Common ECG findings and the risk of cardiac arrest

Methods: We cross-linked individuals who had an ECG recording between 2001 and 2011 in primary care with the Danish Cardiac Arrest Register and identified OHCAs of presumed cardiac cause. Multivariable cause-specific Cox regression was used to estimate the association between the ECG abnormalities and OHCA and calculate the absolute 10-year risk of OHCA for men and women with and without known cardiac disease for different age groupings…

Results: A total of 326,227 individuals were included in the study and of those 2,667 suffered an OHCA during a median follow-up of 4 years. The following ECG findings were strongly associated with OHCA: ST-depression without atrial fibrillation (AF), left bundle branch block, and non-specific intraventricular block.
