Tachycardia-induced cardiomyopathy caused by ventricular tachycardia is a well-defined clinical entity. Less well appreciated whether simple ectopy can result in cardiomyopathy. We sought to examine potential causal relationship between repetitive monomorphic originating from the right outflow tract and role of ablation reversing this process.The study consisted 27 patients (11 men; age, 47+/-15 years) with ectopy, including 8 (30%) depressed function (ejection fraction < or =45%). All...
Coronavirus disease 2019 (COVID-19) is a global pandemic that wreaking havoc on the health and economy of much human civilization. Electrophysiologists have been impacted personally professionally by this catastrophe. In joint article from representatives Heart Rhythm Society, American College Cardiology, Association, we identify potential risks exposure to patients, allied healthcare staff, industry representatives, hospital administrators. We also describe impact COVID-19 cardiac...

Abstract Introduction The impact of atrial arrhythmias on coronavirus disease 2019 (COVID‐19)‐associated outcomes are unclear. We sought to identify prevalence, risk factors and associated with among patients hospitalized COVID‐19. Methods An observational cohort study 1053 severe acute respiratory syndrome 2 infection admitted a quaternary care hospital community was conducted. Data from electrocardiographic telemetry were collected fibrillation (AF) or flutter/tachycardia (AFL)....
Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used for patients with cardiogenic shock. Although Impella or intra-aortic balloon pump (IABP) frequently left ventricular unloading (LVU) during VA-ECMO treatment, there are limited data on comparative outcomes. We compared outcomes of and IABP LVU VA-ECMO.
Introduction: “Idiopathic” ventricular arrhythmias most often arise from the right outflow tract (RVOT), although left (LVOT) are also observed. While previous work has elucidated mechanism and electropharmacologic profile of RVOT arrhythmias, it is unclear whether those LVOT share these properties. The purpose this study was to characterize properties arrhythmias. Methods Results: One hundred twenty‐two consecutive patients (61 male; 50.9 ± 15.2 years) with comprise series, 100 (82%) an...
Idiopathic left ventricular arrhythmias (VAs) and those caused by structural heart disease can originate from the papillary muscles, fascicles, mitral annulus. Differentiation of these be challenging because they present with a right bundle branch block morphology electrocardiography. We sought to identify clinical, electrocardiographic, electrophysiological features that distinguish VAs in patients without disease.Patients undergoing catheter ablation for muscle, fascicular, or annular were...
Background Readmission after ST‐segment–elevation myocardial infarction ( STEMI ) poses an enormous economic burden to the US healthcare system. Efforts prevent readmissions should be based on understanding timing and causes of these readmissions. This study aimed investigate contemporary causes, timing, cost 30‐day . Methods Results All hospitalizations were selected in Nationwide Readmissions Database NRD from 2010 2014. The readmission rate as well primary cause examined. Multivariate...
Abstract Aims Although catheter ablation has emerged as an important therapy for patients with symptomatic atrial fibrillation (AF), there are limited data on sex-based differences in outcomes. We sought to compare in-hospital outcomes and 30-day readmissions of women men undergoing AF ablation. Methods results Using the United States Nationwide Readmissions Database, we analysed between 2010 2014. Based ICD-9-CM codes, identified co-morbidities Multivariable logistic regression inverse...
Background The independent prognostic value of troponin and other biomarker elevation among patients with coronavirus disease 2019 (COVID-19) are unclear. We sought to characterize levels in hospitalized COVID-19 develop validate a mortality risk score. Methods Results An observational cohort study 1053 was conducted. Patients all the following biomarkers measured-troponin-I, B-type natriuretic peptide, C-reactive protein, ferritin, d-dimer (n=446) -were identified. Maximum for each were...
Post-operative atrial fibrillation (POAF) is associated with stroke and mortality. It unknown if POAF subsequent heart failure (HF) hospitalization. This study aims to examine the association between incident HF hospitalization among patients undergoing cardiac non-cardiac surgeries.
Introduction: Pacemaker (PPM)‐detected atrial high‐rate episodes (AHREs) of even 5‐minute duration may identify patients at increased risk for stroke and death. In this study, we sought to determine the incidence newly detected fibrillation (AF defined as an AHRE ≥5 minutes) in following dual‐chamber PPM implantation define clinical predictors developing AF. Methods Results: We evaluated 262 (142 male; age 74 ± 12 years) without documented AF who underwent sinus node dysfunction (n = 122) or...
Idiopathic ventricular arrhythmias of left bundle branch block inferior axis morphology are usually localized to the right outflow tract (RVOT), presumably below pulmonic valve (PV). However, PV location is not confirmed by direct visualization.Intracardiac echocardiography was used visualize and tag annulus, which then integrated with 3-dimensional voltage maps RVOT. Distances were measured from furthest extent myocardial signal (bipolar ≥1.5 mV) annulus. This performed in 24 control...
Background and Purpose: One-fifth of ischemic strokes are embolic undetermined source (ESUS). Their theoretical causes can be classified as cardioembolic versus noncardioembolic. This distinction has important implications, but the categories’ proportions unknown. Methods: Using data from Cornell Acute Stroke Academic Registry, we trained a machine-learning algorithm to distinguish non-cardioembolic strokes, then applied ESUS cases determine predicted proportion with an occult source. A...
The PRAETORIAN trial (A Prospective, Randomized Comparison of Subcutaneous and Transvenous Implantable Cardioverter Defibrillator Therapy) showed noninferiority subcutaneous implantable cardioverter defibrillator (S-ICD) compared with transvenous (TV-ICD) regard to inappropriate shocks complications. In contrast TV-ICD, S-ICD cannot provide antitachycardia pacing for monomorphic ventricular tachycardia. This prespecified secondary analysis evaluates appropriate therapy whether reduces the...
