About

ECG Buddy Research

Read full description

ECG Buddy Research — for ECG AI research and education ECG Buddy (EB) Research is a tool for researching and teaching ECG AI. It is built for researchers, medical and nursing educators, and students to use ECG AI for research, education, and retrospective case review. Built on ARPI Inc.'s ECG analysis technology, it lets you explore development-stage, experimental biomarkers and next-generation versions, for research and educational purposes only. [What you can do] • Test ARPI Inc.'s analysis technology directly on a wide range of ECG images available in the public domain, such as those in textbooks, academic materials, and online. • Examine rhythm classification and digital biomarker outputs in a research and educational context, and review new biomarkers currently in development or research. • Use biomarker values and their interpretation for education and learning, including retrospective case review, conference presentations, and lecture and seminar material. [Important — please read] • EB Research is not a medical device and must not be used for any clinical decision-making, including patient diagnosis or treatment. • Many of the biomarkers and analysis tools this app provides are development- and research-stage items, and clinical accuracy is not guaranteed. • All outputs are provided for research and educational purposes only. When actual patient care is required, you must rely on a medical device cleared in your country and the judgment of a physician. • When using EB Research for research, determining whether IRB approval or exemption applies — and complying with the relevant procedures — is the responsibility of the user and their institution. Please ensure your use meets the ethical requirements appropriate to your study design. If an IRB approval letter was requested at sign-up, you must submit it within one month of account activation; if we do not approve it within that period, your account will be suspended. • For clinical ECG analysis, please contact us through the ARPI website (www.arpi.ai) or at contact@arpi.ai. [Usage policy] • One credit is used per analysis, and credits are issued automatically each month. • Start for free: analyze up to 3 per day and 30 per month at no cost. • Paid subscription ($19/month or $190/year): analyze up to 20 per day and 200 per month. For inquiries, please reach out through ARPI's official website ([www.arpi.ai](https://www.arpi.ai)).
