Digital devices for heart rhythm monitoring in atrial fibrillation patients scheduled for elective electrical cardioversion.

Introduction And Objectives: Management in recent-onset atrial fibrillation (AF) is to achieve sinus rhythm (SR) by cardioversion (CV). However, frequently SR is spontaneously restored, making scheduled admission unnecessary and causing misutilization of healthcare resources. Emerging medical technology allows accurate heart rhythm monitoring.

Integrated dilator-needle transseptal crossing device in atrial fibrillation cryoballoon ablation procedures.

Introduction: In cryoballoon ablation (CBA) procedures, transseptal access (TSA) is generally achieved using a standard sheath and needle system that is exchanged for the cryoballoon delivery sheath and dilator over a long wire. Sheath exchange has been related with air embolic events. Recently, an integrated dilator-needle system assembled to the cryoballoon sheath was introduced.

Solving difficulties in transseptal sheath crossing: The technique.

The technique is a simple and safe maneuver that can help to solve difficulties in challenging transseptal sheath crossing for atrial fibrillation cryoablation procedures.

Left bundle branch pacing in alternating bundle branch block.

We present a case of symptomatic intermittent AV block showing during monitorization alternating bundle branch block. Presuming a high need of pacing, conduction system pacing was considered a more physiological alternative in this patient. Left bundle branch pacing restored a stable atrioventricular synchrony with a paced QRS complex similar to the native one and might be a good alternative in these cases.
