ECG SIGNAL ANALYSIS: 

          Modern medical science using latest bio-medical instruments has made dramatic progress in prolonging life by overcoming diseases. The use of computers for processing electrocardiographic data and its ability to record large amounts of relatively artifact-free data, especially after the onset of signal in the form of electrocardiogram has been an encouraging and a valuable step forward. However, new problems have been sprout with the developing technology. The time associated with accuracy has been set target to the   biomedical engineers across the world.

                  Clinical  observations  of  ECG  signal on complex  graphs  with 12  leads information  would  be a laborious job when time is one’s primary concern. Having to decide various causes of disease and its origin, a cardiologist has to buy extra time to attend the subject. This report would be an innovative tool in exploring various kinds of cardiac diseases and its cause. This tool accounts for different morphologies, based on a sequential criterion, logically relates the symptoms or features of ECG signal and evolves a specific disorder. The logic relates features of amplitude, time period, axis and morphologies of P wave, QRS wave and etc...

                    This sequential inputs at very possible nodes and its decision making, drives the algorithm and feedback loop in updating the enormous information into this design.
