Atrial Premature Contractions in Bigeminy: How Serious Are They?

Atrial premature contractions (APCs) in bigeminy are not necessarily a sign of a serious condition if there is no underlying structural heart disease. However, the presence of bigeminy indicates a significant number of premature beats, which warrants proper medical evaluation and care. In bigeminy, each normal heartbeat is followed by a premature beat, creating a consistent pattern of one normal beat and one early beat.

Diagnosis and Monitoring

To accurately assess the frequency and pattern of premature contractions, a 24-hour Holter monitor is typically recommended. This allows physicians to evaluate the total number of premature beats over a full day and determine whether further treatment is necessary.

When Treatment Is Necessary

If the number of premature beats is high enough to potentially affect heart function, treatment options may be considered. Left untreated, frequent premature contractions could lead to symptoms such as fatigue, dizziness, or palpitations, and in rare cases, may contribute to heart muscle weakness over time.

Non-Surgical Treatment Options

Medications such as beta-blockers, amiodarone hydrochloride tablets, or propafenone hydrochloride can be prescribed to help regulate heart rhythm and reduce the frequency of premature beats. These drugs may be particularly useful for patients who experience symptoms or have a higher risk profile.

Minimally Invasive Procedures

For patients seeking a more permanent solution, catheter ablation is a safe and effective option. This minimally invasive procedure involves guiding a catheter through the blood vessels to the heart, where it locates and eliminates the specific area causing the premature beats using radiofrequency energy. Ablation can offer long-term or even permanent relief from atrial premature contractions in bigeminy.
