快速性心律失常是临床上最为常见的心律失常,包括阵发性室上性心动过速和阵发性室性心动过速。部分患者在心动过速发作时,可能由于各种原因未能及时记录到心电图,而无法确诊。经食管心房调搏可诱发与复制阵发性室上性心动过速、心房扑动与心房颤动等快速性心律失常,并确定其发生机制与折返途径,为进一步治疗提供依据。经食管心房调搏偶尔也会诱发阵发性室性心动过速,但一般不会诱发心室扑动和心室颤动,除非预激伴快速性房颤蜕变为心室扑动或心室颤动。一.诱发快速性心律失常的方法经食管心房调搏诱发的快速性心律失常绝大多数由折返激动所致, Tachyarrhythmia is the most clinically common arrhythmia, including paroxysmal supraventricular tachycardia and paroxysmal ventricular tachycardia. Some patients in the onset of tachycardia, may not be due to various reasons recorded in time to the ECG, and can not be confirmed. Esophageal atrial pacing can induce and duplicate paroxysmal supraventricular tachycardia, atrial flutter and atrial fibrillation and other tachyarrhythmia, and to determine the mechanism of its occurrence and reentry approach, to provide the basis for further treatment. Transient esophageal atrial pacing occasionally induces paroxysmal ventricular tachycardia, but generally does not induce ventricular flutter and ventricular fibrillation, unless pre-excitation with rapid atrial fibrillation decay into ventricular flutter or ventricular fibrillation. A method of inducing tachyarrhythmia The vast majority of tachyarrhythmia induced by esophageal atrial pacing is caused by reentry stimulation,
