Arrhythmia Recurrence After Catheter Ablation of Atrial Fibrillation
An integrated nationwide medical and pharmacy claims database analysis of patients with new atrial fibrillation undergoing catheter ablation as first-line therapy has shown that 17% of patients required repeat ablation for recurrent atrial fibrillation despite the frequent use of antiarrhythmic drugs.

Arrhythmias in the Holiday Heart Syndrome
A small study of continuous electrocardiogram and breath alcohol concentration in young volunteers during acute excessive alcohol consumption has shown that heart rate and ventricular premature beats increased during the drinking period. During recovery (six to 19 hours), significant arrhythmias such as atrial fibrillation occured in 5% of the subjects. The observed changes in heart rate variability and breath alcohol concentration suggest that these effects are the result of increased sympathetic nervous system activity associated with excess blood alcohol concentrations.

Reviewing Pediatric Arrhythmias
Although pediatric arrhythmias are uncommon, it is essential to recognize which ones require diagnostic evaluation and therapy and which ones do not. Frequently, there are normal variations on pediatric ECGs that do not require a significant evaluation, but recognizing critical arrhythmias in pediatric patients is a must-know for providers.

Where Are the P Waves?
The ECG in the figure was obtained from a previously healthy young woman with “palpitations.” How would one interpret this two-lead rhythm strip? Is there a conduction disorder?

Smoking Cessation After Atrial Fibrillation Diagnosis Could Lower Dementia Risk
A cohort study of patients with atrial fibrillation (AF) in South Korea revealed patients who stopped smoking after AF diagnosis were at lower risk for developing dementia than those who continued smoking.

A Growing Body of Evidence Supports Left Bundle Branch Pacing
Several late-breaking trials presented at the annual Scientific Sessions of the Heart Rhythm Society add to the data for left bundle branch pacing as an alternative to biventricular pacing for cardiac resynchronization therapy.

Anticoagulation Therapy in Octogenarians with Atrial Fibrillation
In patients age 80 years and older with atrial fibrillation who were not considered for oral anticoagulants because of serious comorbidities, one-quarter of the recommended daily dose of edoxaban was superior to placebo for preventing thromboembolic events.

Gastrointestinal Bleeding on Anticoagulants: Predicting Colorectal Cancer in Afib Patients
A large Danish registry study showed that in atrial fibrillation patients on oral anticoagulants and who experience a lower gastrointestinal bleed, the incidence of a subsequent diagnosis of colorectal cancer is significantly higher than in those without bleeding.

How Fast Can You Recognize This Rhythm?
How might the reader interpret the two-lead rhythm strip shown in the figure? Is there AV block? If so, is this complete (i.e., third-degree) AV block?

Gastrointestinal Bleeding on Anticoagulants: Predicting Colorectal Cancer in Afib Patients
A large Danish registry study showed that in atrial fibrillation patients on oral anticoagulants and who experience a lower gastrointestinal bleed (LGIB), the incidence of a subsequent diagnosis of colorectal cancer is significantly higher than in those without a LGIB.
