Electrocardiographic changes in the ST segment during anesthesia: Things to consider

Abstract

cal hypoor dyskinesis, with sparing of the basal segments. Apart from these conditions, there are causes of genetic ardiac morbidity and mortality in non-cardiac surgery will epend on associated factors and the type of surgery. The ncidence can be up to 30%, and the high prevalence of eart disease in the general population requires constant igilance. Despite careful assessment and the control of trigering factors such as tachycardia, increases in catecholamine nd cardiac contractility levels may lead to an imbalance in yocardial oxygen supply and consumption. Sudden electroardiographic (EKG) changes in the ST segment may reflect myocardium where flow and demand are up to the limit, he manifestation of acute coronary syndrome (infarction, ngina), or plaque rupture in a patient with atherosclerosis. owever, in a large proportion of cases, these changes are tranient and do not result in irreversible damage of the cardiac uscle or a low output state. Coronary heart disease must be he first thing to rule out, which means that any change in the T segment must prompt a clear diagnosis and appropriate anagement in the event coronary heart disease is confirmed. It is important not to ignore other conditions or diseases hat may surface during anesthesia. In general, changes are ound to occur during intubation, and during the course of urgery because of catecholamine elevations, hypotension or leeding.
