有些作者提出健康妇女在妊娠期间室上型快速性心律失常的发生率增加。另有些报导指出妊娠可以使无症状W.P.W综合征患者促发室上型快速性心律失常。本文报告3例,年龄在21-31岁。妊娠前心电图均证实有W.P.W综合征,但未出现症状及心律失常。在妊娠中晚期均先后出现心悸,胸痛、头晕及晕厥,心电图证实阵发性室上型心动过速。经用奎宁丁、异搏定、氨酰心安等治疗效果良好,产后随访8个月至2.5年未再出现心律失常。讨论:W.P.W综合征在正常人群中发病率为0.01%——0.3%。在患有W.P.W综合征人群中阵发性心动过速的发病率在青年人约为10%,随年龄增加可达36%。妇娠期W.P.W综合征的确切发病率尚不清楚。但一些报告及本文表明妊娠可促发原来无症状的W.P.W综合征患者出现快速型心律失常.
Some authors have suggested that healthy women have an increased incidence of supraventricular tachyarrhythmia during pregnancy. Other reports indicate that pregnancy can promote asymptomatic W.P.W syndrome patients with supraventricular tachyarrhythmia. This article reports 3 cases, aged 21-31 years old. Pre-pregnancy ECG confirmed W.P.W syndrome, but no symptoms and arrhythmia. Palpitations, chest pain, dizziness and fainting have occurred in the second and third trimester of pregnancy. ECG confirmed paroxysmal supraventricular tachycardia. After treatment with quinidine, verapamil, atenolol and other good treatment, postpartum follow-up of 8 months to 2.5 years no recurrence of arrhythmia. Discussion: The incidence of W.P.W syndrome in the normal population is 0.01% to 0.3%. The incidence of paroxysmal tachycardia in people with W.P.W syndrome is about 10% in young people and up to 36% with age. The exact incidence of W.P.W syndrome during pregnancy is not clear. However, some reports and this article show that pregnancy triggers tachyarrhythmia in previously asymptomatic patients with W.P.W syndrome.
