  2. Pulsus alternans - Wikipedia

    en.wikipedia.org/wiki/Pulsus_alternans

    Pulsus alternans is diagnosed by first palpating the radial or femoral arteries, feeling for a regular rhythm but alternating strong and weak pulses. Next, a blood pressure cuff is used to confirm the finding: the cuff is elevated past systolic pressure and then slowly lowered cuff towards the systolic level.

  3. Pulse - Wikipedia

    en.wikipedia.org/wiki/Pulse

    Pulse deficit: difference in the heart rate by direct cardiac ausculation and by palpation of the peripheral arterial pulse rate when in atrial fibrillation (AF). Pulsus alternans: an ominous medical sign that indicates progressive systolic heart failure. To trained fingertips, the examiner notes a pattern of a strong pulse followed by a weak ...

  4. Pulse pressure - Wikipedia

    en.wikipedia.org/wiki/Pulse_pressure

    Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.

  5. Peripheral Arterial Tone - Wikipedia

    en.wikipedia.org/wiki/Peripheral_Arterial_Tone

    The PAT signal is a form of pulse wave amplitude measured by incorporating both a unified pressure field and a specific isosbestic wavelength.Applying a uniform pressure field around the measured surface releases arterial wall motion restriction, magnifies the dynamic range of the recorded signal, and prevents the distention of the veins distal to the site of pressure application.

  6. Vital signs - Wikipedia

    en.wikipedia.org/wiki/Vital_signs

    The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...

  7. Pulsus paradoxus - Wikipedia

    en.wikipedia.org/wiki/Pulsus_paradoxus

    Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure (a drop more than 10 mmHg) and pulse wave amplitude during inspiration. Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure.

  8. Clinical electrophysiology - Wikipedia

    en.wikipedia.org/wiki/Clinical_electrophysiology

    Clinical electrophysiology is the application of electrophysiology principles to medicine. The two main branches of this discipline are electrotherapy and electrophysiologic testing (EEG, electromyography, etc.) Clinical electrophysiology can be utilized in the study and treatment of various physiological conditions, and most notably in clinical cardiac electrophysiology.

  9. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    Cardiac arrhythmia is often first detected by simple but nonspecific means: auscultation of the heartbeat with a stethoscope, or feeling for peripheral pulses. These cannot usually diagnose specific arrhythmia but can give a general indication of the heart rate and whether it is regular or irregular.
