Does Electrode Position Affect the Results of Cardioversion?
A randomized trial of anteroposterior vs. anterolateral electrode positioning for the biphasic energy cardioversion of atrial fibrillation showed the anterolateral positioning is most effective.

Should the Cath Lab Be Activated?
How should one interpret the ECG in the figure? Should the cardiac cath lab be activated on the basis of this ECG?

EDs See More High-Risk Patients with Ventricular Assist Devices
To reduce risks for patients with ventricular assist devices, providers should learn how they work, what complications need to be evaluated, and how to do so. Ensure systems are put in place for providers to care for these patients in an expeditious and effective way.

Post-Exercise Premature Ventricular Contraction, or Aberrancy?
The ECG in the figure is a post-exercise tracing. There are four wider and slightly early occurring beats in the long lead rhythm strips. Are these beats premature ventricular contractions or premature atrial contractions conducted with aberration?

Is This Wellens’ Syndrome?
The ECG in the figure is from a young adult man known to have a bicuspid aortic valve. He presented to the ED following a presyncopal episode. The patient has not experienced chest pain recently. Does this patient have Wellens’ syndrome?

What’s the Best Way to Fix ‘Leaky’ Heart Valves?
Researchers scrutinized common surgical techniques.

Slow, Steady, and Synchronized Wins the Race
In patients with atrial fibrillation and heart failure, definitive rate control via atrioventricular junction ablation and biventricular pacing resulted in a significant reduction in all-cause mortality vs. pharmacologic rate control.

Long-Term Post-TAVR Survival and Permanent Pacemaker Implantation
An analysis of a real-world database revealed 14% of patients undergoing routine transfemoral transcatheter aortic valve replacement required permanent pacemaker implantation within 30 days of the valve procedure. There was no difference in long-term survival between patients who did and did not undergo pacemaker implant.
