    Pulse rhythm

    Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
    Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
