Diagnostic hotspots and new viewpoint on atrial fibrillation accompanied with second degree atrioventricular block |
|
|
Abstract It has always been controversial to diagnose atrial fibrillation accompanied with second degree atrioventricular block. This paper summarizes the current diagnostic hotspots from both positive and negative aspects, and proposes a new viewpoint from the angle of ambulatory electrocardiography and LorenzRR scatterplot. The characteristic performances of LorenzRR scatterplot contribute to qualitatively diagnosing atrial fibrillation accompanied with second degree atrioventricular block.
