Simplified biomedical system for artificial defibrillation

Abstract

Sudden deaths due to various forms of heart failures are very common at present, especially in Sri Lanka. Whatever the causes and types of ailments are, the final stage known as fibrillation causes the patient to die within minutes. Fibrillation is the complete disorder of the heart beat pattern as shown in the Electro-cardiogram (ECG). In order to overcome this condition, it is attempted to give a strong electrical pulse to the heart of the patient, this is done by the use of an equipment called the defibrillator. It is seen that only a few hospitals are equipped with this instrument in Sri Lanka, mainly due to its high cost. This paper presents a design of low cost defibrillator, which will work on a new concept with advanced features and hardware system satisfying the safety standards found in commercial equipment.
