Abstract：Objective To explore the clinical value of the regularity of outbreak and the diurnal rhythm of paroxysmal atrial tachycardia. Methods The DCG was used to analyse the regularity of outbreak and the diurnal rhythm of paroxysmal atrial tachycardia in 366 patients. Results The incidence rate of paroxysmal atrial tachycardia was the highest in patients with coronary heart disease（55.2%），and the rates was increased by age increasing，the elder group was the highest while compared with other groups（P <0.01）. The diurnal rhythm was found on those with paroxysmal atrial tachycardia. Conclusion Atrium muscle depolarization velocity incongruous on patients with coronary heart disease is favorable for the incidence of paroxysmal atrial tachycardia affected by myocardial ischemia，hypoxia，inflammation，denaturalization and fibrosis. Detection rate is increased by age increasing which is result from the changing of automaticity，excitory，conductibility of the heart induced by myocardial degenerative. The diurnal rhythm of paroxysmal atrial tachycardia was proved to been effected to by vegetative nerve.
