If the pulse rhythm is irregular, how long should you count to assess it accurately?

Explanation:
When the pulse rhythm is irregular, you need a length of time that captures variation in the beat-to-beat intervals. Irregular rhythms aren’t evenly spaced, so a short count might miss clusters or pauses and give an inaccurate rate. Counting for a full minute records every beat that occurs in that period, letting you calculate the true beats per minute and observe the irregularity. Short counts like 15 or 30 seconds aren’t reliable for irregular rhythms, and a 120-second count is longer than needed. So, count for a full minute to assess it accurately.
