The Unipolar Precordial and Extremity Electrocardiogram in Normal Infants and Children By MARIANO

Electrocardiogram in asthmatic children.

THE electrocardiogram of presumably normal infants and children has been the subject of extensive investigation.''2 On the other hand, an extensive review of the literature failed to reveal reports of the electrocardiograms of infants and children suffering from pulmonary disease.'3' 14 Ziegler12 in 1951 recorded the electrocardiograms of normal inifants and children ranging in age from birth t...

The unipolar precordial and extremity electrocardiogram in normal infants and children.

Information regarding the normal unipolar electrocardiogram in the young ages is very limited. This study furnishes data obtained from 521 normal infants and children from birth to 13 years, using the V chest leads and the aV limb leads. Four age groups were noted in the evolution of the newborn pattern into the adult pattern as mainly reflected by the configuration of the QRS complex in V1. De...

Characteristics of the unipolar precordial electrocardiogram in normal infants.

Relationship between the electrocardiogram and the position of the heart as determined by biplane angiocardiography.

O VER 50 years ago, Waller pointed out the obvious correlation between anatomic and electrical phenomena, the mirror image electrocardiogram in situs inversus.' Shortly thereafter, Einthoven described other correlations between the position of the heart and the mean electrical axis in normal human subjects.2 These correlations were extended to hypertrophied hearts by Groedel and Monckeberg in 1...
