Background: Cardiac failure is the major lethal consequence of aluminum phosphide (AlP) poisoning. This study was designed to determine the frequency of cardiac arrhythmias in patients with AlP poisoning. Methods: In this prospective cross-sectional study, patients with definitive history of AlP poisoning treated at emergency department of Allied Hospital Faisalabad, Faisalabad, Pakistan, from ...

An unusual case of ventricular arrhythmia is reported with electrocardiograms showing complete attacks of ventricular tachycardia, ventricular flutter and ventricular fibrillation. The etiology is unknown. Large doses of quinidine, to the point of toxicity, seemed to halt the arrhythmia but did not prevent its recurrence. Ephedrine was given with resulting immediate improvement and no recurrenc...

Electrophysiologic studies (EPS) were performed in 155 patients with hypertrophic cardiomyopathy (HCM). Indications for EPS were cardiac arrest in 22 patients, syncope in 55 patients, presyncope in 37 patients, asymptomatic ventricular tachycardia (VT) in 24 patients, palpitations in 10 patients, and a strong family history of sudden cardiac death in seven patients. Thirty-five (23%) patients h...

Objective(s): Ventricular arrhythmias including ventricular tachycardia (VT) and ventricular fibrillation (VF) are the most important causes of mortality rate. Gallic acid (GA) has beneficial effects on cardiovascular diseases. The aim of this study was to evaluate the effects of GA on electrophysiological parameters such as QRS complex, heart rate (HR), PR interval pa...

A protocol for programmed ventricular stimulation is described in which the effect of increasing stimulation current on ventricular refractoriness and arrhythmia induction was specifically examined. The protocol was evaluated prospectively in 70 patients undergoing electrophysiological study for documented or suspected ventricular arrhythmias. Programmed electrical stimulation was performed at ...

OBJECTIVE To examine the relation between ventricular dysfunction and late clinical arrhythmia in adults who underwent the Mustard procedure for transposition of the great arteries. DESIGN Observational study based on periodic outpatient assessment of biventricular function. SETTING Tertiary referral centre. INTERVENTIONS Analysis of data from 12 lead ECGs, echocardiography, exercise radi...
