Incidence of arrhythmias in the dog following transthoracic ventricular defibrillation with unidirectional rectangular stimuli.
نویسندگان
چکیده
The incidence of the various types of arrhythmia induced by defibrillation in anesthetized dogs that had had continuous ventricular fibrillation for 30 seconds was studied as a function of the current strength and the duration of the unidirectional rectangular pulse used to terminate the fibrillation. Shocks at 10, 20, 40, 80, and 100 amp with durations in the range of 80 fisec through 64 msec were used. At any given energy level the incidence of induced arrhythmias was much larger for the 40-, 80-, and 100-amp shocks than for the 10and 20-amp shocks. At 10 and 20 amp, the incidence of induced arrhythmias increased with increasing energy content. Premature ventricular contractions were observed at nearly all levels of energy and current, in contrast to other types of arrhythmias that appear to be strongly related to energy content or current amplitude or both.

متن کاملThe Effect of Opium Addiction on Cardiac Arrhythmia after Acute Myocardial Infarction
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...
متن کاملEllagic acid improved arrhythmias induced by CaCL2 in the rat stress model
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...

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...

OBJECTIVES To understand the mechanisms of postdefibrillation arrhythmias and failed defibrillation, we studied the cellular effects of high voltage shocks on different cardiomyocytes in the dog. BACKGROUND The causes of postdefibrillation arrhythmias and unsuccessful defibrillation are not clear. METHODS High voltage shocks with voltage differentials of 9.3 to 97.6 V/cm were delivered to i...
