In adults, what pulse rate defines bradycardia?

  1. Less than 60 beats/min

  2. Less than 50 beats/min

  3. Less than 40 beats/min

  4. Less than 30 beats/min

The correct answer is: Less than 60 beats/min

Bradycardia in adults is defined as a pulse rate that is less than 60 beats per minute. This threshold is significant because a heart rate below this value can indicate various underlying health issues, such as heart block, increased vagal tone, or effects from medications. Monitoring pulse rate is crucial in emergency medicine, as bradycardia can lead to inadequate blood flow and oxygen delivery to the body's tissues. Recognizing it early allows for timely intervention, which may range from observation to administering medications or pacing in severe cases. Understanding this definition and its implications in patient assessment is vital for EMTs handling emergencies.
