Why the study?
Prehospital 12-lead ECG transmission is recommended for suspected STEMI, but existing methods lack convenience or carry substantial implementation costs.
May warrant broader prehospital ECG transmission in acute care; extends observational data but leaves open need for RCTs.
Background: The Japanese Resuscitation Council’s 2020 Guidelines recommend transmitting a prehospital 12-lead electrocardiogram (PH-ECG) for adult patients suspected of having ST-elevation myocardial infarction (STEMI). Nationwide, the primary methods of ECG transmission are either prefecture-specific emergency transport systems or cloud-based services. However, prefectural systems often lack convenience, while cloud-based services are associated with substantial implementation costs.
