Abstract

Cardiokymography (CKG) is a noninvasive method for the registration of left ventricular wall motion. Ischemic left ventricular wall-motion abnormalities (WMAs) can be detected by typical changes of CKG curves,The purpose of our study was to evaluate the sensitivity and specificity of a recently developed signal-averaged CKG system for the detection of stress-induced ischemic WMA, We investigated 74 patients who underwent dobutamine stress echocardiography (DSE) for suspected or proven coronary artery disease), Precordial CKG curves were recorded at rest and at peak stress with dobutamine, A positive CKG test (indicating ischemic WMA) was defined by typical changes of the CKG curves at peakstress compared to baseline recordings, The CKG test was positive in 28 of 38 patients with dobutamine-induced echocardiographic WMA (sensitivity 74%) and without pathologic changes of the baseline CKG curves in 29 of 32 patients with a normal DSE test (specificity 91%), The presence or absence of echocardiographic WMA at baseline did not influence the sensitivity or specificity of the CKG test, There was no significant difference in detecting patients with anterior or posterior WMA by CKG, The results of our study demonstrate that signal-averaged CKG can be used to detect patients with ischemic left ventricular dysfunction. The sensitivity of CKG test is not influenced by the presence of baseline WMA at rest and does not depend on the location of left ventricular ischemia.
