Cardiovascular complications during the postoperative period may be either primary or secondary, and present with different manifestations depending upon the patient's underlying cardiovascular status. While some cardiovascular complications are relatively transient and benign, others, such as ventricular dysrhythmias, are potentially life threatening. Accordingly, the PACU must be equipped with basic cardiovascular monitors for all patients, and with more advanced monitoring facilities (including on-line ST-segment monitoring and invasive pressure monitoring) for those at higher risk. Immediate availability of resuscitation drugs is essential. ST-segment monitoring in selected patients at risk of coronary artery disease or in whom it is documented is well justified, as recent evidence suggests that myocardial ischemia occurring in the first 24 h postoperatively is an independent risk factor for the development of serious cardiovascular complications including fatal and non-fatal myocardial infarction, congestive cardiac failure, and dysrhythmias ( GoJdma.D...!995). A description of contributing etiological factors for postoperative hypo- and hypertension is presented in Tab.l.® 5..
