Overview=
Premature atrial contraction is a common form of supraventricular arrhythmias and mostly the prognosis is good. In rare cases, severe symptoms other than palpitation may occur.
Natural History, Complications and Prognosis
- In general the prognosis of PACs is good, and their occurrence and prognosis is determined by the underlying condition that triggered the PACs.
- In rare cases, a PAC can, like a PVC, trigger a more serious arrhythmia such as atrial flutter or atrial fibrillation.
- Unlike PVC's, PAC's generally do not cause hemodynamic compromise because the conduction throughout the AV node and ventricles is normal, and the filling and contraction of the heart is therefore normal.
