Food intake patterns of infants with high serum cholesterol level at six months.

In our longitudinal study on the influence of nutrition upon health during infancy we found in a cohort of 556 infants in good health, 6.4% of infants at six months with a total serum cholesterol level above 200 mg/100 ml. Because of the known importance of hypercholesterolemia for health we studied the role of the food intake patterns during the first six months in relation to the serum cholesterol. We analysed the 24 hours dietary recalls, the dietary habits and a set of biochemical determinations used for evaluation of nutritional status: 35 infants, 21 girls and 14 boys, were compared with a control group matched for sex and birth date. There were no differences in mean body weight and socio-demographic characteristics. Daily energy and protein intake was higher in the study group. Analysing milk consumption we found that the daily intake was always higher in the high cholesterol group. The solid foods were introduced earlier in the study group, i.e. for 46% of infants in the second week of life. The serum levels of vitamins A, C, and E, and of triglyceride were higher in the high cholesterol groups. At twelve months 33% of infants with the cholesterol level above 200 mg/100 ml we included in the studied group remain still with a high level. This tendency underlines the need of further research.

Atrial tachycardia without P waves masquerading as an A-V junctional tachycardia.

Two patients who presented by scalar ECG with an A-V junctional tachycardia were demonstrated during an electrophysiologic evaluation to have an atrial tachycardia without P waves in the surface ECG. Case 1 had an atrial tachycardia that conducted through the A-V node with a Wenckebach block. Atrial activity was recorded only from the proximal portion of the coronary sinus and from right atrial areas near the tricuspid valve. Case 2 had an atrial tachycardia that abruptly began and terminated following carotid sinus massage. Atrial activity was recorded only in the coronary sinusos, and pacing at that site resulted in atrial capture, with Wenckebach conduction to the ventricles. These observations demonstrate that an atrial tachycardia without P waves can simulate A-V junctional tachycardia with or without Weckebach block. Such findings may have a bearing on some important electrophysiologic concepts such as the origin of A-V junctional rhythms and the need for atrial participation in A-V nodal re-entry.

Should ECG criteria be modified for geriatric patients?

When an elderly patient has an abnormal electrocardiogram but no other objective evidence of heart disease, the physician may question whether the ECG is really a reliable index of heart disease in old people or whether aging has some influence on which findings are normal and which are abnormal. The study reported here plus data gathered from an extensive review of the literature indicate the ECG criteria do not have to be changed for geriatric patients. Regardless of age, the prognosis of a specific abnormality remains that of the underlying disease. With age, both heart disease and abnormal electrocardiograms increase in incidence--in a parallel fashion. Specific abnormalities that increase in frequency are first-degree atrioventricular block, bundle-branch block, ST-T wave changes, premature systoles, left anterior hemiblock, left ventricular hypertrophy, and atrial fibrillation. Those that correlate strongly with heart disease are atrial fibrillation, left bundle-branch block, and nonspecific intraventicular condution defect.
