Background Hypertrophic cardiomyopathy (HCM) is commonly associated with atrialfibrillation (AF), but its impact on outcomes in real-world practice is uncertain. The aim of the study was to evaluate the clinical profile and prognosis of patients with HCM and AF. Methods Overall, 1739 adult patients with HCM (40.9% of the patients.
So it must be atrialfibrillation. Then I always look to see if the initial deflection of the QRS has a lot of voltage change per change in time (seen in tachycardias that are initiated from above the ventricle because the propagate through fast conducting purkinje fiber. Pacemaker mediated tachycardia!
male with pertinent past medical history including Atrialfibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Description : Regular Wide Complex Tachycardia at a rate of about 160.
Here is her ECG: Regular Wide Complex Tachycardia. Regular means it can't be atrialfibrillation --Most regular wide complex tachcardia are VT, especially if the patient has poor LV function, as in this case. Could it be atrialtachycardia with RBBB and LPFB aberrancy? What do you think? What do you want to do?
The ECGs show a wide complex, irregularly irregular tachycardia. The differential of wide complex irregularly irregular includes: polymorphic VT, atrialfibrillation with WPW, atrialfibrillation with other aberrancy. Thus, the patients rhythm is atrialfibrillation with WPW.
Scar-related re-entrant atrialtachycardias and atrialfibrillation (AF) are the most common types of AA, but focal atrialtachycardias, atrioventricular re-entrant tachycardia using an accessory pathway and atrioventricular nodal re-entrant tachycardia are also encountered.
The collaboration, according to a written statement issued by the company, aims to address challenges in capturing and analyzing cardiac signals to help physicians enhance patient outcomes for atrialfibrillation procedures. Estimates of current and future incidence and prevalence of atrialfibrillation in the U.S.
The trial will evaluate the outcomes of therapy provided with the FARAPULSE PFA System versus AADs, including device-or procedure-related adverse events, the rates of freedom from AF, atrial flutter, or atrialtachycardia, as well as AF burden – a measurement of the amount of AF an individual experiences. Circulation.
When atrialfibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. A fibrillatory wave that occurs at a rate of more than 600 beats per minute can cause fatigue in the long run, leading to atrial dilation.
The most common presenting complaints and ECG abnormality were trauma (44%) and sinus tachycardia (15%), respectively. Data were taken from patients medical notes.ResultsThe final analysis included 694 patients, 101 (15%) had AF on the ECG.
But it is not disorganized enough to be polymorphic ventricular tachycardia. The rhythm is therefore atrialfibrillation with WPW until proven otherwise. Learning Points: Wide complex irregularly irregular tachycardias include PMVT, AF with WPW, and AF with aberrancy. What do you want to do? Smith : I always cardiovert.
A prehospital 12-lead was recorded: There is a regular wide complex tachycardia. The computer diagnosed this as Ventricular Tachycardia. There is a wide complex regular tachycardia at a rate of 226. Toothache, incidental Wide Complex Tachycardia Could it be fascicular VT or Bundle Branch VT ( i.e., idiopathic VT )?
Clinical introduction A woman in her 60s with non-obstructive coronary artery disease, aortic valve replacement and aortic arch repair, chronic diastolic heart failure and paroxysmal atrialfibrillation (AF) and flutter (AFL), presented with 3 days of sustained palpitations that felt similar to prior episodes of AF/AFL.
A patient in the ICU with significant underlying cardiac disease [HFrEF 30%, non-ischemic cardiomyopathy, LBBB s/p CRT-D (biventricular pacer), AVNRT s/p ablation a few yrs ago, hx sinus tachycardia while on max tolerated BB therapy] went into a regular wide-complex tachycardia after intubation for severe COPD exacerbation. What to do?
Here is the computer interpretation: ATRIALFIBRILLATION WITH RAPID VENTRICULAR RESPONSE WITH ABERRANT CONDUCTION OR VENTRICULAR PREMATURE COMPLEXES LEFT AXIS DEVIATION [QRS AXIS beyone -30] NONSPECIFIC ST and T-WAVE ABNORMALITY The over-reading physician confirmed this diagnosis, which is incorrect. It is not atrialfibrillation.
She also has a hx of paroxysmal atrialfibrillation and is on oral anticoagulant treatment. She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Cardiac output (CO) was being maintained by the tachycardia.
AF Often Asymptomatic: Even for atrialfibrillation (AF)the most commonly symptomatic arrhythmiaover half of all cases were asymptomatic. Its estimated that undiagnosed atrialfibrillation alone costs the U.S. $3 Long-term outcome of non-sustained ventricular tachycardia in structurally normal hearts. 2016;11(8).
Epicardial Marshall bundle (MB) are frequently utilized in left atrialtachycardias (LATs) post atrialfibrillation (AF) ablation with pulmonary vein isolation and substrate modification.
Abstract Introduction Some previous studies have reported that a first-step ethanol infusion into the vein of Marshall (EIVOM) with touch-up radiofrequency (RF) ablation can facilitate mitral isthmus (MI) block and improves the ablation outcomes in persistent atrialfibrillation (PeAF) patients. 0.78, p = .006).
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare disorder presenting as exercise-induced ventricular arrhythmias, rarely associated with mutations in triadin (TRDN).
Biatrial atrialtachycardia (BiAT) is a rare form of atypical macro-reentrant AT (MRAT) that can be difficult to characterize and ablate. Ablation of regions demonstrating spatiotemporal dispersion (SD) has shown a high rate of atrialfibrillation (AF) termination to either sinus or MRAT during ablation.
Introduction A high recurrence rate of atrialfibrillation was monitored after catheter ablation for persistent atrialfibrillation. The results will evaluate sacubitril/valsartan as a novel treatment for improving prognosis and a complement to conventional drug therapy.
The two ECGs above were texted to me with the text: "Young Guy came in in SVT but now in and out of irregular wide complex tachycardia. -- not sure if polymorphic VT vs. a fib with WPW." Definitely atrialfibrillation. Probably WPW but is very slow for atrial fib withWPW. So this looks like WPW with Atrialfibrillation.
It is not uncommon for several different abnormal changes to occur simultaneously in an ECG, as in this Holter ECG strip. The explanation of the visible ECG changes can be found in the 2nd image
Ablation of regions demonstrating spatiotemporal dispersion (SD) has been demonstrated as an alternative strategy beyond pulmonary vein isolation in patients with persistent atrialfibrillation. Occurrence of atrialtachycardia (AT) following ablation remains a limitation of this approach.
The goal of the AFLOAT trial was to compare the efficacy of flecainide compared with standard of care in preventing atrialfibrillation (AF) post-patent foramen ovale (PFO) closure.
A woman in her mid-60s with a history of paroxysmal atrialfibrillation and hypertension presents with 3 days of nausea, vomiting, and diarrhea. What would you do next?
Typical atrial flutter commonly occurs in patients with atrialfibrillation (AF). Limited information exists regarding the effects of concurrent atrial flutter on the long-term outcomes of rhythm control. All the patients with typical atrial flutter underwent CTI ablation. vs. 29.9%, p < 0.001).
At the top you can see a broad complex tachycardia without recognizable P waves, which ends spontaneously after 2 beats in the lower section. After the end of the VT in the 2nd strip, a narrow QRS complex appears, here you can also recognize that atrialfibrillation is present. This is a VT.
However, widely split P' waves in focal atrialtachycardia (AT) on a surface electrocardiogram (ECG) have rarely been reported. Case summary A 67-year-old patient, who had undergone two radiofrequency ablations for atrialfibrillation, presented with recurrent palpitation.
Whenever it is this fast, you need to be very careful to ascertain whether it is irregular ( as in atrialfibrillation with rapid ventricular respsonse ) or regular ( as in VT ). This is not because it is polymorphic VT; it is because it is WPW with atrialfibrillation. Atrialfibrillation/flutter in pre-excitation.
Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrialfibrillation (AF), atrial flutter (AFL), and atrialtachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).
Patients with ICDs who experience atrialfibrillation (AF) have a higher risk of stroke, heart failure, and mortality. Therefore, early detection and management of atrialfibrillation (AF) are crucial in these patients.
Backgroundwide antral pulmonary vein isolation (PVI) is effective for treating paroxysmal atrialfibrillation (PAF), although time-demanding. Procedural data and electrophysiology (EP) laboratory times were systematically collected and analyzed.
Ioannis Katsoularis, image courtesy of Klas Sjöberg milla1cf Thu, 12/14/2023 - 09:23 December 14, 2023 — Individuals infected with COVID-19 are also at an increased risk of suffering from heart rhythm disturbances, such as atrialfibrillation.
Vein of Marshall ethanol ablation (VOM-EA) as an adjunct to pulmonary vein isolation (PVI) has been reported to improve freedom from atrialfibrillation (AF) and atrialtachycardia (AT).
An otherwise healthy woman in her 20's with no past medical history presented with tachycardia. The rhythm is irregularly irregular, therefore it is atrialfibrillation 2. The complexes are wide (so one might think of atrialfibrillation with aberrancy, in which case you should see RBBB or LBBB pattern, which is not there) 3.
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 atrialfibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups.
Abstract Introduction Atrialfibrillation and atrial flutter 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.
PMH: Known paroxysmal Atrial fib. He is usually is in sinus rhythm as far as he knows, but he cannot subjectively feel atrialfibrillation, so he is never completely certain when he is in sinus or atrial fib. Here is his ECG: Atrial Fib with a Ventricular Response of about 66. He immediately completely recovered.
Commonly employed empiric strategies for catheter ablation (CA) of refractory atrialfibrillation (AF) beyond pulmonary vein isolation (PVI) include posterior wall isolation (PWI), linear ablation involving left atrial (LA) roof and mitral lines, as well as targeting of areas of low voltage / myopathy.
The pacing delivered during the atrial relative refractory period, which is also known as the “vulnerable period,” can result in pacemaker-induced atrialtachycardias, or as in our case atrialfibrillation (AF).
Frequent premature ventricular contractions (PVCs) and nonsustained ventricular tachycardia (NSVT) have been associated with cardiovascular disease and mortality. Their prevalence, especially in ambulatory populations, is under-studied and limited by few female participants and the use of short-duration (24-48 hour) monitoring.
