Step-by-step explanation:
If the heart rates from the last two minutes are not within 5 beats per minute (bpm) of each other, the best course of action is to continue monitoring the heart rates. This could be a normal variation in heart rate due to external factors such as stress or physical activity. It's important to observe the heart rates over a longer period of time to establish a trend and to look for any symptoms that may be associated with abnormal heart rates.
