Origins of ECG and Evolution of Automated DSP Techniques: A Review

Over the years, researchers have studied evolution of Electrocardiogram (ECG) and complex classification cardiovascular diseases. This review focuses on ECG covers most recent signal processing schemes with milestones over last 150 years systematically. Development phases ECG, leads, portable monitors, Signal Processing Complex Transformations are discussed. paper summarizes development features detection for cardiac anomalies history beginning from String Galvanometer. It also discusses automated detections 1960 to techniques. Additionally, this provides recommendations future research directions.
