Abstract
Bradydysrhythmias encompasses a variety of pathologic slow rhythms including sinus bradycardia, which receives sinus nodal input, as well as junctional and ventricular escape rhythms, which are intrinsically firing from a nidus other than the sinus node. Junctional rhythms are faster and have narrow QRS complexes while ventricular escape rhythms are slower and have wide QRS complexes. Bradycardia may also be secondary to other pathologies such as increased intracranial pressure, i.e., Cushing’s Triad, and digoxin toxicity, which each require their own specific treatment. This chapter concludes with a brief section on cardiac manifestations of digoxin toxicity and the effect that this drug has on an EKG.
