Atrioventricular Block in Pregnancy: 15.8 Seconds of Asystole

Abstract: Atrioventricular (AV) block in pregnancy is infrequently encountered and there is little management guidance available. We present a case of a 24-year-old G3P1011 at 24 weeks' gestation who presented to the obstetrics and gynecology clinic complaining of palpitations, fatigue, and dyspnea on exertion. Cardiology workup including an electrocardiogram (ECG) and Holter monitor detected second-degree type II (Mobitz) AV block with the longest asystole event lasting 15.8 seconds. A St. Jude's dual-chambe… Show more

“…Atrioventricular block (AVB) is caused by the dysfunction of the cardiac electroconductive pathways and characterized by a prolongation of the PR interval on the electrocardiogram (ECG) [ 10 ]. According to the pattern and feature of the disruption of electrical activity, the blocks are classified in three categories: first degree, second degree (Mobitz type 1 or 2), and third-degree [ 10 , 11 ]. The pathogenesis underlying the block could be an anatomical defect or functional impairment in the heart’s conduction system [ 11 ].…”

“…In such cases, a temporary pacemaker may be placed in the patient. [ 5 ] A routine test such as a 12-lead ECG is often adequate to diagnose a CHB. To diagnose the underlying cause of the electrical abnormality in our patient, we proceeded with a cardiac MRI during the puerperal period.…”

“…Bradycardia in pregnancy due to complete atrioventricular block (CAVB) is a rare but serious occurrence 1 , 2 . The incidence of CAVB is estimated to be 1 in 15 000 to 20 000 live births 3 , and it can be congenital or acquired.…”
