalent to the area under the velocity time curve. The product of VTI (cm/stroke) and the cross sectional area of a valve (cm2) yields a stroke volume (cm3/stroke), which can be used to calculate cardiac output.

    About 13% — roughly 3,600 participants — had either a heart attack or stroke, had surgery to fix a narrowed or blocked artery, or died from heart disease over the 30-year follow-up period.
