Rosh Internal Medicine Boost Practice Exam

What heart rate was observed in the patient during the examination?

1. 134 beats per minute

2. 180 beats per minute

3. 160 beats per minute

4. 120 beats per minute

The correct answer is: 180 beats per minute

In this case, the observed heart rate of 180 beats per minute is indicative of a tachyarrhythmia, which is a faster-than-normal heart rate typically seen in conditions such as atrial flutter, atrial fibrillation, or other supraventricular or ventricular tachycardias. A rate this high can lead to inadequate cardiac output, potentially resulting in symptoms such as palpitations, shortness of breath, or even chest pain. When evaluating patients with elevated heart rates, it's important to consider both the context of the patient's symptoms and the clinical setting. Factors such as recent exercise, fever, or stress could also contribute to an increased heart rate. In the context of this examination, a heart rate of 180 is often associated with more acute medical conditions requiring immediate assessment and intervention, contrasting with lower heart rates that might suggest less urgent or chronic issues. Understanding these heart rate ranges aids in the diagnosis and management of various medical conditions, emphasizing the critical importance of heart rate monitoring in patient evaluation.
