ABSTRACT
BACKGROUND:
Whether the electrocardiography (ECG) serial changes predict outcomes in cardiac arrest survivors undergoing therapeutic hypothermia remains unclear. METHODS ANDRESULTS:
This retrospective observational study enrolled 366 adult nontraumatic cardiac arrest survivors who underwent therapeutic hypothermia in a tertiary transfer center during 2006-2018. The ECG at return of spontaneous circulation (ROSC), during hypothermia and after rewarming were analyzed. 295 cardiac arrest survivors were included. Compared with the survivors, the non-survivors had longer QRS durations at the ROSC (118.33 ± 32.47 ms vs 106.88 ± 29.78 ms, p < 0.001) and after rewarming (99.26 ± 25.07 ms vs 93.03 ± 19.09 ms, p = 0.008). The enrolled patients were classified into 4 groups based on QRS duration at the ROSC and after rewarming, namely (1) narrow-narrow (narrow QRS at ROSC and narrow QRS after rewarming, n = 156), (2) narrow-wide (n = 29), (3) wide-narrow (n = 87), and (4) wide-wide (n = 23) group. The wide-wide group had the worst survival rates [odds ratio (OR) = 0.141, p = 0.001], followed by the narrow-wide group (OR 0.223, p = 0.003) and the wide-narrow group (OR 0.389, p = 0.003).CONCLUSIONS:
In cardiac arrest survivors given therapeutic hypothermia, QRS durations at the ROSC, after rewarming and their changes may predict survival to hospital discharge.Palabras clave
