Introduction and objective

The door-to-electrocardiogram (ECG) time is recommended to be 10 minutes or less in patients with chest pain presenting to the emergency department (ED). The aim of this study was to identify factors associated with delays in the door-to-ECG time in patients admitted to the ED with acute myocardial infarction (AMI).

Patients and methods

A total of 186 patients (70% male, mean age: 65.0 ± 14.0 years) hospitalized for AMI were evaluated. The door-to-ECG time was prospectively measured from the time of patient arrival in the ED to the time of initial ECG acquisition (minutes). Statistical analysis was performed using ANOVA and multiple comparison tests (Bonferroni, Scheffé, Tukey, Duncan). P < 0.05 was considered statistically significant.

Results

The mean door-to-ECG time was 9.0 ± 12.3 minutes (1–60 min). See Table 1.

Conclusion

Our data show that among the analyzed factors only the absence of chest pain on admission was significantly associated with a prolonged door-to-ECG time. This finding suggests that early identification of AMI patients with atypical presentation should facilitate appropriate and timely management.
