Premature Atrial Contraction

Follow Up Required

Your child participated in a cardiac screening with Who We Play For. An ECG was performed and reviewed by a licensed Cardiologist with specific training on reading ECGs according to the International Criteria.

Initial findings of that ECG indicate that secondary testing is necessary.

What is Premature Atrial Contraction?

Premature atrial contraction (PAC), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common arrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial node and thus triggers a premature heartbeat. In contrast to escape beats, in which the normal sinoatrial node fails, leaving a non-nodal pacemaker to initiate a late beat.

The exact cause of PACs is unclear; while several predisposing conditions exist, single iscolated PACs commonly occur in healthy young and elderly people.

PACs are often completely asymtomatic and may be noted only with Holter monitoring, but occasionally that can be perceived as a sipped beat or a jolt in the chest. In most cases, no treatment other than reassurance is needed for PACs, although medications such as beta blockers can reduce the frequency of symptomatic PACs.

Diagnosis:

Two PACs with a compensatory pause seen on a ECG rhythm strip. A "skipped beat" occurs and rhythm resumes 2 P-to-P intervals after the last normal sinus beat.

Family History: Review detailed family history.

Consult: Pediatric Cardiologist or Electrophysiologist

Your child can continue to participate in the current sports season within school/orgnaization guidelines, but should seek the advice of a Cardiologist for a more detailed examination.
