apexcardiography a·pex·car·di·og·ra·phy (ā'peks-kar'dē-og'ră-fē), Noninvasive graphic recording of cardiac pulsations from the region of the apex, usually of the left ventricle, and resembling the ventricular pressure curve.apexcardiography A technique that graphically records movements of the chest wall caused by the beating heart, which is used to evaluate left ventricular function, myocardial infarction (MI), aneurysms, ischaemia and pericarditis. Apexcardiography provides ancillary information and is used with EKG, phonocardiography and carotid or jugular vein pulse tracings. Abnormal values Absent or abnormal waves occur in atrial fibrillation, mitral and aortic valve stenosis, hypertension, hypertrophic cardiomyopathy, ventricular aneurysm, ischaemia, MI, and coronary artery disease. Procedure A transducer is placed on the patient’s chest, converting the mechanical force of the moving chest wall into electrical energy, which is then converted into an apexcardiogram.apexcardiography Cardiology A technique that graphically records movements of the chest wall caused by the beating heart, which is used to evaluate left ventricular function, MI, aneurysms, ischemia, and pericarditis; it provides ancillary information and is used with EKG, phonocardiography, and carotid or jugular vein pulse tracings Abnormal values Absent or abnormal waves occur in AFib, mitral and aortic valve stenosis, HTN, hypertrophic cardiomyopathy, ventricular aneurysm, ischemia, MI, CADa·pex·car·di·og·ra·phy (ā'peks-kahr'dē-og'ră-fē) Noninvasive graphic recording of cardiac pulsations from the region of the apex, usually of the left ventricle, and resembling the ventricular pressure curve. |
