Atrioventricular Junctional Arrhythmias

  • Atrioventricular junctional arrhythmias, whether bradycardia or tachycardia (rate >100 BPM), abolish atrial transport function and may also be associated with tricuspid or mitral regurgitation. In patients dependent on atrial transport function, such as those with severe diastolic dysfunction, restoration of sinus rhythm is highly desirable. Anticholinergic or sympathomimetics are often ineffective or only increase the rate of AV junctional rhythm.
