None:
The incidence of premature atrial contractions (PAC) in a structurally normal heart can result in clinically significant consequences, including arrhythmias, increased risk of all-cause mortality, and the development of PAC-induced cardiomyopathy. In a patient with an otherwise normal heart, it is essential to consider the patient's age, the presence of symptoms, and the PAC frequency when deciding whether treatment is warranted and when to initiate it. This review aims to assess the clinical significance of PACs in a normal heart and discuss the optimal timing and strategy for treatment.
