A similar dose comparator study, using another product, was reported in a neighboring poster by Ulrich Kleeberg, MD, from Haematologisch-Onkologische Praxis Altona, in Hamburg, Germany. This study compared epoetin beta at a dose of 30,000 IU once weekly with 10,000 IU given thrice weekly in 1458 patients. Most of these patients had solid tumors (371 had hematologic cancers) and were undergoing chemotherapy.

The dose of ATP needed to block the antegrade conduction of the AVN was obviously related to the antegrade and the antegrade ERP of the AVN. That is, the better the antegrade conduction and the shorter the antegrade ERP of the AVN, the larger the dose of ATP needed to block its antegrade conduction.

阻断房室结前向传导所需ATP与房室结前传功能、房室结前传有效不应期有明显相关性，房室结前传功能越好，房室结前传有效不应期越短，阻断房室结前传所需ATP剂量越大。
