Wireless continuous single‐lead ST‐segment monitoring to detect new‐onset myocardial injury at the general ward—An exploratory subanalysis
Authors' conclusion
In conclusion, wireless single-lead ECG monitoring with corrected ST thresholds detected patients developing myocardial injury with specificities >90% and sensitivities <20%
Study context
- Population
- Patients after major abdominal cancer surgery or with acute exacerbation of COPD at the general wardincluded for analysis
- Participants
- 528 patients
- Comparison
- ST-threshold ≥10 min vs ST-threshold ≥20 min
- Outcome
- Myocardial injury (hsTnT 20-64 ng/L with absolute change ≥5 ng/L, or hsTnT ≥ 65 ng/L); detection by ST-deviation thresholds
- Follow-up
- Up to 4 days
Methodological detailsexploratory subanalysis, Wireless single-lead electrocardiogram (ECG) patch for up to 4 days with daily troponin measurements
- Exploratory subanalysis
- Wireless single-lead ECG patch for up to 4 days with daily troponin measurements
