The QRSS is a stand-alone program that calculates the predicted performance of an HMA pavement from the volumetric and materials properties of the as-designed HMA and compares it with that of the as-built pavement calculated from quality control data from the contractor's lot or sublot.
The J waves, upright waves at the junctions of the QRSs with the ST segments, are large and in hypothermic patients are called Osborn waves.

Thus, there appears to be only a short window of time soon after junction-initiated QRSs when atrioventricular conduction can occur.
The last five QRSs are fusions, again looking progressively more like accelerated idioventricular complexes and less like sinus-initiated complexes.
P waves seemingly have disappeared, but close inspection of the lead II rhythm strip reveals an upright P wave to be buried in each of the latter six QRS complexes, as manifested by their having a slightly wider base than either of the first two QRSs and by a slight notch occurring at the end of each of the latter six R waves (best seen in the last and third from last QRSs).
The other QRSs do not have these upright deflections.
In lead V1 this is seen as a notch and upward spike from the sixth QRS onward, whereas this deflection is not present in any of the first five QRSs. Likewise, a negative deflection is seen in leads II and aVF from the sixth QRS onward, but is not seen in the first five QRSs.
