What is a PAC rhythm?

Premature atrial contractions (PACs), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria.

Considering this, are PACs dangerous?

About PACs Premature atrial contractions (PACs) are premature heartbeats that are similar to PVCs, but occur in the upper chambers of the heart, an area known as the atria. PACs do not typically cause damage to the heart and can occur in healthy individuals with no known heart disease.

Likewise, what causes PAC? But these things can make PACs more likely:

  • Pregnancy.
  • High blood pressure, heart disease, or hyperthyroidism.
  • Stress or fatigue.
  • Caffeine.
  • Alcohol.
  • Smoking.
  • Cold or hay fever medicine.
  • Asthma medicine.

Additionally, are PACs normal?

Premature atrial complexes, or PACs, are “extra” heartbeats that arise within the atria of the heart. PACs are the most common variety of cardiac arrhythmia. In fact, PACs are so common that most people will have them occasionally.

Do PACs lead to AFIB?

PACs are premature heartbeats which originate in the atria, or the two upper chambers of the heart. In the subset of 1,260 participants without previously diagnosed atrial fibrillation, those who had a higher PAC count – or more contractions – had an 18 percent increased risk for developing atrial fibrillation.
