2. Premature ventricular contraction - Wikipedia

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

   Premature ventricular contractions may be associated with underlying heart disease, and certain characteristics are therefore elicited routinely: the presence of signs of heart disease or a known history of heart disease (e.g. previous myocardial infarction), as well as heart disease or sudden cardiac death in close relatives.

3. Potassium channel blocker - Wikipedia

   en.wikipedia.org/wiki/Potassium_channel_blocker

   Sotalol is indicated for the treatment of atrial or ventricular tachyarrhythmias, and AV re-entrant arrhythmias. Ibutilide is the only antiarrhythmic agent currently approved by the Food and Drug Administration for acute conversion of atrial fibrillation to sinus rhythm. Azimilide; Bretylium; Clofilium; E-4031; Nifekalant [6] Tedisamil; Sematilide

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. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   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 ]

6. Catheter ablation - Wikipedia

   en.wikipedia.org/wiki/Catheter_ablation

   Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.

7. Right atrial enlargement - Wikipedia

   en.wikipedia.org/wiki/Right_atrial_enlargement

   Treatment for RAE can include taking certain medications such as diuretics, beta-blockers, anticoagulants, and anti-arrhythmics. If medications are not effective enough, procedures such as implanting a pacemaker, cardioverter-defibrillator (ICD), or a left ventricular assist device (LVAD), heart valve surgery, and coronary bypass surgery may be ...

8. Catecholaminergic polymorphic ventricular tachycardia - Wikipedia

   en.wikipedia.org/wiki/Catecholaminergic...

   Recently published data suggest that the use of selective beta blockers, such as atenolol, bisoprolol, or metoprolol, is associated with very high treatment failure rates. [ 25 ] Flecainide is a class 1c antiarrhythmic drug that is recommended for those with CPVT who experience abnormal heart rhythms despite taking a beta blocker. [ 2 ]

9. 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).
