Echocardiogram, also known as echocardiography, or heart ultrasound is a noninvasive, painless test that uses high-frequency sound waves to visualize the shape, size, and movement of the structures of the heart. It is useful to evaluate patients with chest pain, enlarged cardiac silhouettes on X-rays, electrocardiogram (ECG) changes unrelated to CAD, and abnormal heart sounds on auscultation. In this test, a transducer directs ultrahigh-frequency sound waves toward cardiac structure, which reflect these waves. The echoes are converted to images that are displayed on a monitor and recorded on a strip chart or videotape. Results are correlated with clinical history, physical examination, and findings from the additional test. The techniques most commonly used in echocardiography are M-mode (motion mode), for recording the motion and dimensions of intracardiac structures, and two-dimensional (cross-sectional), for recording lateral motion and providing the correct spatial relationship between structures. The responsibilities of a nurse during echocardiography includes explanation of the procedure to the patient, monitoring during tranesophageal and stress examinations, and establishing intravenous access for sonicated saline, microsphere contrast, and medication administration. TypesThe different types of echocardiogram are:
IndicationEchocardiogram is indicated for several reasons, which includes:
ProcedureThe following are the steps and processes on how an echocardiography or echocardiogram is performed:
Interfering factorsThese are factors that may affect the outcome of echocardiography:
Nursing ResponsibilitiesThe following are the nursing interventions and nursing care considerations for a patient undergoing a normal echocardiogram: Before the procedureThe following interventions are done prior and during the study:
During the procedureThe following are the nursing considerations during echocardiogram:
After the procedureThe nurse should be aware of these post-procedure nursing interventions after an echocardiogram, they are as follows:
Normal resultsNormal findings of echocardiogram will reveal the following:
Abnormal results:Abnormal echocardiogram findings will show the following:
