Holter study was immediately performed, which showed 1 premature atrial contraction, 43 premature ventricular contractions, and 5 episodes of ventricular tachycardia (VT) that lasted for 1-3 s each (HR 225-229 bpm, QTc 450 ms) all occurring within a 2-min time frame soon after a single seizure episode (see Figure 2).
