Key result
Normal pregnancy was associated with a low prevalence of rhythm disturbances, most commonly ventricular premature contractions (1.8%), and the development of new T-wave inversions in 8.2% of women.
Why the study?
Understanding physiologic changes and types of arrhythmias during pregnancy can help identify cases that require intervention.
Observational (n=450)
No
Minor electrocardiographic changes, such as reduction in QRS axis, T-wave inversion, and prolonged QTc, as well as rare rhythm disturbances like VPCs, can be considered normal in pregnancy unless associated with significant symptoms.
No takes yet. Share an insight, caveat, or question.
Supports viewing minor ECG changes as benign in asymptomatic pregnancy; extends observational data but leaves open validation in symptomatic women.
Sharma et al. (2020) conducted an observational in Normal pregnancy (n=450). Normal pregnancy was evaluated on Prevalence and types of electrocardiography changes and cardiac arrhythmias. Normal pregnancy was associated with a low prevalence of rhythm disturbances, most commonly ventricular premature contractions (1.8%), and the development of new T-wave inversions in 8.2% of women.
