Because this technique can also avoid the electromagnetic interferences,it uniquely provides an ideal means for studying the mechanisms such as cardiac defibrillation.

Methods: 16 successful cases of cardiopulmonary resuscitation occurring in CCU wards in recent years were selected and discussed the resuscitative procedure.

Methods Orthogonal ECG(sagittal, x;transverse,y;and longitudinal,z) was recorded from 10 dogs during 10 seconds of electrically induced ventricular fibrillation followed by a defibrillation shocks with 50% probability of success.

Even though the software package is customised for use in electrical impedance tomography, it can be used for other biomedical research areas, such as impedance cardiography, cardiac defibrillation and impedance pneumography.

Objective: Cardiopulmonary resuscitative procedure of cardiac arrest patients occurring in CCU wards was discussed so as to increase survival rate of cardiac arrest. Methods: 16 successful cases of cardiopulmonary resuscitation occurring in CCU wards in recent years were selected and discussed the resuscitative procedure. Results: Cardiopulmonary resuscitation of 16 patients given the resuscitative procedure was successful. Conclusion: Successful rate of cardiopulmonary resuscitation occurring in CCU wards can...

Methods: 16 successful cases of cardiopulmonary resuscitation occurring in CCU wards in recent years were selected and discussed the resuscitative procedure. Results: Cardiopulmonary resuscitation of 16 patients given the resuscitative procedure was successful. Conclusion: Successful rate of cardiopulmonary resuscitation occurring in CCU wards can be increased when the cardiac arrest patients were given the resuscitative procedure.

Objective To investigate the correlation between the degree of phase coupling among orthogonal electrocardiogram(ECG) during ventricular fibrillation(VF) and the defibrillation shock outcome.Methods Orthogonal ECG(sagittal, x;transverse,y;and longitudinal,z) was recorded from 10 dogs during 10 seconds of electrically induced ventricular fibrillation followed by a defibrillation shocks with 50% probability of success.The transvenous two-leads defibrillation system was implanted in the dogs to deliver defibrillation...

Objective To investigate the correlation between the degree of phase coupling among orthogonal electrocardiogram(ECG) during ventricular fibrillation(VF) and the defibrillation shock outcome.Methods Orthogonal ECG(sagittal, x;transverse,y;and longitudinal,z) was recorded from 10 dogs during 10 seconds of electrically induced ventricular fibrillation followed by a defibrillation shocks with 50% probability of success.The transvenous two-leads defibrillation system was implanted in the dogs to deliver defibrillation shocks.The degree of phase coupling was estimated by using the bispectrum.Results Comparison of bispectral energy between 206 successful and 221 unsuccessful trials in terminating VF showed that the unsuccessful trials had greater bispectral energy than the successful trials(p<0.05).Conclusion The study indicated that the degree of phase coupling among orthogonal ECG was correlated with shock outcome.

The objective of this study is to evaluate the correlation between the absolute ventricular fibrillation voltage(AVFV) computed from electrocardiogram(ECG) and the outcome of defibrillation shocks.Orthogonal ECG(sagittal,x;transverse,y;and longitudinal,z) was recorded from 11 dogs during 10 seconds of electrically induced ventricular fibrillation followed by defibrillation shocks with 50% probability of success.The transvenous two-leads defibrillation system was used to deliver defibrillation shocks.The envelope...

The objective of this study is to evaluate the correlation between the absolute ventricular fibrillation voltage(AVFV) computed from electrocardiogram(ECG) and the outcome of defibrillation shocks.Orthogonal ECG(sagittal,x;transverse,y;and longitudinal,z) was recorded from 11 dogs during 10 seconds of electrically induced ventricular fibrillation followed by defibrillation shocks with 50% probability of success.The transvenous two-leads defibrillation system was used to deliver defibrillation shocks.The envelope voltage was estimated by using the Hilbert transform.The comparison of the envelope voltages between 236 successful trials and 249 unsuccessful trials did not show any consistent and statistically significant differences.In contrast with the previously reported correlation,the moving average of AVFV was not higher in the successful trials.In the Z direction,the successful trials had lower voltage than did the unsuccessful trials(P<0.05).These results suggest that the absolute voltage of ECG during ventricular fibrillation is not robustly correlated with the outcome of defibrillation shocks.
