[Noninvasive locational diagnosis of concealed accessory pathways in the heart]. 1989

C Y Lu

Concealed accessory pathways in the heart can be located by noninvasively mapping the left and right atrial potentials. The quantitative diagnostic criteria for locating the septal pathway are (1) the retrograde depolarization time difference between the two atria (delta A) = 0ms, (2) (delta A) less than 30 ms, (3) the change rate of delta A(delta A%) greater than 50%, (4) delta A index less than 10 and (5) the ratio of ventriculoatrial conduction time in the left to that in the right heart less than 1.2. These criteria have a diagnostic sensitivity of 100%, specificity of 87.5% and accuracy of 94.4%.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D013611 Tachycardia, Atrioventricular Nodal Reentry Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.
