[Features of ischemic myocardial contracture after asphyxia-induced cardiac arrest in rats].
OBJECTIVE
To investigate the features of ischemic myocardial contracture after asphyxial cardiac arrest in rats.


METHODS
Asphyxial cardiac arrest was induced in 8 Wistar rats, and the length and width of the heart were measured at the different time points after cardiac arrest.


RESULTS
Obvious ischemic myocardial contracture occurred after the cardiac arrest, reaching the maximal contracture at 4-6 min after the arrest.


CONCLUSIONS
Ischemic myocardial contracture induced by asphyxia may be an important factor affecting the outcome of cardiopulmonary resuscitation.
