Case: A 56-year-old man who revived after ventricular fibrillation was transferred to the emergency center at Kansai Medical University. The blood examination, computed tomography, and cardiac echocardiography at the time admission could not detect the cause of ventricular fibrillation. However, high-performance liquid chromatography revealed mianserin and aripiprazole in his serum. The concent...

Self-terminating ventricular fibrillation was recorded in a 47 year old woman without coronary artery or other structural heart disease. Reperfusion was thought to be responsible for the ventricular fibrillation because the arrhythmia started while the ST segment was returning to the baseline during an episode of silent ischaemia that was probably caused by coronary spasm. This case shows that ...

BACKGROUND Heart failure and stroke are major causes of morbidity and mortality in older people. Angiotensin converting enzyme inhibitors improve symptoms and survival in left ventricular systolic dysfunction. Anticoagulants are effective in stroke prevention in atrial fibrillation with aspirin being a less effective alternative. OBJECTIVES To determine the prevalence of left ventricular syst...

Foot and mouth disease (FMD) is a highly contagious viral disease of cloven-hooved livestock and wildlife results to relatively high mortality in young animals. Despite the numerous reports of FMD-related death in neonates, there is little data available on various aspects of FMD in lambs. This report describes myocarditis associated with FMD in five, one week to three months old lambs. The lam...

Introduction Of the many possible cardiovascular causes of sudden death— arrhythmia, trauma, intracranial vascular catastrophes, and acute thrombosis or embolism affecting the heart or lungs—the present discussion is restricted to the arrhythmic causes and primarily to ventricular fibrillation. Not all episodes of ventricular fibrillation lead to death. As with atrial fibrillation, ventricular ...

Automatic implantable cardioverter-defibrillators (AICDs) were implanted in 378 men and 95 women, mean age 69 +/- 12 years. At 3.6-year follow up, survival was 76% in patients who had an AICD because of cardiac arrest as a result of ventricular fibrillation or ventricular tachycardia not resulting from a transient or reversible cause; 85% in patients who had an AICD because of spontaneous susta...

Defibrillation/cardioversion thresholds were measured in 33 patients undergoing defibrillator implants. Each patient had a 12 cm2 patch placed near the left ventricular apex via a thoracotomy and a 10 cm2 spring lead placed pervenously at the right atrial-superior vena caval junction. Ventricular tachycardia of stable morphology, polymorphic ventricular tachycardia, or ventricular fibrillation ...

Introduction: It has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. This phenomenon is named remote preconditioning of trauma. Since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-...

• In previous papers from this laboratory,' it has been shown that isolated guinea pig and cat hearts perfused with Tyrode solution without substrates undergo a decrease in rate, a decrease in amplitude of the R wave, a lengthening of the P-R interval, ventricular premature contractions, A-V dissociation, and, finally, ventricular fibrillation. The ventricular fibrillation, induced by the lack ...
