Premature Atrial Contractions (PACs)

ICD-10 Code
I49.1

Clinical Criteria for Premature Atrial Contractions (PACs).

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with intermittent palpitations described as "skipped beats," "fluttering," or "thumping" in the chest. Symptoms are episodic, occurring at rest or during periods of stress/caffeine intake. No associated syncope, presyncope, chest pain, or dyspnea. No history of structural heart disease or thyroid dysfunction.

Clinical Examination Findings

Cardiovascular exam reveals a regular rhythm interrupted by occasional premature beats followed by a compensatory pause. Heart sounds S1 and S2 are normal; no murmurs, rubs, or gallops. Peripheral pulses are regular with occasional early beats. No jugular venous distension or peripheral edema noted.

Treatment Protocol

Management focuses on identifying and eliminating triggers (caffeine, alcohol, nicotine, stress). If symptomatic and persistent, consider beta-blockers (e.g., metoprolol or bisoprolol) to suppress ectopy. Monitor via Holter or event monitor if frequency increases. Reassurance provided regarding the benign nature of isolated PACs in the absence of structural heart disease.
