DOI: 10.1002/joa3.13161
Abstract: Fractionated atrial potential (FAP) during sinus rhythm (SR) may be a new target for ablation of atrial fibrillation (AF). However, the effects of the direction of activation and premature atrial contraction (PAC) on FAP is… read more here.

DOI: 10.1038/s41598-021-91800-4
Abstract: Premature atrial complexes (PACs) have been suggested to increase the risk of adverse events. The distribution of PAC burden and its dose–response effects on all-cause mortality and cardiovascular death had not been elucidated clearly. We… read more here.

DOI: 10.1080/01443615.2017.1306693
Abstract: Abstract Foetal premature atrial contractions (PACs) are the most commonly encountered and also the most benign foetal arrhythmia. A retrospective cohort study was conducted with the objective to assess whether the presence of foetal breathing… read more here.

DOI: 10.1093/cvr/cvac054
Abstract: Abstract Premature atrial contractions are a common cardiac phenomenon. Although previously considered a benign electrocardiographic finding, they have now been associated with a higher risk of incident atrial fibrillation (AF) and other adverse outcomes such… read more here.

DOI: 10.1111/jce.14067
Abstract: Frequent premature ventricular contractions (PVCs) can cause cardiomyopathy (CM). Postextrasystolic potentiation (PESP) and irregularity have been in implicated as triggers of PVC‐CM. Because both phenomena can also be found in premature atrial contractions (PACs), it… read more here.
