Abstract

Disclosed in the present invention is a pacing device for preventing occurrence of atrial fibrillation following premature atrial contraction, including: adjusting values of the number M of atrial events and the number N of premature atrial contraction events to control a pacing control process for preventing the occurrence of atrial fibrillation following premature atrial contraction to take place after a single or more than one premature atrial contraction events, and on the basis of a current p-p′ interval, an atrial safe pacing interval and an average atrial interval, setting a smooth transition pacing sequence. The smooth transition pacing sequence avoids atrial compensation intervals caused by the premature atrial contraction and avoids occurrence of a “short-long-short” sequence. Meanwhile, the number of pacing intervals in the smooth transition pacing sequence is controllably set, and the pacing intervals included sequentially increase and are gradually in transition to the average atrial interval representing a normal atrial interval prior to the occurrence of the premature atrial contraction events, so that the occurrence of the alternation of action potential durations is avoided, and the occurrence of atrial fibrillation caused by the premature atrial contraction is prevented at multiple levels.
