PALS Chapter 7: Bradycardia Practice Test 2025

Last Updated on May 10, 2025

Pediatric Advanced Life Support PALS Chapter 7: Bradycardia Practice Test 2025 Questions Answers Quiz. Bradycardia is a heart rate slower than usual for a child’s age. Bradycardia in children and infants should be evaluated, but not all bradycardia needs to be medically managed.

Intervention is required when bradycardia is symptomatic and compromises cardiovascular function. This commonly means that the heart is beating too slowly to maintain blood pressure, causing shock, poor tissue perfusion, and/or a change in mental status.

Symptomatic bradycardia may cause several signs and symptoms, including low blood pressure, pulmonary edema/congestion, abnormal rhythm, chest discomfort, shortness of breath, lightheadedness, confusion, and/or syncope. Bradycardia most commonly becomes symptomatic when it is new to the person (acute heart rate slowing).
