SpletST segment depression and T-wave changes may be seen in patients with unstable angina Depressed but upsloping ST segment generally rules out ischemia as a cause. Also, it can be a normal variant or artifacts, such as: Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode [3] SpletPathological R-waves also indicate previous myocardial infarction Current European (ESC) guidelines suggest that R-waves may also be used to diagnose previous myocardial infarction. Criteria for pathological R-waves: R-wave ≥0,04 s in V1-V2 and R/S ratio ≥1 with concordant positive T-wave in absence of conduction defect.

Dominant R-wave in V1/V2 implies that the R-wave is larger than the S-wave, and this may be pathological. If the R-wave is larger than the S-wave, the R-wave should be <5 mm, otherwise the R-wave is abnormally large.
