The first record of hypertension in children was that of von Basch,1 who worked in Morton's clinic in Vienna, Austria, about 1894. In 1903 Cook2 took readings of blood pressure of sick children at the Johns Hopkins Hospital.
Of the numerous methods of determining blood pressure, the most practical and accurate clinically is still Korotkopf's3 auscultatory method, which, by the use of a 9 cm. cuff, is a modification of the Riva-Rocci method. Certain authorities, such as von Recklinghausen,4 claimed errors were frequently caused by the use of a too narrow cuff. That author insisted that one less than 10 cm. wide should never be used. Yet readings average only 5 mm. lower with the wider than with the narrower cuff, and the narrower cuff is more easily adjusted to the arm of a child.
The literature is replete with cases of great divergence in results.
