title: [Electrocardiogramme in anaphylactic shock in humans (author's transl)].
abstract: Twenty clinical cases described in the literature were gathered, in which electrocardiographic tracings had been recorded. Electrocardiographic changes were found in all cases, such as sinus tachycardia (12 times), impaired electrical conduction (5 times), ventricular overexcitability (7 times), high P-wave (6 times), changes of the ST (10 times), and of the T-wave (18 times). The reason for these changes might be of a complex nature. Based on experimental investiagations mentioned in the discussion, it may be assumed that beside a direct effect on the myocardial cells, the following mechanisms could have influenced the electrical heart potentials: 1. a constriction of the coronary vessels, 2. a pulmonary vascular constriction, 3. an aggregation of thrombocytes, 4. a peripheral vascular dilatation, 5. a bronchiolar constriction.
