Neuro-fuzzy Classifier for Cardiac Arrythmias Recognition
The premature ventricular contraction (PVC) and the premature atrial contraction (PAC) are cardiac arrhythmias which are widely encountered in the cardiologic field. They can be detected using the electrocardiogram signal parameters. We use in this work a Neuro-fuzzy approach to identify these abnormal beats. To achieve this objective we have developed a Neuro-Fuzzy Classifier (NFCL), its perfo...
متن کاملThe Termination of Cardiac Arrythmias by Direct Current Shock.
THE use of DC, shock in the treatment of cardiac arrhythmias has been pioneered by Lown and his associates 1(1962). We are reporting our first 100 patients treated by this method. For those unfamiliar with this technique a short historical and technical introduction is appended. Introduction In 1899 Prevost and Batelli showed that the passage of a small current through the heart muscle (shock) ...
متن کاملcardiac arrythmias in acute and chronic renal failure
cardiac arrythmias are frequent complications in acute and chronic renal failure and they may well account for sudden unexplained death in these patients. based upon our recent study, we strongly believe that among other causative factors, focal degeneration of myocardium is the commonest and the most potentially dangerous cause of cardiac arrythmias. we suggest in emergency instances, ouabain ...
متن کاملEffect of L-carnitine on cardiac hemodynamics.
The effect of L-carnitine on cardiac hemodynamics was evaluated in normal closed chest dogs. Extracorporeal circulation was produced to measure coronary blood flow in closed chest dogs. Coronary venous blood was introduced to the extracorporeal circuit through a polyethylene catheter wedged into the coronary sinus under fluoroscopic control and was returned to the animal through the jugular vei...
متن کاملEffect of ventricular shock strength on cardiac hemodynamics.
INTRODUCTION The effect of implantable defibrillator shocks on cardiac hemodynamics is poorly understood. The purpose of this study was to test the hypothesis that ventricular defibrillator shocks adversely effect cardiac hemodynamics. METHODS AND RESULTS The cardiac index was determined by calculating the mitral valve inflow with transesophogeal Doppler during nonthoracotomy defibrillator im...
