WebThe PR interval on resting 12 lead ECGs in children varies mainly in relation to heart rate and is therefore usually shorter in younger children. In infants with heart rates in the range 100–150 beats/min one would expect the PR interval to be within the range 80–110 ms extending in occasional individuals to 150 ms. WebFragmented QRS complexes (fQRS) are common in patients with arrhythmogenic cardiomyopathy (ACM). A new method of fQRS quantification may aid early disease detection in pathogenic variant carriers and assessment of prognosis in patients with early stage ACM. Patients with definite ACM (n = 221, 66%), carriers of a pathogenic ACM …
