Answer

Answer

The etiology and management of torsade are, in general, quite different from those of garden-variety VT. In particular, the use of group IA antidysrhythmic drugs, which tend to prolong the QT interval, can have disastrous consequences in torsade. Differentiating between these entities, therefore, is critically important.

For more information, go to Ventricular Tachycardia.

See Can't-Miss ECG Findings, Life-Threatening Conditions: Slideshow, a Critical Images slideshow, to help recognize the conditions shown in various tracings.
