An increasing number of users are surrounded by multiple computing devices such as PDAs and cell phones. There is some evidence that the use of mobile devices in health care settings might improve decision-making and reduce the numbers of medical errors. However, mobile devices are not commonly used in telemedicine and health care, and there is a lack of suitable functions and software applications...
A computer model has been developed to study the electrical activity of a Purkinje fiber of 1.5 cm coupled to a regionally 1B ischemic ventricular fiber of 3 cm through a Purkinje-muscle resistance (Rpvj). The ventricular fiber was composed of a 1B ischemic zone, a border zone and a normal zone of 1 cm each. To simulate ischemia, we altered several electrophysiological parameters of the Luo-Rudy action...
A computer model has been developed in which reflection was observed. Reflection is a type of reentry in a one-dimensional structure of cardiac cells. The model consists of two segments of ventricular tissue partially coupled by a coupling resistance (R) and it was used to study conditions that provoke the development of EADs, and the generation of reflection and ectopic activity. In the present study,...
