The reasons why some individuals respond to psychological stress with malignant arrhythmia are both unclear and provocative. There is a connection between emotional stress and cardiac vulnerability. Behavioral response to stress and subsequent neuroendocrine response to emotion will eventually occur in susceptible individuals, but sensitivity to emotion is variable. Some individuals prone to cardiovascular disorders probably have in their character an oversensitivity to emotional arousal, psychological conflict, or personal loss. Such arousal can
