Abstract
The surface electrocardiogram (ECG) holds many clues with regard to the etiology of bradycardia and site of atrioventricular (AV) block. Bedside maneuvers may prove helpful in cases of 2:1 AV block or situations where the data is not all concordant. Wenckebach conduction may occur in any region of the heart, and there are nonpathologic mimickers of Mobitz II AV block as well. The surface ECG may aid in the inference of etiology for better than expected or slowed rather than blocked AV conduction. Sinus node dysfunction may present in several forms and often accompanies other conduction system disease. On occasion invasive studies may be required to help elucidate the mechanism of bradycardia.
