Jogging in place. Evaluation of a simplified exercise test.
The purpose of this study was to evaluate jogging in place as an electrocardiographic exercise test. Jogging in place continuously recorded via an ordinary single-channel electrocardiograph was compared with the Bruce treadmill protocol with a three-channel monitor and recorder in 141 cases with a wide spectrum of chest complaints. Agreement for the presence or absence of electrocardiographic ischemia (ST-segment displacement greater than or equal to 1 mm at 80 ms from the J point, or U-wave inversion) for the two tests was observed in 91 percent of the cases (95 percent confidence intervals: 86 percent to 95.5 percent). One hundred of the previous cases with paired electrocardiographic exercise tests were compared with the presence of reversible defects on exercise myocardial thallium-201 scintigraphy. The electrocardiographic ischemia had a similar correct classification rate in both methods (83 percent with jogging in place and 85 percent with Bruce treadmill protocol; not significant) against the finding of scintigraphic ischemia. This was also true for 52 cases having selective coronary arteriography. The correct classification rate was 54 percent (28/52) with jogging in place and 48 percent (25/52) with Bruce treadmill protocol (not significant). Given the safety and the easy applicability, even in older persons, this simplified test can be recommended as a valid alternative to the established multistage exercise tests.
