STAFF III Database

The STAFF III database was acquired during 1995–96 at Charleston Area Medical Center (WV, USA) where single prolonged balloon inflation had been introduced to achieve optimal results of percutaneous transluminal coronary angiography (PTCA) procedures, replacing the typical series of brief inflations. The lead investigator Dr. Stafford Warren designed the study protocol together with Dr. Galen Wagner at Duke University Medical Center (Durham, NC, USA); Dr. Michael Ringborn (Blekinge Hospital, Karlskrona, Sweden) was responsible for data acquisition. The database consists of ECG recordings from 104 patients, accounting for substantial inter-patient variability in reaction to prolonged balloon inflation as well as variability of heart rhythm and waveform morphology. Only patients receiving elective PTCA in one of the major coronary arteries were included. Patients suffering from ventricular tachycardia, undergoing an emergency procedure, or demonstrating signal loss during acquisition, were excluded.

STAFF III 数据库于1995至1996年间在位于美国西弗吉尼亚州的查尔斯顿地区医疗中心采集，该中心引入了单次持续球囊充气技术以实现经皮腔内冠状动脉血管成形术（PTCA）的最佳效果，取代了传统的多次短暂充气方式。该研究的主要调查员斯塔福德·沃伦博士与杜克大学医学中心（美国北卡罗来纳州达勒姆）的加伦·沃格纳博士共同制定了研究方案；迈克尔·林博恩博士（瑞典卡尔斯克鲁纳的布莱金厄医院）负责数据采集。该数据库包含104位患者的心电图记录，展现了患者在持续球囊充气反应、心率及波形形态方面的显著个体差异。仅包括在主要冠状动脉中接受选择性PTCA手术的患者。排除患有室性心动过速、进行紧急手术或在采集过程中出现信号丢失的患者。
