Relation between arrhythmic sensations, cardiac arrhythmias and psychological profile.

The relation between arrhythmic sensations and objective findings of ectopic arrhythmic activity was studied in 150 middle-aged men. Objective arrhythmias were studied by 24-hour Holter monitoring and subjective symptoms assessed by a questionnaire and a dairy protocol during the ECG recording. Psychological characteristics were described by means of a personality inventory, the Emotions Profile Index. No direct relationship was found between subjective symptoms and objective findings of cardiac arrhythmias. Those men, however, who complained of arrhythmic sensations but had no clinically important arrhythmias exhibited a few specific characteristics. They had no signs of organic heart disease and appeared less trustful and more aggressive than those with arrhythmias.
