A high-strength galvanized steel sheet having excellent formability contains as a chemical component of steel on a mass percent basis: 0. Data is provided that is associated with a plurality of cardiac arrhythmic episodes for which a cardiac electrical therapy was delivered or withheld by the implantable medical device based on the plurality of arrhythmia discrimination algorithms. The measuring cell is tubular, the inlet and the outlet are arranged at opposite ends, and the inner chamber of the measuring cell has a cross-sectional shape that is monotonic over the length of the tube and which has an oval-shape at the start, which disappears toward the end. The first throughput value is greater than the second throughput value when the count of code violations is less than a threshold and the first throughput value is smaller than the second throughput value when the count of code violations is greater than the threshold.
