[Electrocardiographic and hemodynamic changes during systemic hyperthermia (42 degrees C)].
During systemic hyperthermia (42 degrees C), depression of ST segments or T wave changes in the left precordial leads were noticed in 56% of patients, and 29% of cases showed right bundle branch block. Supraventricular tachycardia was found in 26% and temporary deviation of mean frontal vector to the left axis was observed in 15%. These changes disappeared following recovery to normal temperature. The ECG findings for any particular patient were similar even during a second period of hyperthermia. Pulse rate became elevated by 1.7 times, and cardiac output became up to 2.4 times higher at 42 degrees C.
