Exceptional Seizure-Like Presentation of Torsades De Pointes

Figures

• 

  Figure 1. The ECG demonstrates a premature ventricular complex (PVC) occurring on the descending limb of the T wave, consistent with the R-on-T phenomenon.

• 

  Figure 2. The ECG demonstrates a premature ventricular contraction (PVC) occurring on the descending limb of the T wave (R-on-T phenomenon). This triggers a polymorphic ventricular tachycardia consistent with torsades de pointes, characterized by twisting QRS complexes with varying amplitude and morphology.

• 

  Figure 3. ECG demonstrates non-sustained polymorphic ventricular tachycardia (VT).

• 

  Figure 4. ECG demonstrates premature ventricular contraction (PVC) with R-on-T phenomenon leading to non-sustained ventricular tachycardia (VT) in the form of torsades de pointes.
