Raw ECG Recordings from TDT System During Cardiopulmonary Resuscitation (CPR) in Rodents

This dataset contains raw electrocardiogram (ECG) recordings acquired from six rodents using a Tucker-Davis Technologies (TDT) data acquisition system. Each animal underwent three recording sessions, capturing ECG signals from both chest and ear electrodes. The recordings span four physiological phases: baseline (normal conditions), asphyxia (simulated cardiac arrest via respiratory arrest), CPR (manual cardiopulmonary resuscitation), and ROSC (return of spontaneous circulation). Data are stored in native TDT format (.tev, .tsq, .tbk) and organized by subject and session. These recordings support the development and benchmarking of adaptive filtering algorithms for biomedical signal enhancement during CPR.
