Abstract
We are reporting a case of acquired complete heart block and long QT interval (a dispersion of repolarization that leads to polymorphic ventricular tachycardia) that has presented with loss of conscious and proved to be due to torsade de pointes. The patient responded well to cardiac pacing and beta blocker therapy. The association of complete acquired heart block and long QT interval is quite rare.
