Trigger-induced atrial fibrillation for the hospitalist: a review

Atrial fibrillation (AF) is a common arrhythmia that a hospitalist may encounter. It is known to occur transiently or in response to specific triggers (trigger-induced AF), which presents a challenge to clinicians, especially when attempting to ascertain if it warrants assessment of recurrence risk and long-term management. The management of trigger-induced AF is an emerging area of study. In this review, we discuss questions that a hospitalist should consider and address in the management of trigger-induced AF. We discuss recommendations regarding anticoagulation along with rate and rhythm control strategies, in addition to the importance of long-term surveillance. We also examine the evidence base outlined by the most recent AF guidelines from the United States and Europe. Further investigation with randomized clinical trials is warranted to better understand the epidemiology and management of trigger-induced AF, as well as its long-term effects and care.
