tachycardia guidelines

BACKGROUND: Complications arising during non-operative management (NOM) of blunt hepatic and/or splenic trauma, particularly in cases of severe injury, are associated with significant morbidity and mortality. Abdominal computed tomography (CT) is the gold standard for the initial detection of complications during NOM. Although many institutions advocate routine in-hospital follow-up scans to improve success rates, others recommend a more selective approach. The use of follow-up CT remains a subject of ongoing debate, with no validated guidelines available regarding the timing, effectiveness, or intervals of follow-up imaging...

BACKGROUND: In many cardiac diseases, myocardial scar tissue detected by late gadolinium enhancement (LGE) is a risk factor for cardiac arrhythmia and sudden cardiac death. Previous studies in athletes reported an increased risk for cardiac events in this group of ostensibly healthy subjects. However, the currently available longitudinal studies on this topic included fairly old marathon runners with a mean age of 57 ± 6 years or represent a case-control study in athletes with preexisting ventricular arrhythmia...

This review summarizes current knowledge on post-acute sequelae of COVID-19 (PASC) and post-COVID-19 condition (PCC) in children and adolescents. A literature review was performed to synthesize information from clinical studies, expert opinions, and guidelines. PASC also termed Long COVID - at any age comprise a plethora of unspecific symptoms present later than 4 weeks after confirmed or probable infection with severe respiratory syndrome corona virus type 2 (SARS-CoV-2), without another medical explanation...

BACKGROUND: Sudden cardiac death (SCD) can be the first clinical event of Chagas heart disease (CHD). However, current guidelines contain no clear recommendation for early cardioverter-defibrillator implantation. Using imaging modalities, we evaluated associations among autonomic denervation, myocardial hypoperfusion, fibrosis and ventricular arrhythmia in CHD. METHODS AND RESULTS: Twenty-nine patients with CHD and preserved left ventricular function underwent 123I-metaiodobenzylguanidine (MIBG) scintigraphy, 99mTc-methoxyisobutylisonitrile (MIBI) myocardial perfusion and cardiac magnetic resonance imaging (MRI)...

A 66-year-old female was found hypotensive in ventricular tachycardia (V-tach). Workup confirmed septic shock and takotsubo cardiomyopathy (TCM) with left ventricular (LV) thrombus. Despite the initiation of anticoagulation therapy, she developed an embolic stroke on day 14. Malignant ventricular arrhythmia and LV thrombosis are rare complications of TCM. However, there is no specific guideline regarding prophylactic anticoagulation.

BACKGROUND AND OBJECTIVES: Despite the evidence that no other antipsychotic is effective as clozapine for the treatment of resistant schizophrenia, it is associated with various metabolic, neuroendocrine, cardiovascular, and gastrointestinal adverse effects. Guidelines aiming to address the monitoring of clozapine's (serious) adverse effects can be helpful to prevent and treat these effects. However, many of these guidelines seem to lack one or more important monitoring recommendations...

OBJECTIVES: The authors analyzed anesthetic management trends during ventricular tachycardia (VT) ablation, hypothesizing that (1) monitored anesthesia care (MAC) is more commonly used than general anesthesia (GA); (2) MAC uses significantly increased after release of the 2019 Expert Consensus Statement on Catheter Ablation of Ventricular Arrhythmias; and (3) anesthetic approach varies based on patient and hospital characteristics. DESIGN: Retrospective study. SETTING: National Anesthesia Clinical Outcomes Registry data...

PURPOSE OF REVIEW: Arrhythmias are common in patients with heart failure (HF) and are associated with a significant risk of mortality and morbidity. Optimal antiarrhythmic treatment is therefore essential. Here, we review current approaches to antiarrhythmic treatment in patients with HF. RECENT FINDINGS: In atrial fibrillation, rhythm control and ventricular rate control are accepted therapeutic strategies. In recent years, clinical trials have demonstrated a prognostic benefit of early rhythm control strategies and AF catheter ablation, especially in patients with HF with reduced ejection fraction...

BACKGROUND: Providing adequate paralysis and appropriate sedation is challenging in patients with obesity during rapid sequence intubation (RSI). Pharmacokinetic parameters play an important role in dosing of rocuronium due to low lipophilicity. Rocuronium may be dosed based on ideal body weight (IBW). Current guidelines do not offer recommendations for dosing in the setting of obesity. Dosing depends on clinician preference based on total body weight (TBW) or IBW. OBJECTIVE: In this study we performed non-inferiority analysis to compare the intubation conditions, duration of paralysis, and incidence of new-onset tachycardia or hypertension after intubation in obese patients requiring RSI in the emergency department (ED)...

BACKGROUND: Tachycardia-mediated cardiomyopathy (TMC) is a reversible form of heart failure with reduced ejection fraction (HFrEF), most commonly caused by atrial fibrillation or atrial flutter. Evidence for its management is scarce, and practice patterns are highly variable. OBJECTIVE: To describe management patterns for HFrEF and atrial arrhythmias in patients with TMC at a specialty heart failure clinic. METHODS: This retrospective cohort study involved adults with HFrEF and a physician-determined diagnosis of TMC, with an initial visit for this problem between October 2018 and October 2019...

Background and study aims Because of concerns about peri-procedural adverse events (AEs), guidelines recommend anesthetist-managed sedation (AMS) for long and complex endoscopic procedures. The safety and efficacy of physician-administered balanced sedation (PA-BS) for endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCPs) ≥20 mm is unknown. Patients and methods We compared PA-BS with AMS in a retrospective study of prospectively collected data from consecutive patients referred for management of LNPCPs (NCT01368289; NCT02000141)...

BACKGROUND: There is an association between coronavirus disease 2019 (COVID-19) mRNA vaccination and the incidence or exacerbation of postural orthostatic tachycardia syndrome (POTS). OBJECTIVE: The purpose of this study was to characterize patients reporting new or exacerbated POTS after receiving the mRNA COVID-19 vaccine. METHODS: We prospectively collected data from sequential patients in a POTS clinic between July 2021 and June 2022 reporting new or exacerbated POTS symptoms after COVID-19 vaccination...

Electrophysiological and interventional procedures have been increasingly used to reduce morbidity and mortality in patients experiencing cardiovascular diseases. Although antithrombotic therapies are critical to reduce the risk of stroke or other thromboembolic events, they can nonetheless increase the bleeding hazard. This is even more true in an aging population undergoing cardiac procedures in which the combination of oral anticoagulants and antiplatelet therapies would further increase the hemorrhagic risk...

Sickle cell disease (SCD) is a common genetic disorder associated with complications such as cholelithiasis. Cholecystectomy is often performed in SCD patients, but they have a higher risk of postoperative complications. Blood transfusion, while beneficial, can also have adverse effects. The optimal approach to perioperative transfusion in SCD patients is still debated. This case report presents a rare surgical presentation of gallbladder stones in an SCD patient complicated by a hemolysis crisis and bleeding after laparoscopic cholecystectomy...

INTRODUCTION: Pulmonary embolism (PE) is a prevalent condition with a substantial morbi-mortality worldwide. Proper risk stratification of PE is essential for identifying the most suitable therapeutic strategy and the optimal care setting for the patient. This process entails evaluating various factors, including symptoms, comorbidities, and right heart dysfunction. AREAS COVERED: This review assesses the tools and methods utilized to identify and stratify individuals based on the probability of developing deterioration or death related to PE...

We present a case of a 67-year-old male with heart failure with reduced ejection fraction due to a previous myocardial infarction, slow-conducting atrial fibrillation with an indication of pacemaker implantation, and sustained ventricular tachycardia, requiring defibrillation support in prevention of sudden cardiac death. Current guidelines recommend biventricular over conventional right ventricular pacing for patients with ejection fraction <40 % and atrioventricular conduction disorders in either sinus rhythm or atrial fibrillation, but in patients with a narrow baseline QRS complex, biventricular pacing still induces a form of electrical dyssynchrony...

Tachycardia-induced cardiomyopathy (TIC) is defined as a reversible left ventricular (LV) systolic dysfunction resulting from a sustained fast heart rate. LV remodeling in patients with severe LV dysfunction at diagnosis remains poorly understood. In this retrospective cohort study, we described LV remodeling in 50 patients who underwent atrial flutter ablation. These patients were divided into severe LV systolic dysfunction (SeD) (LVEF≤30%) and non-severe LV systolic dysfunction (NSeD) (LVEF 31-50%) at baseline...

Psoriasis is a chronic inflammatory cutaneous disease, affecting up to 3% of the worldwide population. Several clinical phenotypes can be distinguished. Among these, erythrodermic psoriasis (EP) is a rare and severe variant (less than 3% of cases), characterized by severe generalized erythema and scaling affecting at least 90% of the body surface area. EP is often a life-threatening condition, since several systemic symptoms (tachycardia, fever, fatigue, lymphadenopathy, dehydration, serum electrolyte disturbances) can be associated...

A review of the literature was made to find and choose research papers, on drugs (amiodarone and adenosine) used for managing supraventricular tachycardia (SVT) in children and infants (one hour to 17 years of age) with no structural heart disease by PRISMA guideline. Our team conducted an exhaustive systematic literature review (SLR), utilizing an extensive search methodology across recognized databases like PubMed, PubMed Central, Google Scholar, Web of Science, and The Cochrane Library. We included 10 scholarly articles that satisfied our rigorous selection criteria including systematic reviews/meta-analysis, and randomized control trials, shedding light on treatment with amiodarone and adenosine for SVT in pediatric patients...

BACKGROUND: Risks of radiofrequency catheter ablation for ventricular arrhythmias include emboli and bleeding complications but data on antithrombotic regimens are limited and guidelines do not specify a systematic approach. OBJECTIVES: This study sought to assess embolic and bleeding complications in relation to pre- and post-periprocedure antithrombotic regimens. METHODS: Prospective assessment for complications was performed for 663 endocardial radiofrequency catheter ablation procedures in 616 consecutive patients (median age 64 years [Q1-Q3: 54-73 years], 70...
