The normal electrocardiogram.
O NE of the most difficult tasks which confronts the w orker in the life sciences is to define a normal. The difficulty is compounded when the measurement to be made is affected by many variables which differ in importance from time to time. These remarks apply to the electrocardiographer, and to the normal electrocardiogram. Some variables which affect the electrocardiogram are quite well know...
متن کاملThe genesis of the normal electrocardiogram.
The argument of this paper is based on the great work of Lewis, and all references to "Lewis, 1925" are to the third edition of The Mechanism and Graphic Registration of the Heart Beat. His demonstration (confirming Engelmann, 1875) that the contraction wave passes through cardiac muscle from the point of stimulation in all directions with equal velocity (p. 84); his considered view of the dire...

متن کاملNew normal limits for the paediatric electrocardiogram.
AIMS Previous studies that determined the normal limits for the paediatric ECG had their imperfections: ECGs were recorded at a relatively low sampling rate, ECG measurements were conducted manually, or normal limits were presented for only a limited set of parameters. The aim of this study was to establish an up-to-date and complete set of clinically relevant normal limits for the paediatric E...
