Patterns depicted in the LPs were described.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Arrhythmia-free Holter recordings yielded LPs with a Y-shaped pattern and variable silent zones. Recordings with single premature complexes yielded LPs with double side and triple side lobes. Complex ectopy was denoted by dots clustered in the lower left corner of the LPs. The LPs of recordings with atrial fibrillation had fan patterns consistent with a nonlinear relationship between atrial electrical impulses and atrioventricular nodal conduction. The recordings with atrioventricular block yielded LPs with island patterns consistent with variable atrioventricular nodal conduction.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s005\">\n<jats:title>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Distinct LP patterns were identified for common cardiac rhythms of dogs, supportive of nonrandom mechanisms as the cause of most rhythms. Visual interpretation of an LP generated from a Holter recording may aid in determining the arrhythmia type and understanding the arrhythmia's mechanism in dogs and other species.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.81.9.720","type":"journal-article","created":{"date-parts":[[2020,8,25]],"date-time":"2020-08-25T12:44:21Z","timestamp":1598359461000},"page":"720-731","source":"Crossref","is-referenced-by-count":5,"title":["Visual
