This paper reports the development of a help-diagnosis system where the physician is required to analyze some ECG pulses that can not be accurately classified by the system. A confidence measure is estimated on the basis of massive experimental tests on data from MIT-BIH Arrhythmia Database, and was set on a threshold above which no classification errors were obtained. Cardiac arrhythmia detect...

This study examined nonuniform postganglionic cardiac sympathetic neural discharge as a possible mechanism involved in the production of coronary occlusion or ouabain-induced arrhythmias. After acute occlusion of the left anterior descending coronary artery in 12 cats, anesthetized with alpha-chloralose and pretreated with atropine, arrhythmia occurred within 3 min in eight animals; three of th...

Recurrent ventricular arrhythmia can be fatal and cause serious complications, particularly when it is caused immediately after an operation. Incorrect placement of a Swan-Ganz catheter can trigger life-threatening ventricular arrhythmia, but even intensive care specialists tend to miss this fact. Here, we report a case of recurrent ventricular arrhythmia causing a severe hemodynamic compromise...

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 ...

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...

BACKGROUND Life stresses and negative emotions, such as anxiety and depression, are associated with adverse cardiac events, including arrhythmia. Patients undergoing implantation of an automatic internal cardioverter defibrillator provide a unique opportunity to characterize these relationships since all tachyarrhythmia episodes are recorded by the device. OBJECTIVES The purpose of this study...
