Belhassen ventricular tachycardia: a case study.

Years of palpitations and a heart rate of 213 beats per minute

Belhassen tachycardia is the most common idiopathic ventricular tachycardia arising from the left ventricle, classically characterized by a right bundle branch block and left axis deviation. Vigilance for Belhassen tachycardia is essential as intravenous verapamil has proven to be highly efficacious for treating symptomatic patients with this underlying arrhythmia.

Deterioration of ventricular tachycardia to ventricular fibrillation after rapid intravenous administration of magnesium sulfate.

We report the case of a patient who had development of ventricular fibrillation following rapid intravenous administration of magnesium sulfate (2 g over 5 s) for treatment of sustained monomorphic ventricular tachycardia. Initial slowing of the tachycardia was followed by gradual widening of QRS complexes and electrical alternans, leading to ventricular fibrillation within 3 min of magnesium a...

Response of recurrent sustained ventricular tachycardia to verapamil.

A 28-year-old man is described with no demonstrable organic heart disease and recurrent paroxysmal attacks of sustained ventricular tachycardia. Lignocaine and ajmaline failed to terminate the first attack but a bolus infection of verapamil succeeded. This drug was subsequently successful on six more occasions. During electrophysiological study of the eighth attack, slow intravenous administrat...

ECG of the month. Idiopathic ventricular tachycardia with a left bundle branch block morphology and right axis deviation.

Unusual manifestations of arrhythmogenic right ventricular dysplasia as ventricular fibrillation, atrial paralysis, and hypoexcitable right ventricle.

Ventricular fibrillation occurred in an apparently healthy 19 year old man. The results of non-invasive and invasive studies suggested right ventricular dysplasia. Electrophysiological studies showed atrial paralysis, hypoexcitability of multiple areas of the right ventricle, and inducible poorly tolerated ventricular tachycardia.
