Abstract：Objective To explore regularity of outbreak and distribution rule of paroxysmal atrial fibrillation（PAF）through the analysis of characteristics of PAF recorded in Holter monitoring. Methods Holter recordings were analyzed to record the time and number of the episodes of PAF，as well as other kind of arrhythmia. Results The incidence of paroxysmal atrial fibrillation was the highest（48.3% in patients with coronary heart disease）. The incidence was the highest in old people groups and diurnal rhythm was proved existed. Ventricle rhythm of the old groups was slower than other groups during PAF attacks. Before and after PAF， kinds of arrhythmia happened，especially supraventricular arrhythmia. Conclusions The outbreak of PAF depend upon existed heart disease and regulatory factor. It indicated that PAF have close connection with angiocarpy incident.
