Bradyarrhythmia
Results:
Bradycardia: DDx
Key Points Common Offenders: Beta-blockers, calcium channel blockers, and digoxin often top the list of medication-induced bradycardia. High Vagal Tone or AV Block can arise from structural heart disease, ischemia,…
Wide QRS Bradyarrhythmia: DDx
Key Point Wide QRS bradycardias usually reflect infranodal conduction disease (His–Purkinje or below), making them much more dangerous than narrow QRS bradycardias. These rhythms often lead to hemodynamic instability and…
