The narrow complex tachycardias (NCTs) are defined by the presence in a 12-lead electrocardiogram (ECG) of a QRS complex duration less than 120ms and a heart rate greater than 100 beats per minute; those are typically of supraventricular origin, although rarely narrow complex ventricular tachycardias have been reported in the literature. As some studies document, to diagnose correctly the NCTs is an arduous exercise because sometimes those have similar presentation on the ECG. In this paper, we have reviewed the physiopathological, clinical, and ECG findings of all known supraventricular tachycardias and, in order to reduce the possible diagnostic errors on the ECG, we have proposed a quick and accurate diagnostic algorithm for the differential diagnosis of NCTs...

Multifocal atrial tachycardia is typically seen in elderly patients with severe illnesses, most commonly COPD. The mechanism of the arrhythmia may be delayed afterdepolarizations leading to triggered activity, but this has not been firmly established. The initial treatment of multifocal atrial tachycardia should include supportive measures and aggressive reversal of precipitating causes. Since multifocal atrial tachycardia is commonly a secondary phenomenon, the role for antiarrhythmic therapy is unclear. Metoprolol, magnesium, and verapamil have been evaluated in a few treatment studies, and may have a role in the treatment of multifocal atrial tachycardia...

A 31-year-old male smoker with diabetes mellitus presented to the emergency department with intermittent, exertional chest pain of 4 days' duration. Electrocardiography performed on arrival (Panel A) revealed anterolateral T-wave inversions with biphasic lateral T waves, which raised concern about..
