What does an irregular pulse indicate?

An irregular pulse indicates unevenly spaced beats, which signifies that the heart is not maintaining a consistent rhythm. This can be caused by various factors, such as stress, heart disease, or other underlying medical conditions.

Understanding the significance of an irregular pulse is crucial for healthcare providers, as it can be a symptom of more serious issues, prompting further evaluation and potential intervention. In contrast, options that describe consistent heartbeat rhythms or perfectly spaced beats do not align with the concept of irregularity, and normal heart function would typically exhibit a regular pulse pattern. Thus, the correct answer accurately reflects the implications of measuring an irregular pulse.
