Which precordial ECG leads are most sensitive for detecting perioperative myocardial ischemia and infarction in patients undergoing vascular surgery?
Lead V4 is more sensitive than the conventionally used V5 for detecting perioperative ischemia, and using at least two precordial leads is recommended to achieve >95% sensitivity.
Landesberg et al. (2002) studied this question.
