Approach to Bradycardia in the ICU
摘要
Bradycardia is defined as a heart rate originating from the sinus node at less than 60 beats per minute. It can be physiological, as seen in well-trained athletes, or pathological, indicating underlying cardiac or systemic issues. While asymptomatic and physiological bradycardia generally does not require intervention, symptomatic bradycardia demands immediate attention to prevent potential catastrophic outcomes such as syncope, heart failure, or sudden cardiac death. New-onset bradycardia, especially when accompanied by symptoms like dizziness, fatigue, or chest pain, often signals underlying cardiac pathology and necessitates prompt evaluation and management [1–3] [Ref: Algorithm 59.1].
