Early repolarization pattern: innocent finding or marker of risk?

Webb17 feb. 2013 · Recently early repolarization has also been used to describe late QRS notching or J wave slurring. When defined as such in the inferior leads (II, III en AVF) it has been found to be associated with an increased risk of cardiac death (1 mm of ST elevation carried an OR of 1.3 and 2 mm an OR of 3.0 )[ 9 ] Webb14 apr. 2024 · PR interval is short.
