Objective The aim of this study was to determine the incidence of serious ventricular arrhythmias in a cohort of patients admitted to coronary care units for investigation and treatment of possible acute coronary syndrome.
Design Secondary analysis of prospective cohort study.
Setting Community teaching hospital.
Patients Adults (>18 years) admitted to coronary care unit with chest pain and non-ischaemic ECG.
Main outcome measures Rate of serious ventricular arrhythmia during hospital stay.
Results 397 patients were studied; median age 64 years, 65% male; median Thrombolysis in Myocardial Infarction score 3; troponin elevation 43%, final diagnosis myocardial infarction 32%. No patient in the study suffered a serious ventricular arrhythmia (0%, 95% CI 0 to 1.0%).
Conclusion Patients admitted to coronary care units for investigation and treatment of possible acute coronary syndrome with a non-ischaemic ECG have a very low rate of serious ventricular arrhythmia.
- chest pain
- ventricular arrhythmia
- acute coronary syndrome
