Although several investigators have suggested the close relationship between the organ specificity involved with emotional stress and individual predisposition, the previous studies by the authors showed that the electrocardiographic abnormalities were observed with high incidence in the group suffering from peptic ulcer in the past compared with the group without gastrointestinal disorders. These results indicate that the organ specificity in psychosomatic diseases depend on the environmental factors rather than the individual predisposition. The purpose of the present studies is to investigate the modification of biorhythm under the environmental factors which include a number of daily activities and individual characteristics obtained from personal background in social life. Then, diurnal change of blood pressure, pulse rate and CV values were provided as the parameters of biorhythm. The different situations of individual social background by occupation, activities of daily life and family make-up exert the significant influence on biorhythm. On the other hand, we were unable to find any evidence of a relationship between the results in diverse psychological tests and chracteristic changes of biorhythm. There were also minimum changes in blood pressure, heart rate and CV values in the bedfast aged group. Furthermore, it is known that micturition and feeding, as a factor related to pressor responses in daily life, can elevate blood pressure. However, to what extent the patient with cardiovascular psychosomatic disease may be more susceptible to the development of hypertension is still unknown. Blood pressure was measured serially in each cardiac pulsation. Blood pressure elevated immediately after the start of micturition and sustained during the micturition. The afterfall of blood pressure was usually observed. These pressure responses induced by micturition were significant in patients with hypertension and coronary insufficiency, in which arrhythmia was frequently encountered, whereas those in control subjects were scarcely observed. Similarly, pressure responses followed by feeding resembled those of micturition for the most part. It was proved that these evidences were due to the increase of sympathetic outflow to controlling organs by experimental studies. The present findings suggest that the analysis of individual environmental factors and of pressure responses induced by the activities of daily life is a very important proposition. Furtheremore, it plays an important role in daily life and makes a valuable principle for the treatment of cardiovascular psychosomatic diseases.
