ECG system choice markedly influences detected ischemia rates; leaves open optimal monitoring standards for perioperative risk assessment in CABG.
Does the choice of electrocardiographic system affect the detected incidence of perioperative myocardial ischemia in patients undergoing CABG?
The reported incidence of perioperative myocardial ischemia is highly dependent on the frequency response and specific electrocardiographic system used for monitoring.
Slogoff et al. (1990) studied this question.
