Abstract: Systems and methods for obtaining, storing and analyzing electrocardiogram (ECG) data utilizing the cloud virtualized unlimited resources to aid in the process of detection of arrhythmia on ECG data. It also comprises various cloud-based interactive graphic editing tools, to augment medical practitioners' capabilities in the course of inspecting and editing any misinterpretations. This system captures the ECG data from ECG devices to databases utilizing cloud communication and stores in various storage modules such as ECG signal data, record annotation, and patient's information.
