<qa>  What is the iECG capable of capturing and amplifying signals from theA novel electrocardiographic recording method, the iECG is capable of capturing and amplifying signals from the cellular level that are much lower biologic signals than those processed by a traditional electrocardiogram ECG. These recordings focus on early detection of myocardial abnormalities by non-linear analysis of electrical activity and physiological phenomenon. This novel assessment might be capable of detecting subclinical myocardial dysfunction in a variety of heart diseases.
