What does the term "bradycardia" imply about a patient's heart rate?

Bradycardia is defined as a slower than normal heart rate, specifically one that is less than 60 beats per minute. This condition can occur for various reasons, including increased vagal tone, certain medications, or underlying health conditions like heart disease. In adults, a heart rate under 60 beats per minute can reduce the efficiency of the heart's ability to pump blood, potentially leading to decreased perfusion and symptoms such as fatigue, dizziness, or even syncope in some cases. Recognizing bradycardia is crucial for paramedics as it may require immediate interventions, especially if the patient presents with accompanying symptoms or if their heart rate drops significantly below this threshold.
