The clinical analysis of 212 cases of transesophageal atrial pacing (TEAP) / 中国基层医药

ABSTRACT

Objective To discuss the clinical application value of transesophageal atrial pacing ( TEAP) in basic general hospitals.Methods A total of 212 subjects were selected,with dizziness,syncope,paroxysmal palpita-tions and other clinical symptoms and electrocardiogram showed sinus slow, atrioventricular block, short PR interval period,or with the first urgent symptom of tachycardia.The author doubted these symptoms were due to decreased function of the sinoatrial and atrioventricular node or Paroxysmal Supraventricular Tachycardia (PSVT),and treated them with TEAP with xd-5a.Results 121 cases (57.1%) were positive,83 cases(68.6%) of sinoatrial node dys-function,38 cases(31.4%) of PSVT,then sinoatrial node dysfunction were given atropine load experiment and double checked TEAP.The authors detected 57 cases of non-increased vagus nerve tension in 83 positive cases,29 cases (20.1%) of sinoatrial node hypofunction,8 cases of atrioventricular node hypofunction,14 cases of double node hypofunction,6 cases of tachycardia-bradycardia syndrome;38 cases(31.4%) of PSVT,20 cases of dual atrioven-tricular nodal pathways(DAVNP),12 cases of atrioventricular bypass,4 cases of atrial tachycardia(AT),2 cases of ventricular tachycardia( VT);12 cases from 38 cases of positive results manifested as the first urgent symptom of achy-cardia,included 5 cases of DAVNP,5 cases of atrioventricular bypass,overdrive pacing terminated tachycardia suc-cessfully,2 cases of male VT,1 case terminated tachycardia through giving intravenous amiodarone successfully,1 case was taken electrical cardioversion uccessfully.Conclusion The common causes of slow sinus and atrioventricular block and the common cardiac electrophysiological types of PSVT and VT were detected through TEAP examination with the best diagnostic and differential diagnostic value.According to diagnosis guide,clinicians adopted correct and effective treatment strategies with good clinical application value.The author suggest this methods should be used in clinical,especially in basic general hospitals.
