  2. Catheter ablation - Wikipedia

    en.wikipedia.org/wiki/Catheter_ablation

    Recurrence of atrial fibrillation within three months of an ablation is seen in most patients, but many of those patients become free of atrial fibrillation in the long term. [17] For this reason the first three months after an ablation are described as the "blanking period," during which no further intervention is to be attempted. [17]

  3. Atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Atrial_fibrillation

    Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]

  4. First-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/First-degree_atrio...

    It was originally thought of as having a benign prognosis. In the Framingham Heart Study, however, the presence of a prolonged PR interval or first degree AV block doubled the risk of developing atrial fibrillation, tripled the risk of requiring an artificial pacemaker, and was associated with a small increase in mortality. This risk was ...

  5. Left atrial appendage occlusion - Wikipedia

    en.wikipedia.org/wiki/Left_atrial_appendage...

    The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.

  6. Supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    Atrial fibrillation: Red dots show atrial fibrillation activity. Atrial fibrillation meets the definition of SVT when associated with a ventricular response greater than 100 beats per minute. It is characterized as an "irregularly, irregular rhythm" both in its atrial and ventricular depolarizations and is distinguished by its fibrillatory ...

  7. Emergency Severity Index - Wikipedia

    en.wikipedia.org/wiki/Emergency_Severity_Index

    The Emergency Severity Index (ESI) is a five-level emergency department triage algorithm, initially developed in 1998 by emergency physicians Richard Wurez and David Eitel. [1] It was previously maintained by the Agency for Healthcare Research and Quality (AHRQ) but is currently maintained by the Emergency Nurses Association (ENA).

  8. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    Atrial fibrillation and atrial flutter resulted in 112,000 deaths in 2013, up from 29,000 in 1990. [10] However, in most recent cases concerning the SARS-CoV‑2 pandemic, cardiac arrhythmias are commonly developed and associated with high morbidity and mortality among patients hospitalized with the COVID-19 infection, due to the infection's ...

  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.
