Bradyarrhythmia

Typical nodal escapes occurring during sinus bradyarrhythmia, and subsequent to a nodal premature systole with retrograde A-V and aberrant ventricular conduction.

It is our hypothesis that, since bradyarrhythmia seldom resolves spontaneously, the early decrease in survival represents the deaths of many patients with untreated bradycardia.

The term bradyarrhythmia should be reserved for any heart rhythm <60 bpm. Bradyarrhythmias may be associated with symptoms such as dizziness, near-syncope or syncope, congestive heart failure, exercise intolerance, fatigue, or a confusion that improves with resolution of the bradycardia.
