BackgroundAtrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide, posing significant health burdens. The number of publications increased rapidly from 2019 to 2024, with a notable surge occurring after 2022. The most productive journals were Europace and the Journal of Interventional Cardiac Electrophysiology.
As I have discussed the user-friendly and time-efficient criteria I favor for distinction between VT vs SVT rhythms ( with either preexisting BBB or aberrant conduction ) — I'll refer those interested in more detail to My Comments in the May 5, 2020 — the April 2, 2022 — and the February 14, 2022 posts in Dr. Smith's Blog.
Procedural data and electrophysiology (EP) laboratory times were systematically collected and analyzed. Upper limit skin-to-skin time and missed FPI resulted predictors of the primary endpoint.ConclusionThis standardized workflow resulted in low procedural times and arrhythmias recurrence without compromising the safety.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. The aim of this study is to define the diagnostic yield of a large gene panel with ACMG variant classification and to assess prognosis of SCN5A and non-SCN5A variants.METHODS:All patients with BrS, were prospectively enrolled in the UZB registry between 1992 and 2022.
Circulation: Arrhythmia and Electrophysiology, Volume 16, Issue 11 , Page e012191, November 1, 2023. METHODS:Retrospective cohort study of patients <21 years of age with HCM/preexcitation from 2000 to 2022. METHODS:Retrospective cohort study of patients <21 years of age with HCM/preexcitation from 2000 to 2022.
This could be easily overlooked since there is complete heart block, but recognizing the atrial arrhythmia may mean prescribing anticoagulation to prevent stroke. The October 21, 2022 post — for " artifactual VT". In this case, it is atrial fibrillation. Figure-1: I've labeled the artifact in today's initial ECG.
He has a family history concerning for arrhythmia. Given the circumstances of his car crash, we presume it was due to an underlying arrhythmia. 2 weeks Here is the final electrophysiology note: It is unclear what precipitated his motor vehicle collision.
Outcome Electrophysiologic study showed an accessory pathway (WPW, antidromic AVRT) Why did adenosine not work? PEARL #1 : Getting an Echo when your arrhythmia patient is stable can sometimes prove highly insightful for determining the rhythm. 6 mg often does not work, but especially in low flow states.
Patient was referred to electrophysiologic testing due to suspicion of afib and WPW. During electrophysiologic testing AVRT was induced, which degenerated to afib with ortho and antidromic conduction. What I found especially interesting about this arrhythmia — is the variation in QRS morphology throughout.
milla1cf Fri, 02/02/2024 - 17:18 February 2, 2024 — GE HealthCare (Nasdaq: GEHC) announces the latest innovation in electrophysiology (EP), the Prucka 3 with CardioLab EP Recording system, to help clinicians in the diagnosis and treatment of cardiac arrhythmias. million people in the United States by 2050 and 17.9
By 1909 ECGs were being used to diagnose cases of arrhythmia; by 1910 to diagnose indicators of a heart attack. In April 2022 BMS had received FDA approval for Camzyos, the first drug developed specifically for targeting HCM. For example, in March 2023 Bristol Myers Squibb (BMS) partnered with Viz.ai How Has Funding Progressed?
Mitral valve prolapse (MVP)-associated sudden cardiac death may be the result of mechanical stress-induced fibrosis and substrate for ventricular arrhythmias. Europace (2022) 00, 1-10). We have recently shown that a surgical MVP model creates papillary muscle (PM) region fibrosis.
Massie Block -Ref 1) But, if there is something unusual in the clinical history, be ready to investigate until the arrhythmia, or at least the anxiety disappears. Clinical and electrophysiologic findings in patients with paroxysmal slowing of the sinus rate and apparent Mobitz type II atrioventricular block. 2022 Jan 5;11(1):279.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Patients undergoing first-time atrial fibrillation (AF) ablation can benefit from targeting non-pulmonary vein (PV) triggers. Preprocedural identification of high-risk individuals can guide planning of ablation strategy.
This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. Opinion is divided on the need for electrophysiology study. With proper precautions, risk can be reduced.
Methods and Results Patients with symptomatic, drug-resistant paroxysmal AF for first ablation were prospectively enrolled from September 2020 to January 2022. First-pass isolation, acute pulmonary vein (PV) reconnections, 1-year arrhythmia recurrence, and major complications were assessed. vs. 53.3%, p = .005). vs. 14.2%, p = .246).
Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
We aimed to investigate the prevalence of NSVT in patients with ATTRwr-CA, and the association of NSVT with sustained ventricular arrhythmias (VA) and all-cause mortality. Patients with NSVT have a higher risk of incident sustained VT compared to those without NSVT.
A subgroup of patients with MVP may experience ventricular arrhythmias and sudden cardiac death (“arrhythmic mitral valve prolapse” [AMVP]) but how to stratify arrhythmic risk is still unclear. Abstract Introduction Mitral valve prolapse (MVP) is a common clinical condition in the general population.
Published on November 30, 2023, in the Journal of the American College of Cardiology, these new guidelines are based on a comprehensive literature review from May 2022 to November 2022, and provide important recommendations to clinicians caring for patients with or at risk of developing cardiovascular disease (CVD).
Distinction is made between: ERP ( E arly R epolarization " P attern" ) in which the ECG findings of early repolarization are seen in the absence of symptomatic arrhythmias. ER associated with a rapidly ascending ( upsloping ) ST segments are the most common form and are also generally associated with low risk of malignant arrhythmias.
So, we are looking for signs of an underlying regular atrial rhythm ( with perhaps slight sinus arrhythmia ) — and it is much easier to find this when you know what you are looking for! ( See "Lesson #3" in My Comment at the bottom of the page of the April 2, 2022 post for more on the diagnostic value of fusion beats ).
He was discharged with an event monitor and electrophysiology follow up. He subsequently woke up on the ground, unsure how long he had been unconscious. He presented for evaluation where inpatient workup including monitoring on telemetry was unremarkable. What do you think? Figure-1: I've labeled today's continuous rhythm strip.
