Das Ekg-ABC: Eine Systematik zur Auswertung von Elektrokardiogrammen

After a brief general discussion of cardiac anatomy and physiology, the various abnormalities of the different components of the electrocardiogram are listed and their meaning is discussed. Drawings are presented instead of actual records. The following examples are quoted in order to illustrate the erroneous statements made by the author: Disturbances of impulse conduction like sinoauricular block, auriculoventricular block and bundle branch block are listed as disturbances of impulse formation. Nonphasic sinus arrhythmia is stated to indicate myocardial damage. An instance of sinoauricular block where one of four sinus impulses is not followed by an auricular response is called 4: 1 sinoauricular block. Passive nodal rhythm is interpreted as evidence of complete sinoauricular block. The common type of intraventricular block is called right bundle branch block and the uncommon type left bundle branch block, and later it is stated, "according to recent investigations the intraventricular block of the uncommon type
