DeWinter T Waves?
The electrocardiogram (ECG) in the figure was obtained from a woman with dyspnea and marked hypertension, but who had no chest pain. How would you interpret this ECG? Should you activate the cath lab?

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.

Flank Pain and ‘Heartburn?’
The electrocardiogram (ECG) in the figure was obtained from a man in his 60s who presented to the emergency department for a suspected kidney stone. The patient also noted some intermittent heartburn in recent weeks. How would you interpret his ECG? Should you activate the cath lab?

Does the Physical Exam Help?
You are given the electrocardiogram (ECG) in the figure and told that the patient is a young man in his 20s who presents with acute dyspnea. The physical exam is remarkable for tachypnea, cyanosis, and clubbing of the extremities. How would you interpret the rhythm? Do the noted physical exam findings help in your assessment of the rhythm?

How Does the 12-Lead Help?
You are given the electrocardiogram (ECG) in the figure without the benefit of any history. How would you interpret this tracing? How does the 12-lead ECG help with interpretation of the rhythm?

Biomarker Enhances Screening for Atrial Fibrillation
A large Swedish population study of screening for atrial fibrillation (AF) in 75-year-old individuals that was enhanced by N-terminal pro-B-type natriuretic peptide (NT-proBNP) stratification did not identify more AF cases or prevent thromboembolic outcomes compared to unscreened control subjects. However, a low NT-proBNP (< 125 ng/L) did identify individuals at low risk for AF and thromboembolic events in whom screening could be safely forfeited.

Look for the Pattern
How would you interpret the two-lead rhythm strip shown in the figure? Hint: Is there a pattern?

An ECG in Disguise?
The electrocardiogram (ECG) in the figure was recorded from an older man following a bradycardic and hypotensive episode. What ECG diagnosis is suggested by this tracing?

The Cath was “Clean!”
The featured electrocardiogram was obtained following successful resuscitation from cardiac arrest. Although echo done soon after showed akinesis of the anterior wall, no significant coronary narrowing was seen on cardiac catheterization. Can you explain? What is this phenomenon called?

How Do the Rhythm and 12-Lead Go Together?
The patient whose electrocardiogram (ECG) is shown presented for care because of chest pain. Looking at this ECG, can you determine why?
