Summary
Transtelephonic ECG (TTE) provides diagnostic accuracy comparable to conventional ECG. This technology effectively reduces cardiovascular disease (CVD) mortality and disability by enabling faster treatment initiation.
Area of Science:
- Cardiology
- Medical Technology
- Telemedicine
Background:
- Transtelephonic ECG (TTE) was introduced in Slovenia in 1996 and operational since 1997.
- The system serves health institutions and patients with cardiovascular (CV) diseases.
- Portable 12-channel ECG devices under 200 grams are utilized by patients.
Purpose of the Study:
- To evaluate the diagnostic accuracy of transtelephonic ECG.
- To assess the impact of TTE on patient outcomes and healthcare costs.
- To compare TTE diagnoses with conventional ECG findings.
Main Methods:
- Analysis of 852 calls over 20 months, with 450 diagnostic assessments.
- Review of common reasons for calls: chest pain, palpitations, dyspnea.
- Follow-up of patients referred to the ER for accuracy validation.
Main Results:
- Common diagnoses included AMI, angina pectoris, and paroxysmal tachycardias.
- Cardiologist advice was sufficient in 186 cases; 171 patients were referred to the ER.
- 82 patients received medication adjustments based on TTE evaluation.
Conclusions:
- TTE demonstrates diagnostic accuracy equivalent to conventional ECG.
- TTE use shortens time to treatment initiation for CV diseases.
- TTE is associated with reduced disability, mortality, and improved cost-benefit.
