Cross-sectional 

研究目的:

本研究旨在研究妊娠晚期BMI对PR间期缩短的影响,探讨BMI是否为PR间期缩短的独立相关因素。同时,比较短PR组与正常PR组的其他心电图参数(如QTc间期、心率等),以评估PR间期缩短对妊娠晚期心脏电生理变化的潜在影响。  

Objectives of Study:

The aim of this study is to investigate the impact of Body Mass Index (BMI) in late pregnancy on the shortening of the PR interval, and to explore whether BMI is an independent correlating factor for PR interval shortening. Additionally, this study will compare other electrocardiographic parameters (such as QTc interval, heart rate, etc.) between the short PR group and the normal PR group to assess the potential effects of PR interval shortening on cardiac electrophysiological changes in late pregnancy.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

Inclusion criteria

1.Women over the age of 20: Pregnant women in the late pregnancy stage (28 weeks of gestation or later).
2.Electrocardiogram records: At least one 12-lead electrocardiogram performed during late pregnancy, including data on PR interval and other electrocardiographic parameters.
3.Pregnancy status: No severe organic heart disease or serious pregnancy complications (e.g., severe preeclampsia), suitable for normal pregnancy monitoring.

排除标准:

1.病理性PR间期缩短:因房室交界性心律、预激综合征等造成的病理性PR间期缩短。
2.器质性心脏病:具有明显器质性心脏病史的孕妇(如心肌病、瓣膜病、先天性心脏病等)。
3.严重妊娠并发症:出现重度先兆子痫或其他严重妊娠期并发症,可能影响心电图结果。
4.不良生活习惯:如有严重抽烟、酗酒史者。
5.伴有严重的心律失常或传导阻滞者:如三度房室阻滞。
6.有精神疾病病史或意识障碍者 。
7.使用影响PR间期的药物者:如β受体阻滞剂、钙通道阻滞剂等。

Exclusion criteria:

1.Pathological shortening of the PR interval: Pathological shortening of the PR interval caused by atrioventricular junctional arrhythmias, preexcitation syndromes, etc.
2.Organic heart disease: Pregnant women with a significant history of organic heart disease (e.g., cardiomyopathy, valvular disease, congenital heart disease, etc.).
3.Severe pregnancy complications: The occurrence of severe preeclampsia or other serious pregnancy complications that may affect electrocardiogram results.
4.Unhealthy lifestyle habits: Such as a history of heavy smoking or alcohol abuse.
5.Severe arrhythmias or conduction blocks: Such as third-degree atrioventricular block.
6.History of mental illness or consciousness disorders.
7.Use of medications affecting the PR interval: Such as beta-blockers, calcium channel blockers, etc.
