What term refers to a rhythm that alternates between periods of normal heartbeats and abnormal beats?

The term that refers to a rhythm alternating between periods of normal heartbeats and abnormal beats is arrhythmia. Arrhythmia encompasses a variety of conditions where the heart beats irregularly, too quickly, or too slowly, resulting in a loss of the heart's normal rhythm. This can manifest in many patterns, including episodes of normal beats interspersed with abnormal ones.

Understanding arrhythmias is crucial for monitor technicians, as these irregularities can signify serious cardiac issues that require immediate attention. Monitoring the rhythm can help identify when an arrhythmia occurs, assessing its type and significance for patient care. This term accurately encompasses the broader spectrum of heart rhythm disturbances, effectively capturing the essence of the described rhythm.
