Premature Atrial Contraction

Aka: Premature Atrial Contraction, PAC
  1. Causes
    1. Usually idiopathic and benign
    2. Catecholamine excess
    3. Hypoxia
    4. Myocardial Ischemia
    5. Congestive Heart Failure
    6. Acid-base disturbance
    7. Electrolyte abnormality
  2. Signs: EKG Findings
    1. No compensatory pause
    2. P Wave included in Extrasystole
    3. Associated with right bundle branch
    4. Normal narrow QRS with normal axis

Atrial Premature Complexes (C0033036)

Definition (NCI_CDISC) An electrocardiographic finding of an ectopic impulse originating in the atria and not specifically in the sinus node. The P wave morphology of these complexes is often different from a sinus P wave and the RR intervals preceding these complexes is also shorter than those of the regular beats.

The P wave morphology of these complexes is often different from a sinus P wave and the RR intervals preceding these complexes is also shorter than those of the regular beats. (CDISC)
Definition (MSH) A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.
