[Cardiac involvement in urticaria]

Cardiac involvement in patients with urticaria is rare, but repeatedly assured in publications. Subjective complaints concern chest pain, which extends to the left shoulder and the left arm. Transient electrocardiographic changes can be observed more frequently and they often persist longer than the ches pain. In these patients the most frequent electrocardiographic changes consist in flattening or inversion of the T-wave and depression of the ST-distance. Such a patient is described who additionally showed monotopic extrasystoles.
