The electrocardiogram during emotional and physical stress.
The electrocardiographic response pattern during exercise at low and high heart rate was compared with the response pattern during emotional stress. Qualitative differences between exercise and emotional stress were obtained, i.e. during exercise the ST segment was more depressed, T-wave amplitudes were larger and QT and PQ were significantly shorter than during emotional stress. The results do not support the suggestion that emotional stress evokes an exercise-like cardiovascular response pattern, which may lead to a metabolically maladaptive situation. The results are in accordance with the hypothesis that the ECG changes during emotional stress are similar to the ECG changes during right stellate stimulation, while the ECG changes during exercise are similar to the ECG changes obtained during left stellate stimulation.
