Predictive value of a fragmented QRS complex in diagnosing patients with myocardial ischemia
Sign Up to like & getrecommendations! Published in 2019 at "Clinical Cardiology"
DOI: 10.1002/clc.23148
Abstract: A fragmented QRS complex (fQRS) is caused by conduction abnormalities of the ventricle secondary to myocardial ischemia and/or scar in patients with myocardial infarction. However, the implications of the fQRS in the development of coronary… read more here.

DOI: 10.1002/joa3.12582
Abstract: Determining factors for sufficient QRS amplitude and discernible P‐wave sensing in implantable loop recorder (ILR) are unknown. We aimed to investigate determining factors and ILR implantation angle that may improve QRS complex and P‐wave sensing… read more here.
