   Premature atrial contractions (PACs) are extra heartbeats that start in the upper chambers of your heart. When the premature, or early, signal tells the heart to contract, there may not be much blood in the heart at that moment. That means there’s not much blood to pump out. A pause and a strong beat may follow the extra heartbeat, making it feel l...

   What are atrial premature complexes?

   • Another name for atrial premature complexes is premature atrial contractions. One of the most common symptoms of APCs is heart palpitations or unusual awareness of your heartbeats. Palpitations are heartbeats that are extra fast, extra slow, or irregularly timed. APCs occur when a beat of your heart occurs early in the heart cycle.

   What are premature atrial complexes (PACs)?

   • Premature atrial complexes (PACs) are extra heartbeats in the atria. The atria are two chambers in the heart that receive blood from the veins. PACs are the most common variety of cardiac arrhythmias. This is when the heart beats irregularly, too slow, or too fast. An estimated 50% of all people with or without heart disease have PACs.

   Aug 8, 2023 · Premature atrial contractions (PACs) are contractions of the atria that are triggered by the atrial myocardium but have not originated from the sinoatrial node (SA node). PACs are also commonly referred to as atrial premature complexes (APCs), premature supraventricular complexes, premature supraventricular beat, and premature atrial beat.
