  2. Ectopic beat - Wikipedia

    en.wikipedia.org/wiki/Ectopic_beat

    Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

  3. 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 ...

  4. 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 ...

  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.

  6. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    A premature atrial pacemaker has a regular underlying rhythm however there is a premature beat which can be identified by an irregular p wave with a different size, shape, and direction often found within a T wave, the PR interval is generally normal however can be hard to measure, the QRS complex is premature for the PAC, but is generally normal.

  7. Palpitations - Wikipedia

    en.wikipedia.org/wiki/Palpitations

    Abnormal heart rhythms (ectopic beat, premature atrial contraction, junctional escape beat, premature ventricular contraction, atrial fibrillation, supraventricular tachycardia, ventricular tachycardia, ventricular fibrillation, heart block). Pectus Excavatum, also known as funnel chest, is a chest wall deformity.

  8. 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.

  9. Holiday heart syndrome - Wikipedia

    en.wikipedia.org/wiki/Holiday_heart_syndrome

    Holiday heart syndrome, also known as alcohol-induced atrial arrhythmias, is a syndrome defined by an irregular heartbeat and palpitations [1] associated with high levels of ethanol consumption. [2] Holiday heart syndrome was discovered in 1978 when Philip Ettinger discovered the connection between arrhythmia and alcohol consumption. [ 3 ]
