Final answer:
The patient's heart rate cannot be determined from the narrative provided as there is no numerical value given for the heart rate.
Step-by-step explanation:
The heart rate of the patient cannot be determined from the given narrative. Although symptoms like chest pain (CP), shortness of breath (SOB), and the fact that atropine was administered suggest a heart-related issue, the exact heart rate (HR) is not provided in the narrative. For an adult, a normal resting heart rate (HR) is typically 60-100 beats per minute (bpm). A lower rate would indicate bradycardia, and a higher rate would suggest tachycardia. In the absence of a numerical HR value in the narrative, we are unable to ascertain whether the patient's heart rate falls under bradycardia, normal range, or tachycardia, despite the symptomatic treatment given.
