Typical atrialflutter commonly occurs in patients with atrial fibrillation (AF). Limited information exists regarding the effects of concurrent atrialflutter on the long-term outcomes of rhythm control. The data were obtained from a multicenter registry of cryoballoon ablation for AF ( n = 2,689).
Outcomes of ablation with the FARAPULSE PFA System – a nonthermal treatment in which electric fields selectively ablate heart tissue – will be compared to outcomes following use of anti-arrhythmic drug (AAD) therapy, which is commonly prescribed for patients living with persistent AF. The company now anticipates U.S. Circulation.
ABSTRACT Atrialflutter (AFL), defined as macro-re-entrant atrialtachycardia, is associated with debilitating symptoms, stroke, heart failure, and increased mortality. Atypical AFL is a heterogenous group of re-entrant atrialtachycardias that most commonly occur in patients with prior heart surgery or catheter ablation.
She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. The ECG was interpreted as showing atrialflutter with 2:1 conduction. Answer : The ECG above shows a regular wide complex tachycardia. The heart rate could be compatible with that of a 2:1 conducted atrialflutter.
Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrialflutter (AFL), and atrialtachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).
Cheng and Zhang to our paper1, we note that despite ARVC being a relatively uncommon cardiomyopathy, we uniquely report on a large clinical experience with very long-term follow-up after VT ablation and confirm a high incidence of atrialflutter (AFL) and the effectiveness and low risk of catheter ablation of AFL.
Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups. vs 81.5%, p=0.02). 95% CI 0.19
When mutiple atrialtachycardias coexist, ablation of an individual isthmus may lead to a seamless transition (without significant changes in surface ECG or coronary sinus activation) to a second rhythm. The isthmus block could go unnoticed leading to continued unnecessary ablations.
Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.
The positive F wave in lead V1 changed during entrainment from the right atrial appendage (RAA) during typical atrialflutter (AFL). Abstract Introduction Typical atrialflutter (AFL) is a macroreentrant tachycardia in which intracardiac conduction rotates counterclockwise around the tricuspid annulus.
This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? To me, it was clearly atrialflutter with 1:1 conduction. The rate of 280 is just right for atrialflutter. The waves look like atrialflutter waves, NOT like a wide ventricular complex.
Introduction:Supraventricular tachycardia (SVT) is common and poorly tolerated in patients who have undergone Fontan procedure. Recurrence rates after catheter ablation in these patients are high. Ablation success rate was 92%. AtrialTachycardia (70%) and Typical AtrialFlutter (65%) were the most common SVTs ablated.
In all probability, this dilation is a form of atrialtachycardia and atrial cardiomyopathy. However, underlying lesions such as hypertension, mitral valve disease, COPD, ASD, and TR greatly influence the degree of atrial enlargement. We know atrialflutters can be confined to one atrium.

FAAM ablation successfully decreased the recurrence rate of atrial tachyarrhythmia compared with conventional non-PV foci ablation. Abstract Introduction Treatment of recurrent atrial fibrillation (AF) is sometimes challenging due to non-pulmonary vein (PV) foci. The RHYTHMIA system was used to perform all the procedures.
Abstract The QDOT MICRO™ Catheter is a novel open-irrigated contact force-sensing radiofrequency ablation catheter. It offers very high-power short-duration (vHPSD) ablation with 90 W for 4 s to improve safety and efficacy of catheter ablation procedures.
BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. This study aimed to evaluate a short-term anti-inflammatory treatment with colchicine following ablation of AF.METHODS:Patients scheduled for ablation were randomized to receive colchicine 0.6 2.02];P=0.89). 1.99];P=0.55).CONCLUSIONS:Colchicine
Abstract Background Dofetilide is a class III antiarrhythmic agent approved for the treatment of atrial fibrillation and atrialflutter. Given the efficacy of other class III agents, it has been used off-label for the treatment of premature ventricular complexes (PVCs) and ventricular tachycardias (VTs).
Abstract Introduction Atrial fibrillation and atrialflutter originating from the donor s heart is a commonly reported complication post heart transplant. Case A 47-year-old male presented with atrialtachycardia 6 months post heart transplant.
We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrialflutter with regular conduction. There are no P waves preceding the QRS complexes, and no clear flutter waves.
PEARL # 3: AtrialFlutter with 1:1 AV conduction is rare! Since the rate of atrial activity with flutter in adults is most often very close to 300 /minute ( ie, usual range for atrial activity ~250-350/minute ) — AFlutter with 2:1 AV conduction typically results in a regular ventricular rate of ~140-160/minute.
Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology. Read about Fascicular VT here: Idiopathic Ventricular Tachycardias for the EM Physician Case Continued He was completely stable, so adenosine was administered. See Learning point 1 below.
The principal d ifferential d iagnosis i s similar to what we derived in the October 16, 2019 Case : i ) Sinus Tachycardia ; ii ) Reentry SVT ( either A VNRT if the reentry circuit is contained within the normal AV nodal pathway — or A VRT if an accessory pathway is involved ) ; iii ) AtrialTachycardia ; or iv ) AtrialFlutter.
a global leader in cardiac arrhythmia treatment and part of Johnson & Johnson MedTech , today announced European CE mark approval of the VARIPULSE Platform for the treatment of symptomatic drug refractory recurrent paroxysmal atrial fibrillation ( AF ) using pulsed field ablation (PFA).
ABSTRACT Introduction The safety and efficacy of paroxysmal atrial fibrillation (PAF) ablation with the HELIOSTAR multielectrode radiofrequency (RF) balloon catheter have been demonstrated in European studies; data from elsewhere are lacking.

PurposeAtrial tachycardia is an uncommon supraventricular tachycardia in children. It is often drug-resistant and likely to occur concomitantly with tachycardia-induced cardiomyopathy, making radiofrequency catheter ablation the preferred treatment. A total of 78.6% No postoperative complications occurred in any patient.
ABSTRACT Typical atrialflutter (AFL), defined as cavotricuspid isthmus (CTI)-dependent macro-re-entrant atrialtachycardia, often causes debilitating symptoms, and is associated with increased incidence of atrial fibrillation, stroke, heart failure, and death.
This sub-analysis from the Cryo Global Registry sought to investigate predictors of ablation success after PVI using cryoballoon ablation (CBA) for PsAF. Methods and Results ATA recurrence was defined as 30s recurrence of atrial fibrillation, atrialflutter or atrialtachycardia after a 90-day blanking period and through 12-months.
During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). The patient has been scheduled for a PVC ablation procedure. This patient very likely has some form of idiopathic ventricular tachycardia. Potassium and magnesium serum levels were normal.
Figure-1: While at first glance the rhythm in Figure-1 might be mistaken for sinus tachycardia in fact, this is not the rhythm. Instead there is 2:1 atrial activity that is best seen in lead V1 ( See Figure-2 ). However, having noticed the 2:1 atrial activity in lead V1 I was not at all convinced that the episode was VT.
