Question Answer
Systoleaction of the chambers of the heart becoming smaller and ejecting blood
Troponin I,is elevated within hours after myocardial injury.
S3normal finding in children and adults up to 35 or 40
Cardiac outputcan be affected by changes in either stroke volume or heart rate
Agingwidening of the aorta, thickening and rigidity of the cardiac valves, increased connective tissue in the SA and AV nodes and bundle branches, and an increased left ventricular ejection time (prolonged systole).
Pulmonary artery pressure monitoringleft ventricular function (cardiac output), diagnosing the etiology of shock, and evaluating the patient's response to medical interventions, such as fluid administration and vasoactive medications
Arterial vasoconstrictionincreases the systemic vascular resistance, which increases the afterload
transesophageal echocardiographymaintain bed rest with the head of the bed elevated to 45 degrees.
Cardiac catheterizationassess coronary artery patency to determine if revascularization procedures are necessary
PAPMleft ventricular function
transthoracic echocardiography test is noninvasive, and nothing will be inserted into the patient's body.
normal CVP is 2 to 6 mm Hgelevated CVP, Assessing the patient and informing the physician
pulmonary artery catheter :evaluate left
ventricular filling pressures (i.e., left ventricular preload)
