Final answer:
An abnormal electrical pattern prior to the QRS complexes and an increased frequency between them usually indicate an increased heart rate (pulse). This data should be included in additional ECG strips for thorough analysis. (Option 1).
Step-by-step explanation:
When analyzing an electrocardiogram (ECG), noting an abnormal electrical pattern prior to the QRS complexes indicates an anomaly in the cardiac cycle.
An increased frequency between the QRS complexes suggests a faster electrical cycle within the heart. In response to the question, one would therefore expect an increase in heart rate (pulse) as a direct consequence of this observation.
This is because the frequency of QRS complexes correlates with the number of beats per minute; an increased frequency signifies more heartbeats in a given time.
If this was found in preliminary findings, it should be reflected in the additional strips to provide a comprehensive view of the heart's rhythm for further analysis and diagnosis. (Option 1).
