Electrocardiographic changes associated with allergic urticaria.

One of us (Rogen, 1957) has reported a patient in whom extensive cardiographic abnormalities were associated with massive urticaria, the abnormalities being of short duration and clearing with rapid recovery from the urticaria. Her condition is summarized shortly as Case 2. The first patient reported here as Case 1 had associated mild urticaria only, but the electrocardiogram showed features similar to those previously reported by others. We have been given notes about another patient (Case 3), similar except that the cardiographic changes lasted for longer.
