heart rate variability test

(redirected from swing test)

heart rate variability test

A test that measures swings in heart rate over 24 hours via a Holter (portable EKG) monitor, identifying high-risk congestive heart failure patients. If heart rate variability is high, the prognosis is good; if low, therapy may be adjusted to reduce the risk of congestive heart failure.

We recently use a new physical examination technique, the swing test, to detect valgus deformity during knee flexion.
Every knee was evaluated using both the swing test and traditional radiographic analysis (regarded as the “gold standard”) by two surgeons independently.
During the swing test, we let the patient sit on a firm and rigid examination board, with the board edge right under their knees.
The sensitivity, specificity, and accuracy of the swing test were 82.6%, 100%, and 85.2% of those of radiographic analysis, respectively.
The swing test is a simple physical examination technique to detect whether valgus deformity exists when the knee flexes.
The swing test is useful for categorizing valgus knees according to classification systems based on origins of deformity and thus for individualizing surgical treatment for the patients.[sup][3]
If the swing test is positive, the valgus deformity probably exists in the tibia or results from a bone defect of the posterolateral femoral condyle, which can be easily differentiated further by a malalignment test performed on the long-film radiograph.
If the swing test is negative, there will be no deformity or just a slight deformity (<5[degrees]) in the posterior aspect of the femoral condyle and the tibia.
The non-tape group would have their strength test without the KT and thereafter the swing test would be conducted.

Rats that had failed the swing test now moved from side to side.
