Atrial flutter is the second most common tachyarrhythmia, after atrial fibrillation . (medscape.com)
Catheter ablation in which a physician uses energy to destroy the heart cells causing the tachyarrhythmia. (biotronik.com)
The primary endpoint was atrial tachyarrhythmia recurrence after ablation. (biomedcentral.com)

Secondary endpoints included freedom from any AF and freedom from symptomatic AF at 24 months, cumulative and per visit burden of symptomatic AF, time to first recurrence of AF after the blanking period, and atrial flutter longer than 1 minute. (acc.org)
7,8 Hence, catheter ablation has become widely used for treating symptomatic drug-refractory AF, even though the recurrence rates of AF ablation remain high, especially in persistent AF and longstanding persistent AF. (aerjournal.com)

Atrial Fibrillation(AF) is a cardiovascular disorder that is caused by irregular heartbeat of atria chambers. (skylabs.io)
At Rush, doctors determined she had an irregular heartbeat called atrial fibrillation . (rush.edu)
A common symptom of atrial fibrillation is palpitations or the sensation of an irregular heartbeat, which can be felt in the chest or neck. (drafib.com)

While a normal resting heart rate is 60 to 100 beats per minute (bpm), atrial fibrillation can cause your atria to beat 300 to 600 times per minute. (everydayhealth.com)

Asymptomatic atrial fibrillation can be treated by cardiac monitors like BioMonitor2. (biotronik.com)

In addition to the apparatus used for a "non-complex" ablation, these procedures often make use of sophisticated electro-anatomic mapping systems to localize the source of the abnormal rhythm and to direct delivery of ablation lesions. (wikipedia.org)
Encircling ablation lesions around the pulmonary vein os and a connecting roof line was completed with either an 8mm tip or irrigated RFA catheter. (acc.org)
23-25 Linear ablation combined with PVI may result in reentrant ATs because of conduction gaps and non-transmural lesions caused by ablation lesions. (aerjournal.com)

There are three primary forms of atrial fibrillation: paroxysmal, persistent, and permanent (also called chronic or long standing persistent). (drafib.com)
On the other hand, persistent atrial fibrillation lasts for more than one week and requires medical treatment or intervention to return to normal rhythm. (drafib.com)
Episodes of atrial fibrillation may come and go, or they may be persistent. (seniorhealthcarematters.com)
If you have persistent atrial fibrillation, you'll need treatment such as an electrical shock or medications in order to restore your heart rhythm. (seniorhealthcarematters.com)

This block may also be variable and cause atrial flutter to appear as an irregular rhythm. (medscape.com)
Metabolic conditions such as hyperthyroidism and alcoholism can also cause atrial flutter. (medscape.com)

1] Individuals with muscular dystrophies such as Emery-Dreifuss[2] and myotonic dystrophy[3] may also develop atrial flutter, as well as those with dilated, restrictive, and hypertrophic cardiomyopathies. (medscape.com)

The purpose of the study is to provide data demonstrating the safety and effectiveness of the PulseSelect™ PFA System for the treatment of atrial fibrillation. (vchri.ca)
Prophylaxis and treatment of atrial fibrillation . (ecgwaves.com)

Many people with atrial flutter also have episodes of atrial fibrillation. (msdmanuals.com)

In the fetus, atrial flutter is defined as a rapid regular atrial rate of 300-600 bpm accompanied by variable degrees of atrioventricular (AV) conduction block, resulting in slower ventricular rates. (medscape.com)

Because the AV node cannot conduct at the same rate as the atrial activity, some form of conduction block is often seen, typically 2:1 (most common), 3:1, or 4:1. (medscape.com)
be able to describe the basic mechanisms involved in the pathogenesis of disorders of impulse formation, impulse conduction and cardiac tachyarrhythmias including SVT, atrial fibrillation/flutter, ventricular tachyarrhythmias 4. (aboutdrugspdf.com)
A flutter circuit typically surrounds an anatomical or functional barrier and includes a zone of slow conduction (or conduction over an extended circuit) and an area of unidirectional block, as required for reentry of all types. (medscape.com)

Pulmonary vein isolation remains the cornerstone of atrial fibrillation (AF) ablation. (jafib.com)
3 ]. PV isolation has been the cornerstone of AF ablation. (jafib.com)
At least 20 minutes after finishing the ablation and achieving electrical isolation of the targeted veins, the heart was paced and the ATP/isoproterenol infusion was begun. (afibbers.org)
1 Triggers from the pulmonary vein (PV) have been identified as crucial ectopic sources that initiate AF and pulmonary vein isolation (PVI) is the cornerstone for catheter ablation of AF. (aerjournal.com)

What Is A Cardiac Ablation? (hunterdoncardiovascular.com)

Amiodarone is the most potent antiarrhythmic drug available. (ecgwaves.com)

Background - Refractory ventricular fibrillation (VF) is a challenging clinical entity, for which ablation of triggering premature ventricular complexes (PVCs) is described. (stanford.edu)
If the extra beats come from the top chamber of the heart, they are called premature atrial contractions (PACs). (mayoclinic.org)

Conclusions - VESA is associated with a reduction in the combined endpoint compared with the non-ablation reference group. (stanford.edu)

Antiarrhythmic drugs and/ or beta blocker medication may slow the heartbeat and normalize its rhythm. (biotronik.com)

Initial administration and monitoring of the effect of drugs for treatment of heart rhythm disorders. (wikipedia.org)
They could suggest that you avoid known trigeminy causes, such as caffeine or certain drugs, to see if your heart rhythm returns to normal. (healthline.com)
Atrial Fibrillation is an irregular heart rhythm disorder caused by abnormal electrical impulses from the upper chambers of the heart. (drafib.com)
A person with atrial fibrillation may also have a related heart rhythm problem called atrial flutter. (seniorhealthcarematters.com)

4-6 The recent advances in mapping and ablation techniques have provided more efficient non-pharmacological therapies for AF. (aerjournal.com)
We summarize experimental studies of the role of PITX2 in cardiogenesis and arrhythmogenesis, advances in atrial modelling, and modelling studies for investigating PITX2-dependent AF mechanisms. (encyclopedia.pub)

Atrial flutter is infrequent in children without congenital heart disease. (medscape.com)
The reentrant circuits that occur in children with atrial flutter after congenital heart disease surgery are believed to involve abnormal atrial tissue that has been subject to chronic cyanosis, inflammation secondary to surgery, scarring, and increased wall stress in cases of enlarged atria. (medscape.com)

Nicotine causes atrial fibrosis by blocking the activity of two micro-RNA (mi-R-133 and miR-590), which inhibits transforming growth factor (TGF)-β1 and TGF-β receptor type II, and thus blocks the modulators of connective tissue growth factor. (holisticly.com)

Furthermore, several randomized studies have produced conflicting results regarding the benefit of adding linear ablation lines, CFAE ablation, both or none. (jafib.com)
