A 62-year-old man presented to the emergency room with palpitations and dyspnea. The patient had a history of kidney disease and bicuspid aortic valve disease, with class III/IV heart failure and left ventricular dilatation and dysfunction (ejection fraction, 40%) but no history of palpitations, dizziness, or syncope. Physical examination on admission revealed blood pressure of 130/80 mmHg and no overt signs of heart failure. The admission ECG showed regular, wide-QRS tachycardia (Figure 1). Sinus rhythm was restored with electrical cardioversion (Figure 2).What is the most mechanism in this patient?

  • 1.

    Monomorphic ventricular tachycardia due to myocardial reentry.

  • 2.

    Monomorphic ventricular tachycardia due to bundle branch reentry.

  • 3.

    Nodal reentrant tachycardia with right bundle branch block.

  • 4.

    Preexcited tachycardia.
