BACKGROUND: Following ablation therapy for cardiac arrhythmias, patients may develop upper gastrointestinal (UGI) symptoms. The vagus nerve is close to the atria and may be affected by ablating energy. AIM: To identify structural or functional complications in UGI tract following ablation for atrial fibrillation (AF) and clinical outcomes and association with vagal dysfunction. METHODS: Using natural language processing of electronic medical records and an AF ablation database of 5380 patients treated during 17 years, we identified 40 patients with UGI complications...

OBJECTIVE: To evaluate the diagnostic potential of seven examinations in order to define the most suitable strategy for target organ damage (TOD) search in hypertensive patients. METHODS: This is a descriptive, cross-sectional study. 153 consecutive treated and essential hypertensive patients were enrolled. Patients with established cardiovascular or chronic renal disease (stage ≥4) were excluded. TOD search was assessed by: glomerular filtration rate (GFR), albumin/creatinine ratio (ACR), electrocardiogram (ECG), echocardiogram (ECO), ankle-brachial index (ABI), pulse wave velocity (PWV), and carotid ultrasound (intima media thickness and presence of plaques)...

Pharmacologic challenge with sodium channel blockers is part of the diagnostic workout in patients with suspected Brugada syndrome. The test is overall considered safe but both ajmaline and flecainide detain well known pro-arrhythmic properties. Moreover, the treatment of patients with life-threatening arrhythmias during these diagnostic procedures is not well defined. Current consensus guidelines suggest to adopt cautious protocols interrupting the sodium channel blockers as soon as any ECG alteration appears...

PURPOSE OF REVIEW: The present review offers an update on entities presenting as chest pain in the adolescent population. It discusses recently proposed tools and shared mental models used in primary and urgent care settings to evaluate chest pain, and their focus on identifying life-threatening processes. We consider whether the current practice may be improved by accounting for the increasingly recognized non-life-threatening causes of adolescent chest pain. RECENT FINDINGS: The present experiences and behaviors of adolescents have added new causes of chest pain to the work-up of this disquieting chief complaint...

Philosophy, merits and limitations of a novel method for wide QRS complex tachycardia differentiation, based on a scoring system and called the ventricular tachycardia (VT) score, were explained. The following criteria were assigned one point: initial dominant R wave in V1; initial r>40 ms in V1 or V2; notched S in V1; initial R wave in aVR; lead II RWPT≥50 ms; and absence of an RS in leads V1-V6. Atrioventricular dissociation (including fusion/capture beats and partial dissociation) was assigned two points...

STUDY OBJECTIVE: Current guidelines recommend patients presenting with transient ischemic attack (TIA) undergo echocardiography to evaluate for a cardiac source. However, echocardiography is not available daily at many centers. We assessed the yield from early transthoracic echocardiography (TTE) in consecutive patients with TIA evaluated in an emergency department observation unit (EDOU) protocol. METHODS: This observational cohort study took place in an academic medical center from January 1, 2011 to July 31, 2013...

BACKGROUND AND PURPOSE: Prolonged electrocardiogram (ECG) monitoring after ischaemic stroke increases the diagnostic yield of paroxysmal atrial fibrillation (pAF). In order to facilitate the additional workload involved in ECG analysis due to prolonged monitoring times, we investigated the effectiveness of pAF detection with an automated software algorithm (SA) in comparison to the routine staff-based analysis (RA) during standard stroke-unit care. Therefore, patients with acute ischaemic stroke or transitory ischaemic attack presenting with sinus rhythmus on the admission ECG and no history of atrial fibrillation were prospectively included...

OBJECTIVES: Guidelines recommend a 0h/1h high-sensitivity cardiac troponin T (hs-cTnT) diagnostic strategy in acute chest pain patients. There is however little data on the performance of this strategy when combined with clinical risk stratification. We aimed to evaluate the diagnostic accuracy of an accelerated diagnostic protocol (ADP) using the 0h/1h hs-cTnT strategy together with an adapted Thrombolysis In Myocardial Infarction (TIMI) score and ECG for ruling out major adverse cardiac events (MACE) within 30 days...

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

OBJECTIVES: To define clinical correlates of low voltage isolated to precordial leads on the surface electrocardiogram (ECG). INTRODUCTION: Low voltage (V) on the ECG is defined as QRS V<5mm in all limb leads and <10mm in all precordial leads. The diagnostic use of ECGs with low voltage isolated to the precordial leads with normal limb lead voltages is unclear. METHODS: Twelve-lead ECGs with QRS V>5mm in one or more limb leads and <10mm in all precordial leads were collected...

OBJECTIVE: Heart failure is a major cause of disease burden in sub-Saharan Africa (SSA). There is an urgent need for better strategies for heart failure management in this region. However, there is little information on the capacity to diagnose and treat heart failure in SSA. We aim to provide a better understanding of the capacity to diagnose and treat heart failure in Kenya and Uganda to inform policy planning and interventions. METHODS: We analysed data from a nationally representative survey of health facilities in Kenya and Uganda (197 health facilities in Uganda and 143 in Kenya)...

AIMS: This study independently evaluated the diagnostic performance of electrocardiographic (ECG) criteria to predict the infarct related artery (IRA) in patients with an acute ST-segment elevation myocardial infarction (STEMI). While a number of ECG criteria have been proposed to predict the IRA in STEMI, many of these "rules" came from modestly sized populations and did not undergo external validation. Therefore, we evaluated popular criteria from the literature in an independent cohort...

Ventricular tachyarrhythmias include potentially lethal episodes of sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) as well as hemodynamically tolerated ventricular ectopic activity. Sustained VT or VF may develop in the setting of acute myocardial infarction or as clinical sequelae of advanced cardiomyopathy. The incidence of these serious arrhythmias is estimated from retrospective and observational studies and registries of sudden cardiac arrest and sudden cardiac death. Over the past few decades, there has been a gradual decline in the incidence of life-threatening ventricular tachyarrhythmias which has been largely driven by upstream treatments for and prevention of coronary artery disease and its sequelae...

Vertigo and dizziness are among the most common chief complaints in the emergency department. Etiologies can be categorized into three subgroups: neurootological (vestibular), medical (especially cardiovascular, metabolic), and psychiatric disorders. The diagnostic approach in the emergency department is based on a systematic analysis of case history (type, time course of symptoms, modulating factors, associated symptoms), clinical examination of the vestibular, ocular motor, and cerebellar systems (head impulse test, nystagmus, skew deviation, positioning maneuver, test of gait and stance), as well as a basal monitoring (vital signs, 12-lead ECG, blood tests)...

A large number of ST-elevation notifications are generated by cardiac monitoring systems, but only a fraction of them is related to the critical condition known as ST-segment elevation myocardial infarction (STEMI) in which the blockage of coronary artery causes ST-segment elevation. Confounders such as acute pericarditis and benign early repolarization create electrocardiographic patterns mimicking STEMI but usually do not benefit from a real-time notification. A STEMI screening algorithm able to recognize those confounders utilizing capabilities of diagnostic ECG algorithms in variation analysis of ST segments helps to avoid triggering a non-actionable ST-elevation notification...
