  2. Cardiac stress test - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stress_test

    A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.

  3. Cold pressor test - Wikipedia

    en.wikipedia.org/wiki/Cold_pressor_test

    The cold pressor test is a cardiovascular test performed by immersing the hand into an ice water container, usually for one minute, and measuring changes in blood pressure and heart rate. These changes relate to vascular response and pulse excitability. Some research suggests that the outcome of the cold pressor test can help to predict ...

    en.wikipedia.org/wiki/Stress_testing

    A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate. [16]

  5. Pathophysiology of hypertension - Wikipedia

    en.wikipedia.org/.../Pathophysiology_of_hypertension

    Exaggerated stress responses may contribute to the increased incidence of hypertension in this group. [35] For patients having hypertension, higher heart rate variability (HRV) is a risk factor for atrial fibrillation. [36] Resistant hypertension can be treated by electrically stimulating the baroreflex with a pacemaker-like device. [37]

  6. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    The haemodynamic response is rapid delivery of blood to active neuronal tissue. Complications in this response arise in acute coronary syndromes and pulmonary arterial hypertension. These complications lead to a change in the regulation of blood flow to the brain, and in turn the amount of glucose and oxygen that is supplied to neurons, which ...

  7. Hypertension - Wikipedia

    en.wikipedia.org/wiki/Hypertension

    Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [ 1 ]

  8. Baroreflex - Wikipedia

    en.wikipedia.org/wiki/Baroreflex

    Bainbridge reflex: In response to stretching of the right atrium wall, heart rate increases, lowering venous blood pressure. Antidiuretic hormone: The hypothalamus detects the extracellular fluid hyperosmolality and the posterior pituitary gland secretes antidiuretic hormone to increase water reabsorption in the collecting duct.

  9. 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.
