How long should you measure a patients pulse if ifs irregular?

If a patient's pulse is irregular, it should be measured for a full minute to accurately assess the heart rate and identify any potential arrhythmias. This allows for a more reliable average of the beats per minute and helps in determining the nature of the irregularity. If the pulse is regular, a 30-second count multiplied by two may suffice, but with irregular rhythms, a complete minute is essential.
