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（STAFF III database）于1995至1996年在美国西弗吉尼亚州查尔斯顿地区医疗中心采集完成。彼时该中心已引入单次长时间球囊充盈技术，以优化经皮冠状动脉腔内成形术（percutaneous transluminal coronary angioplasty，PTCA）的手术效果，替代了此前常规的多次短时球囊充盈方案。

本研究的首席研究员斯塔福德·沃伦（Stafford Warren）博士与美国北卡罗来纳州达勒姆市杜克大学医学中心的盖伦·瓦格纳（Galen Wagner）博士共同设计了研究方案；瑞典卡尔斯克鲁纳市布莱金厄医院的迈克尔·林伯恩（Michael Ringborn）博士负责数据采集工作。

该数据库共收录104例患者的心电图（electrocardiogram，ECG）记录，涵盖了患者对长时间球囊充盈的反应个体差异、心律及波形形态的异质性。本研究仅纳入接受择期经皮冠状动脉腔内成形术的主要冠状动脉病变患者，排除合并室性心动过速、接受急诊手术或采集过程中出现信号丢失的病例。
