  2. Blood pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Blood_pressure_measurement

    A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...

  3. Pulse pressure - Wikipedia

    en.wikipedia.org/wiki/Pulse_pressure

    A pulse pressure is considered abnormally low if it is less than 25% of the systolic value. [2] If the pulse pressure is extremely low, i.e. 25 mmHg or less, it may indicate low stroke volume, as in congestive heart failure. [3] The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.

    en.wikipedia.org/wiki/Pulse

    In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...

    Zone 1 Adjuster = 50 bpm Zone 2 Adjuster = 40 bpm Zone 3 Adjuster = 30 bpm Zone 4 Adjuster = 20 bpm Zone 5 Adjuster = 10 bpm. Example for someone with a HR max of 180: Zone 1 (easy exercise): 180 − 50 ± 5 → 125 − 135 bpm Zone 4 (tough exercise): 180 − 20 ± 5 → 155 − 165 bpm

  7. Cardiac conduction system - Wikipedia

    en.wikipedia.org/wiki/Cardiac_conduction_system

    [2] The conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG. Dysfunction of the conduction system can cause irregular heart rhythms including rhythms that are too fast or too slow.

    The first pulse closest to the wrist is the cun (inch, 寸) position, the second guan (gate, 關), and the third pulse position furthest away from the wrist is the chi (foot, 尺). There are two main systems of diagnostic interpretation of pulse findings utilised in the Chinese medicine system.
