[Monomorphic ventricular tachycardia during the ajmaline test].

Abstract

A 44-year-old male patient admitted with palpitations was diagnosed with tachycardia with wide QRS, but recovered after being treated with amiodarone. The patient's coronary angiography was normal. As the patient's resting ECG was compatible with Brugada type 2, an ajmaline challenge test was scheduled. The infusion procedure was suspended following an observation of type 1 ECG findings in the 4th minute of infusion. Approximately 10-15 seconds later, a monomorphic ventricular tachycardia with a rate of 150 beats/minute developed. In the follow-up, the patient's heartbeat returned spontaneously to the sinus rhythm within 3-4 minutes. Polymorphic ventricular tachycardia or ventricular fibrillation tachyarrhythmias usually result in syncope or sudden cardiac death in cases of Brugada syndrome, while monomorphic tachycardia, as in our case, is rare. Here, we present a rare case of monomorphic ventricular tachycardia, which was observed during the ajmaline challenge test.
