THE commonest cause of death following coronary occlusion, certainly in the experimental animal if not in the human being, is ventricular fibrillation. We wish to report the relative effect of chronic ischemia alone and of a myocardial revascularization procedure on the susceptibility of the heart to ventricular fibrillation. Two questions in this regard that might be answered by the measuremen...

Three patients with ischaemic heart disease died suddenly while being monitored with an ambulatory tape recorder. Two had terminal ventricular fibrillation initiated by paired bidirectional ventricular ectopic beats against a background of scattered ectopic activity; both had had ventricular tachycardia during routine treadmill exercise testing in the week before death. The third patient develo...

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-rep...

Atrial fibrillation was induced during an electrophysiology study in 10 patients with the Wolff-Parkinson-White (WPW) syndrome, after determination of baseline properties of the accessory atrioventricular (AV) connection; intravenous propranolol (0.2 mg/kg) was then administered. Atrial fibrillation terminated during the drug infusion in three patients, allowing determination of propranolol's e...

The Wolff-Parkinson-White syndrome can rarely present with pre-excited atrial fibrillation. In this condition the short refractory period of the accessory pathway can lead to rapid atrioventricular conduction. There is then a danger that at high heart rates the irregular broad complex tachycardia that results can deteriorate into ventricular fibrillation. The initial management of patients pres...

The ever-present hazard in patient monitoring is electrocution resulting in ventricular fibrillation. Fire and explosion hazards are possibilities but seem to be very remote. Iatrogenic electrocution can occur when: (a) more than one piece of electrical equipment is connected to the patient. (b) the distal end of an intracardiac electrode is handled. (c) pericardiocentesis is carried out with E...

The multicenter randomized study of the Gruppo Italiano per lo Studio della Streptochinasi nell'Infarto Miocardico has provided the opportunity to analyze the impact of thrombolytic treatment on secondary ventricular fibrillation incidence in a large population of patients (11,712) with acute myocardial infarction. A reduction of about 20%So in the frequency of secondary ventricular fibrillatio...

Ventricular fibrillation seen just after declamping of the aorta is an undesirable condition causing myocardial injury. To return to normal rhythm, often internal shocks are applied. But defibrillation itself can also contribute to myocardial injury. So prevention of fibrillation is more important than treatment. 236 patients undergoing coronary artery by-pass surgery were included in this retr...

Capillary ultrainicroeleetrodes were inserted into ventriculaimuscle fibers of dogs in ventricular fibrillation nnd action potentials obtained were compared with deflection.? of unipolar direct lead, adjoining; bipolar direct lead or other electrocardiograms taken simultaneously. In most stages of ventricular fibrillation neither synchronism nor any other regular time relationship could be foun...

Cardiac rhythm abnormality is a common finding in patients with leptospirosis. Relative bradycardia, atrial fibrillation, flutter and ventricular premature beats are the arrhythmias seen In present case, patient presented septic shock had fibrillation. Further evaluation revealed hypokalemic acute kidney injury severe metabolic acidosis. The fibrillation reverted to sinus after correction of hy...
