Bradycardia

What Is Bradycardia?

Bradycardia is a medical condition characterized by a heart rate that is slower than normal, typically defined as fewer than 60 beats per minute in adults. While it can occur as a physiological adaptation in well-conditioned athletes, it may also indicate significant underlying health issues, such as myocardial ischemia or electrolyte imbalances, that require clinical evaluation. Not to be confused with tachycardia, which refers to an elevated heart rate, bradycardia necessitates careful assessment within the context of patient care protocols, such as those outlined in NIMS and ICS frameworks.

Why Bradycardia Matters on the Fireground

Identifying bradycardia is crucial for emergency medical responders, as it can be a marker for serious conditions that may require prompt intervention. Timely recognition and assessment can facilitate appropriate treatment strategies and improve patient outcomes. Clear definitions improve handoffs, documentation clarity, and team alignment when multiple providers must prioritize tasks under time pressure.
