Key result
Pharmacologic therapy and pacing manage symptomatic bradyarrhythmias based on acuity and underlying etiology.
Why the study?
Bradyarrhythmias encompass a range of physiologic and pathologic conditions requiring tailored management based on symptom severity and underlying causes.
Management of bradyarrhythmias depends on symptom severity, underlying causes, and risk of progression, utilizing pharmacologic therapy or pacing for unstable cases.
Highlights need for rapid assessment in bradycardia; level 5 evidence leaves optimal protocols open for study.
Bradyarrhythmias are common clinical findings consisting of physiologic and pathologic conditions (sinus node dysfunction and atrioventricular [AV] conduction disturbances). Bradyarrhythmias can be benign, requiring no treatment; however, acute unstable bradycardia can lead to cardiac arrest. In patients with confirmed or suspected bradycardia, a thorough history and physical examination should include possible causes of sinoatrial node dysfunction or AV block. Management of bradycardia is based on the severity of symptoms, the underlying causes, presence of potentially reversible causes, presence of adverse signs, and risk of progression to asystole. Pharmacologic therapy and/or pacing are used to manage unstable or symptomatic bradyarrhythmias.

Shu‐Fen Wung (2016) conducted a review in Bradyarrhythmias. Pharmacologic therapy and/or pacing was evaluated. Pharmacologic therapy and pacing are utilized to manage unstable or symptomatic bradyarrhythmias, with treatment decisions based on symptom severity and underlying causes.
