Heart attacks mostly occur in people who suffer from heart or heart-relate diseases if these diseases, are not detected early enough and treated problem will be occurred. There is a need for a reliable means of detecting these diseases to save the patients from these attacks which are increasing in proportion all over the world. Electrocardiography (ECG), which measures the electrical activity of the heart, generates a signal referred to as ECG signal or simply ECG and the shape of this signal tells much about the condition of the heart of a patient. Naturally the ECG signal gets distorted by different artifacts which must be removed otherwise it will convey an incorrect information regarding the patient's heart condition. One of the ways to eliminate ECG Artifacts is using Adjustable FIR Digital filters. The authors apply a specific filter which will allow only the desired signal to pass,. Thus the noise will be removed efficiently. In this proposed work the authors calculate the signal to noise ratio of ECG signal by different factors of Adjustable filters
