• In this video I show you the difference between a PAC, PVC, and a PJC. Here is an overview of what I cover: - PAC is when you have a contraction (P, QRS, T) that starts right after you have already had a full contraction. - A PVC, is when you have a QRS complex that is greater than 0.12 seconds.


  • 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.

    Beside above, how do you treat PVC and Pac? Treatment

    1. Lifestyle changes. Eliminating common PVC triggers — such as caffeine or tobacco — can decrease the frequency and severity of your symptoms.
    2. Medications. Beta blockers — which are often used to treat high blood pressure and heart disease — can suppress premature contractions.
    3. Radiofrequency catheter ablation.

    Consequently, what is a PAC and PVC?

    A premature contraction can originate in your hearts upper (atria) or lower (ventricles) chambers. Premature beats that start in your hearts upper chambers are premature atrial contractions, or PACs. Those that start in the lower chambers are premature ventricular contractions, or PVCs.

    Do PACs and PVCs feel different?

    The premature beat may feel different from a normal heartbeat because little or no blood is being pumped out of your heart. PACs and PVCs are common and often harmless. You can experience occasional PACs or PVCs without having bigeminy.
