A simple independent prognostic electrocardiography parameter in first acute anterior myocardial infarction; Precordial total Q wave/precordial total R wave.
Journal of Electrocardiology(2018)
摘要
•Q/R in admission ECG in patients with first acute anterior MI treated with PPCI provide an independent prognostic marker of in-hospital outcomes.•Correlation was demonstrated between LVEF and precordial total R wave, total Q wave, ST segment elevation and Q/R.•The prognostic power of Q/R in anterior MI arises out of Q and R waves’ amplitude response to transmural ischemia.
