Electrocardiographic changes during cholangiopancreatography: Subjects

Thirty patients scheduled to undergo ERCP were recruited to the study and were monitored elecrocardiographically with Holter tape recorders. Written informed consent was obtained for data correction and storage on magnetic media. The patients included 18 women and 12 men of mean age 73 years (SD 2, range 71 to 79 years). Their mean weight was 66.5 kg (SD 18.3, range 44 to 100). All current medications were continued to the time of the procedure. No oxygen was administered in the observation period. Premedication was not given until few minutes before ERCP. Diazepam and Buscopan (Boehringer Ingelheim, Canada) were given for sedation and duodenal relaxation.

No opioids were given in the study period. Data were not available to the investigator, the endoscopist or the radiologist during the procedure. The clinical characteristics of the patients are outlined in Table 1. Best quality drugs are something you have been looking for all this time?
