  2. Rate pressure product - Wikipedia

    en.wikipedia.org/wiki/Rate_pressure_product

    Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP). It will be a direct indication of the energy demand of the heart and thus a good measure of the energy consumption of the heart. The rate ...

  3. Cardiac function curve - Wikipedia

    en.wikipedia.org/wiki/Cardiac_function_curve

    The pressures where there is a steep relationship lie within the normal range of right atrial pressure (RAP) found in the healthy human during life. This range is about -1 to +2 mmHg . The higher pressures normally occur only in disease , in conditions such as heart failure , where the heart is unable to pump forward all the blood returning to ...

    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.

  5. 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

  6. Coronary perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Coronary_perfusion_pressure

    The heart is supplied by coronary vessels, and therefore CPP is the blood pressure within those vessels. If pressures are too low in the coronary vasculature, then the myocardium risks ischemia (restricted blood flow) with subsequent myocardial infarction or cardiogenic shock .

    When Dr. Oz sat Rachael Ray down for a blood pressure test during a segment of her show, he wasn't entirely pleased with the numbers he saw. In fact, he made her do it again -- and he called her ...

  8. Mean arterial pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_arterial_pressure

    In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.

  9. 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 ...
