BACKGROUND Recent reports critical of the performance of heart rate-adjusted indexes of ST depression during exercise electrocardiography have used J-point rather than ST segment measurements. However, no standard exists for the optimal time after the J-point at which to measure ST segment deviation.
Thus, bushing/roller wear should not be included in overall wear measurements. The standard procedure for measuring chain wear is to hold a ruler against the chain. With 1/2-inch spacing chain, 24 links should measure 12 inches new; if 24 links measures 12-1/8 inches, the chain has worn about 1%. The following shows a worn Regina CX-S and an unused Sachs chain.
