Since its invention in 1839, Electrocardiography (ECG) has become an integral part ofclinical practice across the globe. Till today, multiple research work is being carried outwhere ECG holds immense significance. However, with the advent of newer technologies,the need has arisen for digital data from ECGs for research purposes (at times even morethan the graphs themselves).Today's world lacks 2 important aspects from this need :● An international repository for ECGs. Though multiple libraries for ECGs exist, noneare universal, very few have research value because of analogue data (picture of thegraph).● A user-friendly software to convert the analogue entries into digital data for use intoday's technologies.The Electrocardiogram Storage and Digitizer (E-STAD) gives users across the world theoptions to1. Upload ECGs onto the repository in either analogue or digital formats. The repositoryshall contain ECGs from Standard 12-Lead ECG machines along with device-basedECGs (like portable handheld devices and digital stethoscopes)2. Interconversions between analogue and digital data of ECGs3. Stabilisation of existing ECG digital data (ensuring 0 : baseline alignment)4. Modification of ECG amplitudes to suit the userE-STAD, available as a website, an app, and also as a plug-in ensures seamless integrationinto existing research platforms. With user-friendly interface, researchers alike caneffortlessly navigate through the repository, accessing a vast array of ECG data from diversesources. Moreover, E-STAD employs state-of-the-art algorithms ensuring accuracy andfidelity of the converted data, making it invaluable for research.Additionally, E-STAD prioritises data security and privacy, implementing robust encryptionprotocols to safeguard sensitive patient information.In an era where data-driven insights are revolutionising healthcare, E-STAD stands as abeacon of accessibility and universality, empowering researchers to unlock new discoveriesand improve patient outcomes.
