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 کاملCongenital Hypofibrinogenemia Detected during Preoperative Workup for Major Cardiac Surgery
Afibrinogenemia or hypofibrinogenemia is a quantitative defect in fibrinogen. It is a rare disease with estimated frequency of 1 in 1,000,000 population. Routine preoperative screening tests of coagulation disorders are insufficient to detect subtle disorders of fibrinogen. Herein, we report a child who was supposed to undergo open cardiac surgery for a large atrial septal defect. Preoperative ...

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 کاملMonitoring awareness during cardiac surgery.
I today’s anaesthesia, monitoring brain functions is of increasing concern to the anaesthesiologist. Over decades anaesthesiologists have been careful providers of safety for their patients. Attention was focused on haemodynamic stability, pulmonary function, metabolic balance and pain control. However, in the practical operation room settings, the brain seems to be merely a black box. But we h...
