    Study Notes

    Pulse Rate and Cardiac Output

    • Tachycardia is the medical term for an excessively fast heart rate, defined as a pulse rate greater than 100 beats/min in an adult.
    • Bradycardia is the medical term for a pulse rate less than 60 beats/min in an adult.
    • The pulse rate increases in response to stress due to peripheral vasodilation associated with elevated body temperature, which leads to lowered blood pressure.

    Apical Pulse

    • The apical pulse is located at the apex of the heart and is also known as the point of minimal impulse (PMI).
    • The apical pulse is assessed for clients with known cardiovascular diseases, such as anemia, which is a form of hypovolemia.
    • The apical-radial pulse assessment is commonly indicated for clients with known cardiovascular, pulmonary, and renal diseases.

    Pulse Wave and Cardiac Output

    • The pulse wave represents the volume of blood that enters the veins with each ventricular contraction.
    • Cardiac output represents the forceful or full blood volume that is obliterated only with difficulty and is calculated by multiplying stroke volume (SV) by heart rate (HR) per minute.
    • The formula for calculating cardiac output is SV x HR per minute.

    Pulse Characteristics

    • A pulse rhythm with irregular beats is characterized as arrhythmia or irregular pulse.
    • A pulse that is readily obliterated with pressure from the fingers is termed a bounding pulse.
    • A weak, feeble, or thready pulse is characterized by a forceful or full blood volume that is obliterated only with difficulty.

    Peripheral Pulse

    • A peripheral pulse is a pulse located near the body's periphery, such as in the foot or wrist.
    • Examples of peripheral pulse locations include the radial pulse in the wrist and the tibial pulse in the ankle.

    Factors Affecting Pulse Rate

    • Age: the pulse rate gradually increases overall as age increases.
    • Stress: pulse rate increases in response to stress.
    • Other factors that can affect pulse rate include cardiovascular, pulmonary, and renal diseases.
