Treadmill exercise test and ambulatory measures in XXXX attacks.

@entity1 @entity4697 @entity63 @entity591 @entity5433
Treadmill exercise test performance and ambulatory heart rate and activity patterns of 40 @entity1 with @entity4697 attacks were compared with 20 age-matched controls (control group 1) and 20 nonexercising controls (control group 2). All @entity1 underwent a symptom-limited exercise stress test. @entity4697 @entity1 and control group 1 wore an ambulatory heart rate/activity monitor for up to 3 days. @entity4697 @entity1 had a significantly higher heart rate at 4 and 6 METS than either control group. The max METS were 11.2 +/- 2.3, 13.5 +/- 2.3 and 11.2 +/- 1.8 for the @entity4697 @entity1 and control groups 1 and 2, respectively. One @entity4697 @entity1 had @entity63 on the treadmill at 12 METS. @entity4697 @entity1 had a significantly higher standing heart rate than controls. Furthermore, 11 of 39 @entity4697 @entity1 had @entity591 on standing compared with 3 of 40 controls. @entity4697 @entity1 had higher wake and sleep heart rates than control group 1, but the differences were not significant. These results are consistent with @entity5433 in @entity4697 @entity1 but may also be due to differences in physical conditioning. The treadmill can be useful for reassuring @entity1 and for identifying the rare @entity1 with @entity63 on exercise.
