there are many treatment modalities available to acutely terminate incessant ventricular tachycardia with variable success rates, but some cases tend to prove refractory to all of them. we report a 59-year-old woman presenting with incessant ventricular tachycardia. echocardiography revealed a large true apical aneurysm and severe left ventricular dysfunction. the arrhythmia was controlled in t...

cardiac involvement infrequently occurs in hypopituitarism, and lethal cardiac arrhythmias are rarely reported. we present a middle age female who died as a consequence of refractory ventricular arrhythmia whose medical history and previous laboratory investigation were consistent with hypopituitarism. we conclude that hypopituitarism may lead to electrocardiographic changes and malignant ventr...

Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

Background & Aims: This study was carried out to assess the effect of opium addiction on the incidence of different types of arrhythmias after acute myocardial infarction (AMI). Methods: The study population consisted of 200 patients with first AMI admitted within 6 hours of the onset of chest pain to the coronary care units (CCU) of two hospitals affiliated to Kerman University of Medical Scie...

objective: in ventricular arrhythmias, due to their free radical scavenging action, antioxidant agents are usually used in the treatment of cardiovascular disease. since stress is considered as risk factor for increased mortality by causing malignant arrhythmias, the study was designed to evaluate the cardioprotective effects of ellagic acid (ea) on cacl2-induced arrhythmias in rat stress model...

Tachycardia is common in the pediatric age group. The most commonly seen arrhythmias in children are sinus tachycardia. However, supraventricular tachycardia is the most common tachyarrhythmia that necessitates treatment. Ventricular tachycardia is rare in healthy children but may be associated with sudden cardiac death.  The important risk factors that predispose children for arrhythmias inclu...

We analyzed the morphology and rate of ventricular tachycardia induced by programmed cardiac stimulation in 18 patients with recurrent sustained ventricular tachycardia who had only one type of ventricular tachycardia during spontaneous episodes. In nine of 18 patients, we induced only one type of ventricular tachycardia, with a morphology and rate similar to those noted during spontaneous vent...

BACKGROUND Many physicians believe that electrocardiographic characteristics of nonsustained ventricular tachycardia correlate with the risk for sudden death in survivors of myocardial infarction. Sustained ventricular tachycardia induced by programmed electrical stimulation has also been shown to predict sudden death. OBJECTIVE To determine whether electrocardiographic characteristics of spo...

We analyzed the morphology and rate of ventricular tachycardia induced by programmed cardiac stimulation in 18 patients with recurrent sustained ventricular tachycardia who had only one type of ventricular tachycardia during spontaneous episodes. In nine of 18 patients, we induced only one type of ventricular tachycardia, with a morphology and rate similar to those noted during spontaneous vent...
