Clinical analysis of 19 cases of pregnant women with rapid arrhythmia in the treatment of radiofrequency catheter ablation

Abstract

paroxysmal palpitation, chest tightness, dizziness, and blurred vision. Arrhythmia types: 1 case of atrial flutter and atrial tachycardia, 1 case of atrial flutter and atrial fibrillation, 1 case of atrial fibrillation, 3 cases of supraventricular tachycardia, 1 case of atrial tachycardia and supraventricular tachycardia, 4 cases of ventricular tachycardia, 3 cases of ventricular premature beats and ventricular tachycardia, and 5 cases of atrial tachycardia. All cases were treated by drugs, but all failed 2 cases of them were performed esophageal pacing and cardioversion and also failed.(2)Treatment plan: 19 cases after treatment of arrhythmia, completely terminated, the first 7 patients(from 2002 to 2014)were operated in a small amount of radiation under the guidance, the other 12 patients(after 2015)were carried out in the Ensite NavX mapping system, whichwere operated with zero radiation. Complications and adverse reactions: 1 case of uterine contraction end operation and was gived magnesium sulfate 3 days intravenous inhibition of uterine contractions, 1 case occurred vagal reflex caused by reduced blood pressure and was gived fluid infusion utill normal blood pressure.(3)Maternal and neonatal outcomes: in addition 1 case of pregnancy to give up, the remaining 18 cases were full-term pregnant women, including 4 cases of vaginal delivery and 14 cases of cesarean section. The survival neonates were followed up for 1 to 14 years, average(2.0 ± 2.9)years. The infants were well developed during the follow-up period. Conclution: Radiofrequency catheter ablation is a safe and effective method for the treatment of pregnancy complicated with rapid arrhythmia.
