[Evaluation of left ventricular function by external methods. Comparative study of systolic intervals and apexcardiography]. 1976

C M Brandt, and M Rauscher, and P Arnold, and J L Fincker

In a number of conditions characterised by major disturbance of myocardial contractility (15 cases of thyrotoxicosis, 18 of hypokinetic cardiomyopathy and 9 of hypertrophic cardiomyopathy), the authors have compared the results of measuring the systolic intervals as derived from the quotient PPE/TE with an analysis of the upstroke of the apex electrocardiogram derived from measurement of the t-da/dt interval and from the quotient da/dt/A. The quotient PPE/TE is markedly lowered in the hypokinetic cardiomyopathies. On the other hand this quotient does not differentiate between normal subjects and patients with thyrotoxicosis or hypertrophic cardiomyopathy. By contrast the measurements derived from the electrocardiogram, and especially the quotient da/dt/A, differentiate very clearly between the various pathological conditions.

D004562	Electrocardiography	Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.	12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead

D006332	Cardiomegaly	Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
