Intensive Monitoring for Asymptomatic Atrial Fibrillation Did Not Prevent Strokes
Screening with an implantable loop recorder resulted in dramatically higher rates of atrial fibrillation detection and ensuing anticoagulation, but without a significant decrease in risk of stroke or systemic embolism by six years of follow-up.

Is This Ventricular Tachycardia?
The ECG in the figure was obtained from an elderly man with chest pain and shortness of breath. Is the rhythm ventricular tachycardia?

No Harm in a Morning Cup of Joe
Habitual coffee consumption was inversely associated with a lower risk of cardiac arrythmia.

Coffee Consumption and Tachyarrhythmias
An analysis demonstrated an inverse association of coffee consumption and cardiac arrhythmias, which was not altered by genetic variations in caffeine metabolism, age, or sex. -
Is AV Block Complete?
The dual lead rhythm strip in the figure was obtained from an elderly patient with syncope. Is there AV dissociation? Is there complete AV block? This is a challenging tracing because a different diagnosis is suggested by the first five beats in the rhythm strip, compared to the last four beats. -
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. -
Age Drives Stroke Risk in Atrial Fibrillation
Among patients with newly diagnosed atrial fibrillation age 66-74 years without other CHA2DS2-VASc risk factors for thromboembolism, the older they are in this age range, the more likely they are to experience a stroke. -
What Form of Heart Block?
Does the rhythm in the figure represent Mobitz II second-degree AV block, complete AV block, or Wenckebach? Does the patient need a pacemaker? -
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?
