Summary

Emergency medical technicians (EMTs) performing prehospital 12-lead electrocardiograms (PTLs) slightly increased scene times by about five minutes. Physicians found these PTLs indicated and moderately helpful, suggesting feasibility for basic life support skills.

Area of Science:

  • Emergency medicine
  • Cardiology
  • Prehospital care

Background:

  • Prehospital 12-lead electrocardiograms (PTLs) are crucial for reducing time to thrombolytic therapy in cardiac events.
  • Paramedics routinely perform PTLs, but their use by emergency medical technicians (EMTs) is less common.
  • The integration of PTLs into basic life support (BLS) protocols requires evaluation of EMT performance and impact.

Purpose of the Study:

  • To assess if EMTs performing PTLs prolong on-scene times.
  • To determine EMTs' ability to appropriately select patients requiring PTLs.
  • To evaluate the perceived value of prehospital PTLs by receiving physicians.

Main Methods:

  • A prospective pilot study was conducted across four BLS agencies.
  • EMTs performed standard care on even days and PTLs on odd days.

  • Scene times were compared between patients receiving a PTL (n=77) and those not (n=100).

    • Main Results:

    • Adding a PTL increased mean scene time by approximately 5 minutes (16.9 vs. 11.9 minutes).
    • Physicians agreed that 93.6% of PTLs were indicated.
    • Physicians rated the helpfulness of PTLs as moderately useful on a 5-point scale (3.56).

    Conclusions:

    • EMT acquisition of PTLs is feasible, despite a modest increase in scene times.
    • Physician feedback supports the clinical indication and utility of EMT-performed PTLs.
    • Further validation in diverse BLS agencies is recommended to confirm these findings.
