運動中の血圧値を心拍数から推定しようとした。そのために,自転車エルゴメーターによる運動負荷中の血圧と心拍数を同時に測定し,両者の相関を求めた。結果の概要は以下のごとくであった。1) 最大血圧と心拍数はほぼ直線的な相関関係にあり,心拍数の増加とともに血圧値が高くなる。2) 最大血圧は心拍数100以下におけるよりも,100以上において,心拍数増加に対する血圧値の上昇が著しい。3) 概して,年令の高い者及び安静時最大血圧の高い者は心拍数の増加に対して血圧の上昇がより大となる。4) 運動中の血圧は心拍数の測定値から推定できるものと考える。5) 安静時血圧は,ある時点での血圧と心拍数を同時に測定し,血圧値を補正して求めるのが妥当であると考える。これによって真の高血圧と興奮による一過性の高血圧を区別することができる。6) 最小血圧と心拍数には明確な相関関係を認めなかった。

The blood pressure and the heart rate during exercise using a bicycle ergometer were measured simultaneously. Seven healthy volunteers, whose ages ranged from 9 to 46, served as the subjects. The results on correlation between increase in blood pressure and increase in heart rate are as follows: 1) There is a highly significant correlation between systolic blood pressure and heart rate. The blood pressure increases concomitantly with an increase of heart rate. 2) The systolic blood pressure tendes to rise more rapidly when the heart sate is over 100 beats/min. than under 100. 3) It is noted that elder and/or hypertensive men show more increase in systolic blood pressure than in heart rate. 4) The systolic blood pressure during exercise is estimated by the graphic procedure of the regression line. 5) It is recommended that the systolic blood pressure at rest is corrected by the heart rate measured concurrently with the blood pressure. By this procedure, the true hypertension is distinguished from a transient high blood pressure caused by excitement. 6) No relationship is found between diastolic blood pressure and heart rate.
