Description of Service
DSE123 is a free, open-source, web-based clinical decision support tool designed to assist with dobutamine stress echocardiography (DSE) workflows. The Application provides structured data entry, automated hemodynamic calculations, protocol guidance, and PDF report generation for stress echocardiography studies.

The Application is not intended for use by patients, the general public, or individuals without appropriate medical training and clinical context.
Not a Medical Device
DSE123 is a clinical workflow and calculation aid. It is not a registered, cleared, or approved medical device under any jurisdiction. It has not been evaluated by the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), or any other regulatory body. It should not be used as the sole basis for any clinical decision.
