BackgroundPerformance of cardiopulmonary resuscitation (CPR) causes significant mental stress for rescuers, especially if performed by inexperienced individuals.Our aim was to study electrocardiogram (ECG) alterations in rescuers and its association with gender and CPR performance.MethodsWe included 126 medical iphone 14 price chicago students in this prospective, observational simulator study.Each student was equipped with a 3-lead continuous ECG device tracking the individual electrocardiographic output before, during and after CPR.

We analyzed variations in heart rate, heart-rate variability (HRV) and ST- and T-wave morphology.ResultsCompared to baseline, mean heart rate (bpm) significantly increased during resuscitation bostik universal primer pro and again decreased after resuscitation (from 87 to 97 to 80, pConclusionCPR causes significant ECG alterations in healthy medical students with ST-segment and T-wave abnormalities, with more pronounced effects in females.Clinical implications of these findings need to be further investigated.
