Key result

Prehospital ECG teletransmission accelerates STEMI diagnosis and shortens reperfusion times via direct PCI referral.

Why the study?

ACS remains a leading cause of cardiovascular mortality worldwide, where rapid diagnosis and timely reperfusion are crucial, warranting a summary of evidence on prehospital 12-lead ECG teletransmission.

Does prehospital 12-lead ECG teletransmission improve diagnostic accuracy and reduce treatment delays in patients with acute coronary syndromes?

Implication

May shorten STEMI delays in networks; extends observational data but leaves open prospective validation and scalability.

Key Points

To summarize evidence on prehospital 12-lead ECG teletransmission for acute coronary syndrome diagnosis and assess its impact on systems of care and clinical outcomes.
Narrative literature review of PubMed from 1998 to 15 May 2026 covering ECG teletransmission, STEMI networks, treatment delays, and logistics.
Included professional clinical guidelines from the European Society of Cardiology and the 2025 ACC/AHA/ACEP/NAEMSP/SCAI consensus.
Meta-analysis data revealed digital transmission reduced first medical contact-to-device time by 24.7 minutes and door-to-device time by 33.3 minutes, lowering mortality (OR 0.53, 95% CI 0.40–0.69).
Prehospital ECG interpretation achieved pooled sensitivity of 80% (95% CI 69–88%) and specificity of 97% (95% CI 94–98%), while remote specialist interpretation had 72% sensitivity and 98% specificity.
False-positive catheterization laboratory activations ranged from 11% to 16%, primarily caused by bundle branch blocks, early repolarization, myocarditis, and artifacts.

Structured PICO

Does prehospital 12-lead ECG teletransmission improve diagnostic accuracy and reduce treatment delays in patients with acute coronary syndromes?

Population

A narrative review of literature evaluating the clinical and organizational impact of prehospital 12-lead ECG teletransmission in patients with acute coronary syndromes.

Intervention

Prehospital 12-lead ECG teletransmission (real-time or store-and-forward) integrated into regional STEMI systems of care.

Comparator

Standard prehospital care without ECG teletransmission or conventional ECG interpretation.

Outcome

Impact on systems of care, treatment delays (first medical contact-to-device and door-to-device times), and diagnostic accuracy.

Prehospital 12-lead ECG teletransmission is an essential component of contemporary STEMI care systems that significantly reduces reperfusion delays and improves care organization.

Limitations

Interpretation variability
False-positive catheterization laboratory activations
Infrastructure-related barriers
Absence of direct patient contact
interpretation variability
false-positive catheterization laboratory activations
infrastructure-related barriers

Cite This Study

Tomczak et al. (2026) conducted a review in Acute Coronary Syndrome. Prehospital 12-lead ECG teletransmission vs. Standard care without teletransmission was evaluated. Prehospital ECG teletransmission enables earlier STEMI diagnosis, direct referral to PCI-capable centers, and reductions in first medical contact-to-device and door-to-device times.
