Is a History of Palpitations Useful for Detecting Atrial Fibrillation?
An analysis of the utility of implanted loop recorders to detect subclinical atrial fibrillation in high-risk individuals showed that among common arrhythmia-compatible symptoms, only palpitation was predictive of discovering episodes of atrial fibrillation.

Why Is There Group Beating?
The ECG in the figure was obtained from a 40-year-old man with an irregular heartbeat. How would one interpret this rhythm?

Giving the Cold Shoulder to Drug Therapy for Atrial Fibrillation
In two randomized trials published simultaneously, cryoballoon ablation proved superior to drug therapy for prevention of arrhythmia recurrence in patients with paroxysmal atrial fibrillation.

Why Does This WCT Change Its Shape?
Imagine there was no history for the ECG shown in the figure. How would one interpret this tracing?

Left Ventricular Size, Function Predictors of Outcomes in Chronic Aortic Regurgitation
In a large cohort of asymptomatic patients with hemodynamically significant chronic aortic regurgitation, volumetric left ventricular size and function measurements were equally discriminant in identifying patients at higher risk for mortality vs. traditional linear measurements.

Rhythm vs. Rate Control for Atrial Fibrillation Patients: The Controversy Continues
Early use of rhythm control in patients with atrial fibrillation and high cardiovascular risk appears to improve cardiovascular outcomes compared to usual care.
-
Another Affirmation for Rhythm Control in Atrial Fibrillation
A rhythm control strategy implemented less than one year after atrial fibrillation diagnosis was associated with significant reduction in adverse cardiovascular outcomes when compared to usual care.

What Is the Cause of This Regular WCT?
The ECG in the figure was obtained from an older woman who presented with hypotension. What is the rhythm?

The Tactics and Tools to Manage Pediatric Heart Failure
Fortunately, pediatric heart failure is a rare occurrence, but early diagnosis, aggressive management, and timely transfer to a facility capable of advanced cardiac support are essential to optimize the outcome of each child. The authors review the early recognition of a child in heart failure and also discuss an approach to troubleshooting and recognizing complications associated with a ventricular assist device.

How Can This Patient Be Stable?
The ECG in the figure was obtained from a young adult who presented to the emergency department with palpitations, but who otherwise was hemodynamically stable. What is the diagnosis?
