A problem of identifying the phase response curve of the myocardial pacemaker was investigated using a simple dynamic system model of cardiac arrhythmia. A hybrid optimization method of a genetic algorithm and a local optimization technique was employed to obtain a solution of the model fitting. The method was applied to two categories of arrhythmias,(More)
A high-speed continuous-system simulator of the multi-microprocessor configuration will be presented. This system is composed of simple microprocessor units and carries out highly parallel operations on a small task level. The processor unit is controlled by the microprogram and only performs basic operations such as integration, addition, and(More)
1. INTRODUCTION. Training in the diagnosis of arrhythmias is an important part of the curriculum for medical students, postgraduates, and paramedical staff. Although several CAI for arrhythmia have been developed [1-3], we could not get CAI software for arrhythmia for the MS-Windows environment. In this report, we present a newly-developed computer-assisted(More)
Electrocardiograms by standard limb lead, augumented unipolar limb lead and AB (Apex-Base) lead were recorded from 24 unanesthetized adult cats from a SPF closed colony. The unanesthetized cats were held in the sternal position or in the right lateral recumbent position by means of a net. The mean electrical axes of P, QRS and T waves were calculated on the(More)
We have developed Windows-based software for ECG training as a tool in teaching physiology. A standard user interface allows the user to choose which arrhythmia to review. The arrhythmia is drawn in real time with sound beeps synchronized to R waves. The system also presents a brief summary or multiple choice question corresponding to the arrhythmia. A(More)
