Results After pneumomediastinum(PM),as compared with the baseline measurements,the venacaval pressure raised and the cardiac output decreased significantly.
Early recognition of pneumopericardium is important, because emergent pericardiocentesis may be required if there is clinical evidence of cardiac tamponade.
Objective:To evaluate the myocardial protective effects of HTK solution on immature and cyanosed myocardium in cardiac operation,through comparison with ST.
Objective To explore the effects of rhonchus on senile degenerated cardiac valvular disease (DCVD)and impairment features of valvular structure and function .
Taking cats as animal model , the postganglionic inferior cardiac sympathetic nerve activity is analyzed with DFA(detrended fluctuation analysis) to explored its fractality.
