Abstract

BACKGROUND: Arrhythmias are reported during pregnancy, although hospitalization for these infrequent events is not fully characterized. The frequency and outcome of arrhythmias during pregnancy are unknown. METHODS: Between 1992 and 2000, there were 136,422 pregnancy-related admissions to Parkland Memorial Hospital (Dallas, TX, USA). Using the discharge diagnosis data bank and the International Classification of Disease, 9th revision, Clinical Modification (ICD-9-CM) coding system, we identified 226 admissions (218 patients) where cardiac arrhythmias and intrauterine pregnancy were both reported. RESULTS: The most common rhythm disturbances during pregnancy were sinus tachycardia (ST), sinus bradycardia (SB), or sinus arrhythmia (SA) (104 episodes/100,000 pregnancies). This was followed by paroxysmal supraventricular tachycardia (PSVT) and premature beats, with a frequency of 24/100,000 and 33/100,000, respectively. Paroxysmal supraventricular tachycardia occurred most frequently in the third trimester or peripartum. All episodes terminated spontaneously or were safely terminated with medical therapy. Advanced heart block or lethal arrhythmias were exceedingly rare during pregnancy. CONCLUSION: Most frequently reported cardiac arrhythmias in pregnancy are benign and do not require intervention. Supraventricular tachycardia (SVT), being one of the most common complicated cardiac arrhythmias during pregnancy, can be treated effectively and safely with standard medical therapy. Ventricular arrhythmias or high-degree atrioventricular block (AVB) during pregnancy are extremely rare. Cardiac arrest is also rare, and is often caused by a different etiology from the conventional ones for sudden cardiac death.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
