[An inverse reaction of the ST-T complex in the elctrocardiogram due to beta receptor inhibition].
In this article shall be referred to a special form of reaction of the ST-T-complexes in the propranolol test. Instead of a normalisation of this section of the ECG an inverse reaction develops. It consists in the fact that after application of propranolol the negativities of the T-waves increase and the lowerings of the ST-distances deepen. They appear most frequently after an acute heart attack, such as after a spontaneous angina pectoris, and they can be reproduced only during some days. It is supposed that the cooperation of acute ischaemic myocardial processes with negative sequelae of the blockade of beta-receptors are responsible for this inverse reaction.
