Non Invasive Extra-corporeal ECG Signal Analysis Algorithm( NID Algorithm) for Myocardial Ischemia

The NIA algorithm is similar to the traditional 12-lead ECG equipment. By analyzing patient data, NIA algorithm provides more detailed results compared to traditional 12-lead ECG. Patients with suspected coronary artery disease are conventionally diagnosed and treated by cardiac catheterization. However, cardiac catheterization is invasive procedure. Unless clinical diagnosis is evident before cardiac catheterization, a treadmill exercise test, a nuclear medicine myocardial perfusion test, or a multi-direction coronary CT angiogram is usually performed to increase the accuracy of diagnosis. But these examinations are not accessible to all patients, and are time-consuming and costly.
