"Cardioversion" AND "Emergency"

OBJECTIVE: Direct current electrical cardioversion (DCCV) is an effective rhythm-control option for patients with atrial fibrillation (AF). Despite initial success, a high recurrence rate remains a significant challenge. There is limited data on the genetic predictors of AF recurrence following successful DCCV. In this study, we aimed to evaluate whether 11 single nucleotide polymorphisms (SNPs) previously associated with AF are also linked to recurrence after DCCV in the Turkish population...

Drug-induced long QT syndrome (LQTS) is defined as prolonged corrected QT interval (QTc ≥460 ms) plus polymorphic ventricular arrhythmia fitting the description of torsades de pointes temporally associated with the administration of a drug or combination of drugs. Amiodarone therapy is a known uncommon cause of acquired QT interval prolongation that should not be underestimated. We present a case of an iatrogenic electrical storm with atrial fibrillation (AF) in which amiodarone was administered to attempt chemical cardioversion, resulting in an unnoticed prolongation of the QT interval, with subsequent repeated polymorphic ventricular tachycardia, managed with isoproterenol...

BACKGROUND/AIM: Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with the functional impairment of multiple joints and the destruction of bone and cartilage. Methotrexate (MTX) is a first-line drug commonly used to treat RA; however, even low doses of MTX can potentially cause rare but severe adverse reactions, such as neutropenic enterocolitis (NE), a life-threatening disease characterized by intestinal mucosal damage and immunodeficiency. CASE REPORT: Here, we report on an 82-year-old RA patient who developed life-threatening NE after ten years of low-dose MTX treatment...

Atrial fibrillation (AF) and acute heart failure (AHF) are two closely interrelated conditions that frequently coexist in a manifold manner, with AF serving either as the causative factor or as the consequence or even as an innocent bystander. The interplay between these two clinical conditions is complex, given that they share common pathophysiological pathways and they can reciprocally exacerbate each other, thus triggering a vicious cycle that worsens the prognosis and increases the thromboembolic risk. The optimal management of AF in the context of AHF in the emergency department remains a challenge depending on the time onset, as well as the nature and the severity of the associated symptoms...

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 mg twice daily or placebo for 10 days. The first dose of the study drug was administered within 4 hours before ablation. Atrial arrhythmia recurrence was defined as AF, atrial flutter, or atrial tachycardia >30 s on two 14-day Holters performed immediately and at 3 months following ablation...

QUESTION: Recently, a 3-year-old patient in my practice urgently needed to go to the emergency department. The patient was found to have supraventricular tachycardia (SVT) and needed immediate treatment with adenosine. What evidence is currently available for management of SVT in children? ANSWER: Supraventricular tachycardia is a common cardiac condition in the pediatric population that manifests as a narrow QRS complex tachycardia on electrocardiography. Symptoms may range from palpitations, poor feeding, and irritability to more substantial hemodynamic instability...

INTRODUCTION: Fulminant myocarditis is a devastating disease with significant mortality and complications. The care of patients with fulminant myocarditis is rarely reported. CLINICAL FINDINGS: A 17-year-old female patient was admitted to the emergency department with dizziness, amaurosis fugax, and chest tightness. Initial assessment revealed elevated levels of troponin T (4.753 ng/mL), troponin I (49.540 ng/mL), creatine kinase (1306 U/L), creatine kinase-MB isoenzymes (75...

INTRODUCTION: Electrical cardioversion for atrial fibrillation/atrial flutter (AF/AFL) is common in the ED. Our previous work showed that hypotension and respiratory events were important adverse events that occurred in patients undergoing electrical cardioversion for AF/AFL. The purpose of this study was to examine if (1) beta-blockers or calcium channel blocker use prior to ECV were associated with hypotension and (2) medications used for procedural sedation were associated with respiratory events...

OBJECTIVE: The aim was to explore the association of demographic and prehospital parameters with short-term and long-term mortality in acute life-threatening cardiovascular disease by using a hazard model, focusing on elderly individuals, by comparing patients under 75 years versus patients over 75 years of age. DESIGN: Prospective, multicentre, observational study. SETTING: Emergency medical services (EMS) delivery study gathering data from two back-to-back studies between 1 October 2019 and 30 November 2021...

OBJECTIVE: To compare outcomes of patients presenting to emergency medical services (EMS) with atrial fibrillation with rapid ventricular response (AF-RVR) who did and did not receive prehospital advanced life support (ALS) rate or rhythm control intervention(s). METHODS: This retrospective cohort study used the 2021 ESO Data Collaborative (Austin, TX) dataset. We identified 9-1-1 scene responses for patients aged 16 to 100 years old presenting with AF and an initial heart rate ≥ 110 beats per minute (bpm)...

AUDIENCE: This scenario was developed to educate emergency medicine residents on the diagnosis and management of ventricular tachycardia (VT) that is refractory to single dose anti-arrhythmic management. BACKGROUND: Electrical storm, defined as three or more episodes of sustained VT, ventricular fibrillation, or appropriate shocks from an implantable cardioverter defibrillator within 24 hours,1 has a mortality rate up to 14% in the first 48 hours.2 Ventricular tachycardia may present in a heterogenous fashion, not only with stable versus unstable clinical presentations, but also with different electrocardiographic morphologies and etiologies...

Plant exposures leading to systemic or topical toxicity are common presentations seen in the emergency department. While often nonfatal, certain highly toxic plants result in cardiovascular or respiratory failure requiring invasive management. We describe a 65-y-old patient who presented with a refractory ventricular dysrhythmia secondary to an unintentional ingestion of an aconitine-containing plant after incorrect identification. Despite aggressive treatment with vasopressors, intravenous fluids, antiarrhythmics, as well as electrolyte correction and multiple attempted synchronized cardioversions, the patient remained in a refractory dysrhythmia with cardiogenic shock...

BACKGROUND: There are limited data on gender-based differences in atrial fibrillation (AF) treatment and prognosis. We aimed to examine gender-related differences in medical attention in an emergency department (ED) and follow-up (FU) among patients diagnosed with an AF episode and to determine whether there are gender-related differences in clinical characteristics, therapeutic strategies, and long-term adverse events in this population. METHODS: We performed a retrospective observational study of patients who presented to a tertiary hospital ER for AF from 2010 to 2015, with a minimum FU of one year...

BACKGROUND: Stem cell transplantation is an emerging therapy for severe cardiomyopathy, proffering stem cell recruitment, anti-apoptosis, and proangiogenic capabilities. Angiogenic cell precursors (ACP-01) are autologous, lineage-specific, cells derived from a multipotent progenitor cell population, with strong potential to effectively engraft, form blood vessels, and support tissue survival and regeneration. METHODS: This IRB approved outcome analysis reports upon 74 consecutive patients who failed medical management for severe cardiomyopathy, and were selected to undergo transcatheter intramyocardial or intracoronary implantation of ACP-01...

BACKGROUND: There are multiple reported injuries associated with cardiopulmonary resuscitation, most of them caused by the force of compressions, like sternal and rib fractures, abdominal organ injuries like splenic rupture, liver lacerations, and injuries to the upper airway and skin. Injuries related to defibrillation and cardioversion are rare, mostly related to skin and muscle injuries on where the defibrillation paddles were placed. CASE REPORT: A 52-year-old man presented to the Emergency Department with crushing chest pain...

BACKGROUND: In the Rate Control versus Electrical Cardioversion Trial 7-Acute Cardioversion versus Wait and See, patients with recent-onset atrial fibrillation (AF) were randomized to either early or delayed cardioversion. AIM: This prespecified sub-analysis aimed to evaluate heart rate during AF recurrences after an emergency department (ED) visit identified by an electrocardiogram (ECG)-based handheld device. METHODS: After the ED visit, included patients (n = 437) were asked to use an ECG-based handheld device to monitor for recurrences during the 4-week follow-up period...

Catheter ablation has become an important treatment strategy for the management of atrial fibrillation (AF) in symptomatic patients. Pulmonary vein isolation (PVI) is increasingly used to restore rhythm in patients with AF and flutter. The serious procedural complication rate has significantly reduced over time and most patients undergo PVI without any adverse events. We present the case of a 70-year-old man with symptomatic AF who underwent elective PVI that was complicated by large pericardial effusion from left atrial appendage (LAA) perforation resulting in cardiac tamponade requiring emergency pericardiocentesis followed by sternotomy to suture the LAA...

BACKGROUND: Palpitations represent a common cause for consultation in the pediatric Emergency Department (ED). Unlike adults, palpitations in children are less frequently dependent from the heart, recognizing other causes. CASE PRESENTATION: A 11-year-old male came to our pediatric ED for epigastric pain, vomiting and palpitations. During the previous 6 month the patient was affected by SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus). Electrocardiogram (ECG) revealed supraventricular tachycardia...

Atrial fibrillation (AF) is the most prevalent sustained arrhythmia managed in emergency departments, and the already high prevalence of this arrhythmia is increasing in Spain. This serious condition associated with increased mortality and morbidity has a negative impact on patient quality of life and the functioning of the health care system. The management of AF requires consideration of diverse clinical variables and a large number of possible therapeutic approaches, justifying action plans to coordinate the work of several medical specialties in the interest of providing appropriate care and optimizing resources...

Introduction: Hospitalizations during the coronavirus 2019 (COVID-19) pandemic peaked in New York in March-April 2020. In the months following, emergency department (ED) volumes declined. Our objective in this study was to examine the effect of this decline on the procedural experience of emergency medicine (EM) residents compared to the pre-pandemic period. Methods: We conducted this multicenter, retrospective cohort study of patients seen and key procedures performed by EM residents at hospitals spanning three Accreditation Committee for Graduate Medical Education-approved EM residencies in New York City and Nassau County, NY...
