What is the best treatment for a patient with second degree AV block Mobitz Type II?

The appropriate treatment for a patient experiencing second-degree AV block, specifically Mobitz Type II, is transvenous pacing. This form of pacing is indicated because Mobitz Type II typically occurs due to a blockage in the conduction system that can lead to complete heart block (third-degree AV block). Unlike Mobitz Type I (Wenckebach), Mobitz Type II does not show progressive lengthening of the PR interval before a blocked beat, and this makes it less stable; it can result in sudden complete heart block, thus necessitating immediate intervention.

Transvenous pacing offers a direct way to ensure that the heart maintains an adequate rate and rhythm while also bypassing the abnormal conduction through the AV node. This treatment is critical as Mobitz Type II can lead to significant hemodynamic instability due to the risk of sudden cardiac arrest or severe bradycardia, where the heart rate may drop dangerously low.

Other treatments listed, such as amiodarone, epinephrine, and aspirin, do not provide the immediate benefit needed in cases of Mobitz Type II AV block. Amiodarone is typically used for certain arrhythmias and does not directly address the conduction problem. Epinephrine may assist in cases of severe brady
