Premature atrial contractions are contractions in the atria  13 Nov 2019 These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest. Premature 

Premature Atrial Contractions (PACs) Premature Atrial Contractions (PACs) are amongst the most common forms of arrhythmias. It is due to the premature discharge of an electrical impulse in the atrium, causing a premature contraction. My cardiologist just told me I may have PAC. My heart rate went from 125 when it woke me up to 216, called

In contrast, PACs are usually followed by an incomplete pause because the PAC If a PVC occurs early enough (especially if the heart rate is slow), it may 

Arrhythmias are defined as disturbances in heart rate and/or conduction. PAC's represent origination of atrial electrical activity outside the SA node. On the

In most cases, premature atrial contractions aren’t a sign of heart disease and just happen naturally. But some people who have PACs turn out to have related heart conditions, such as
