    What is a left axis in a ventricular stenosis (VT)?
    A left axis was usually seen in VTs arising near the septum; the more the VT moves laterally, the more “right” or superior the axis will become. In patients with anterior MI, the accuracy of the ECG localization is lower than in patients with inferior MI, probably due to the more extensive myocardial damage.

    The decision to treat patients with OT VT depends on frequency and severity of symptoms. Treatment options include medical therapy vs. catheter ablation. 1. Acute termination of RVOT VT can be achieved by vagal maneuver or adenosine (6 mg up to 24 mg). Intravenous verapamil (10 mg given over 1 min.) is an alternative if the patient has adequate blo...

    Idiopathic ventricular tachycardia in patients with an anatomically normal heart is a distinct entity whose management and prognosis differs from ventricular tachycardia associated with structural heart disease. The tachycardia's QRS morphology on surface electrocardiogram (ECG) predicts the site of origin and is commonly classified as right ventri...

    Outflow tract ventricualr tachycardias (OT VT) comprise a subgroup of idiopathic VT that are predominantly localised in and around the right and left ventricular outflow tracts. OT VT are the most common form of idiopathic VTs and originate, in more than 80%-90% of cases, from the right ventricular outflow tract. They manifest at a relatively early...

    This form of idiopathic VT was first described by Zipes et al. (9) in 1979 with the following characteristics: induction with atrial pacing, RBBB morphology with left axis deviation and occurrence in patients without structural heart disease. In 1981, Belhassen et al. (10) showed that this form of VT could be terminated by verapamil, the fourth ide...

    The long-term prognosis of patients with fascicular VT without structural heart disease is very good. Arrhythmias in patients with sporadic, well-tolerated episodes of idiopathic left ventricular tachycardia may not progress despite absence of pharmacologic therapy. (16) Patients with moderate symptoms can be treated with oral verapamil (120 mg/day...
