Blood pressure and heart rate responses during 24-hour ambulatory monitoring and exercise in @entity1 with XXXX .

@entity1 @entity6 @entity16 @entity1897 @entity4148
The heart rate (HR) variation of 25 normotensive and asymptomatic @entity1 , mean age 58 +/- 7 years, with @entity6 (group I) was studied during deep respiration. Thirteen subjects (52%) had a variation of 10 beats/min or less, consistent with an @entity4148 ( @entity4148 ) (group IA); 12 had variation in HR of more than 10 beats/min and were considered to have no @entity16 (group IB). The 24-hour ambulatory HR and systolic blood pressure (BP) values of group I were compared with those of 13 healthy @entity1 , mean age 48 +/- 8 years (group II). The mean of 5 maximal HR measurements during the 24-hour period was higher for group IA (106 +/- 11 beats/min) than for group IB (100 +/- 13 beats/min) or for group II (92 +/- 9 beats/min) (p less than 0.01). The mean of 5 maximal BP measurements was greater for group I (149 +/- 28 mm Hg) than for group II (128 +/- 13 mm Hg) (p less than 0.01), but no difference was observed between groups IA and IB. Maximal treadmill exercise was performed with 22 of the @entity1 (11 with and 11 without @entity4148 ), and no difference in HR was observed between the 2 groups during all stages of exercise or at maximal exertion. The increase in systolic BP and duration of exercise in these 2 groups were also similar. Seventeen of 25 @entity6 @entity1 had @entity1897 ( @entity1897 ). Of 13 @entity1 with @entity4148 , 10 had @entity1897 ; of 12 without @entity4148 , 7 had @entity1897 and 5 did not.(ABSTRACT TRUNCATED AT 250 WORDS)
