Termination of idiopathic sustained monomorphic ventricular tachycardia by intravenous adenosine in a pregnant woman.
A 34-year-old pregnant woman presented to the emergency department with the complaints of palpitations at 32 weeks gestation. The diagnosis of right ventricular outflow tract ventricular tachycardia (VT) was made. Intravenous 5 mg of metoprolol and 25 mg of diltiazem did not terminate the VT. Ten milligrams of adenosine were administered. Within 10 s of adenosine administration, sustained VT converted to repetitive monomorphic VT and within 30 s to normal sinus rhythm. The mother and the foetus tolerated the medications well. Non-stress test for the assessment of the foetal well-being was normal.
