[Sinus tachycardia in pregnancy]

Area of Science:

• Cardiology
• Maternal-Fetal Medicine

Background:

• Sinus tachycardia often has a clear cause, but inappropriate sinus tachycardia (IST) is considered when no etiology is identified.
• IST management focuses on alleviating patient symptoms.

Purpose of the Study:

• To highlight the rare but serious risk of tachycardia-induced cardiomyopathy during pregnancy.
• To emphasize the need for prompt diagnosis and treatment of tachycardia in pregnant women.

Main Methods:

• Review of clinical considerations for sinus tachycardia and IST.
• Discussion of management strategies for tachycardia in pregnancy.
• Reference to diagnostic recommendations in Denmark.

Main Results:

• Tachycardia-induced cardiomyopathy in pregnancy, though rare, progresses rapidly and requires urgent intervention.
• Electrocardiogram screening is advised for pregnant women experiencing palpitations or persistent heart rates exceeding 100 bpm.

Conclusions:

• Prompt evaluation and management of tachycardia are crucial in pregnant women to prevent severe cardiac complications.
• Early detection through electrocardiogram can mitigate risks associated with heart rate abnormalities during gestation.
