  2. Atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Atrial_fibrillation

    315,000 with atrial flutter (2019) [10] Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11][12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]

  3. Tachycardia-induced cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-induced_cardio...

    antiarrythmic agents, diuretics, catheter ablation, pacemaker [1] Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [1][5] People with TIC may have symptoms ...

  4. Management of atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Management_of_atrial...

    The management of atrial fibrillation (AF) is focused on preventing temporary circulatory instability, stroke and other ischemic events. Control of heart rate and rhythm are principally used to achieve the former, while anticoagulation may be employed to decrease the risk of stroke. [ 1] Within the context of stroke, the discipline may be ...

  5. Lown–Ganong–Levine syndrome - Wikipedia

    en.wikipedia.org/wiki/Lown–Ganong–Levine...

    Individuals with LGL syndrome do not carry an increased risk of sudden death. The only morbidity associated with the syndrome is the occurrence of paroxysmal episodes of tachycardia which may be of several types, including sinus tachycardia, atrioventricular nodal re-entrant tachycardia, atrial fibrillation, or atrial flutter. [4]

  6. Supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    Medications, medical procedures, surgery [5] Frequency. ~3% [6][7][8] Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart. [2]

  7. Sinus node dysfunction - Wikipedia

    en.wikipedia.org/wiki/Sinus_node_dysfunction

    Sinus node dysfunction (SND), also known as sick sinus syndrome (SSS), is a group of abnormal heart rhythms (arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. [1][2] Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which the arrhythmia alternates between fast and slow heart rates.

  8. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation. [1][2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed. [1][3] In general, the ...

  9. Acute decompensated heart failure - Wikipedia

    en.wikipedia.org/wiki/Acute_decompensated_heart...

    Chronic stable heart failure may easily decompensate.This most commonly results from an intercurrent illness (such as pneumonia), myocardial infarction (a heart attack), abnormal heart rhythms (such as atrial fibrillation), uncontrolled high blood pressure, or the person's failure to maintain a fluid restriction, diet, or medication.
