2. Premature atrial contraction - Wikipedia

   en.wikipedia.org/wiki/Premature_atrial_contraction

   Normal sinus rhythm and ectopic beats - premature ventricular contractions (PVC) and premature atrial contractions (PAC) shown on an EKG. Premature atrial contractions are typically diagnosed with an electrocardiogram, Holter monitor, long-term continuous monitor, cardiac event monitor, or with a smartwatch with an ECG functionality. [citation ...

3. Atrial tachycardia - Wikipedia

   en.wikipedia.org/wiki/Atrial_tachycardia

   Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.

4. Ectopic beat - Wikipedia

   en.wikipedia.org/wiki/Ectopic_beat

   It is a form of cardiac arrhythmia in which ectopic foci within either ventricular or atrial myocardium, or from finer branches of the electric transduction system, cause additional beats of the heart. Some medications may worsen the phenomenon. [citation needed] Ectopic beats are considered normal and are not indicative of cardiac pathology.

5. Bigeminy - Wikipedia

   en.wikipedia.org/wiki/Bigeminy

   When the atrial rhythm is irregular (as in atrial fibrillation or sinus arrhythmia) the presence of bigeminy depends on the length of the P–P interval and happens more frequently with a longer interval. As with post PVC pauses, a longer P–P interval leads to a higher chance of re-entrant circuits and thus PVCs.

   Tachycardia. A faster-than-normal heart rate. Bradycardia. A slower-than-normal heartbeat. Atrial fibrillation (A-fib). An irregular and often very fast heart rate. Premature ventricular ...

7. Premature ventricular contraction - Wikipedia

   en.wikipedia.org/wiki/Premature_ventricular...

   Normal sinus rhythm and ectopic beats - premature ventricular contractions (PVC) and premature atrial contractions (PAC) shown on an EKG. PVCs may be found incidentally on cardiac tests such as a 12-lead electrocardiogram (ECG/EKG) performed for another reason. In those with symptoms suggestive of premature ventricular complexes, the ECG/EKG is ...

8. Premature heart beat - Wikipedia

   en.wikipedia.org/wiki/Premature_heart_beat

   A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...

9. Wandering atrial pacemaker - Wikipedia

   en.wikipedia.org/wiki/Wandering_atrial_pacemaker

   Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. [1] This is different from normal pacemaking activity, where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm.
