May facilitate ECG comparison in acute chest pain triage without J-point reliance; leaves open need for prospective validation.
Does J-point independent subtraction electrocardiography accurately detect ischemia compared to J-point synchronized methods in patients undergoing elective PCI?
A novel J-point independent subtraction electrocardiography method using onset-QRS synchronization can accurately detect cardiac ischemia, removing the need for expert J-point identification.
Haar et al. (2016) studied this question.
