Long-term ECG is widely used in diagnosis and assessment of many cardiac symptoms which may be caused by dangerous arrhythmias that sometimes can be difficult to document. The PocketECG system is a new technological solution for a long-term, noninvasive, continuous and real-time ECG monitoring that provides automatic diagnosis of dysrhythmias. ECG data transmission occurs over a mobile network. The goal of this study was to assess the reliability of long-term ECG recordings acquired with the PocketECG system...

Background: A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease...

BACKGROUND: Persistent tachycardia in pediatric patients after congenital heart surgery further deteriorates their hemodynamic condition, and may become fatal. Therefore, immediate control of the tachycardia is mandatory in these patients. For this purpose, quick-acting, short-acting, titratable intravenous agents are required. However, there are no agents with such characteristics among the drugs approved for control of pediatric arrhythmias in Japan, and thus novel and effective medications for these patients are awaited...

BACKGROUND: Increased cardiac troponin concentrations in acute coronary syndrome (ACS) identify patients with ongoing cardiomyocyte necrosis who are at increased risk. However, with the use of more precise assays, cardiac troponin increases are commonly noted in other cardiovascular conditions as well. This has generated interest in the use of cardiac troponin for prognostic assessment and clinical management of these patients. In this review, we have summarized the data from studies investigating the implications of cardiac troponin concentrations in various acute and chronic conditions beyond ACS, i...

BACKGROUND: Guidelines recommend that implantable loop recorders (ILRs) are used in the evaluation of people with recurrent unexplained syncope in the absence of high-risk criteria, and in high-risk patients after a negative evaluation. The aim of this systematic review was to analyze the diagnostic yield of ILRs in these patients. METHODS: We performed a systematic search in order to retrieve studies enrolling adults undergoing ILR implantation for undetermined syncope...

Supraventricular tachycardia is a common arrhythmia faced by emergency physicians in the pediatric population. In most cases, antecubital intravenous access can be established, and adenosine can be administered in a rapid and timely fashion. The role and administration of intraosseous adenosine are poorly established. We describe a case where the administration of adenosine was successful via a mixed method administration.

Regular narrow QRS tachycardia, particularly if well-tolerated, is usually considered a "benign" arrhythmia of a supraventricular origin. This case concerns an 82-year-old male with ischemic heart disease who presented with recurrent episodes of a narrow QRS tachycardia that was initially diagnosed and treated as atrial tachyarrhythmia. However, careful physical examination and ECG analysis established the correct diagnosis, and the patient was managed appropriately. Remarkably, the observation of irregular cannon A waves, and Lewis lead recording, confirmed atrioventricular dissociation during tachycardia and indicated its underlying mechanism...

INTRODUCTION: Supraventricular tachycardia (SVT) is the most common arrhythmia in the neonatal period, but its association with other triggering processes is not well established. The aim of the study was to analyse the possible relationship between neonatal SVT and gastroesophageal reflux disease (GERD), a condition which was recently linked to atrial arrhythmias. MATERIAL AND METHODS: A retrospective longitudinal descriptive study was conducted over a period of 5years on newborns who were diagnosed with SVT in a level III neonatal unit, assessing morphological aspects, associated symptoms, and treatments received...

BACKGROUND: Neutrophil/lymphocyte ratio (NLR) and red cell distribution width (RDW) may be associated with the onset of arrhythmias in adults, thus underlining a possible inflammatory etiology. Paroxysmal supraventricular tachycardia (SVT) is the most frequent pathological tachycardia in childhood. AIMS: To verify NLR and RDW levels in a group of children (<1 year) affected by SVT with a structurally normal heart and without fever nor inflammatory diseases; to compare NLR and RDW before and after SVT resolution, to verify whether the latter was related with the reduction in inflammatory state; to identify -in SVT subtypes caused by a re-entry mechanism- an NLR and RDW cut-off point beyond which adenosine was ineffective in preventing SVT recurrence...

Supraventricular tachycardia (SVT) is a common infant arrhythmia, for which beta-blockers are frequently chosen as therapy. Propranolol is a common choice though it is dosed every 6-8 h. We reviewed the clinical results of treating infant SVT with an extemporaneous preparation of nadolol. Retrospective cohort study of patients under 2 years old receiving nadolol for SVT at a single center. Patients were ascertained by patient and pharmacy databases. Twenty-eight infants received nadolol, of whom 25 had regular narrow complex tachycardia, 2 atrial flutter, and 1 focal atrial tachycardia...

Supraventricular tachycardia is the most common significant arrhythmia in children. If prolonged, it may cause heart failure and progress to cardiogenic shock warranting prompt treatment. The recommended interventions following vagal manoeuvres are intravenous adenosine and in the unstable patient electrical cardioversion. We present an infant with an unstable supraventricular tachycardia that was resistant to electrical cardioversion and recommended doses of adenosine. He reverted to sinus rhythm with a higher dose of adenosine, suggesting that such doses may be required in refractory supraventricular tachycardia...

Left atrial aneurysm is an extremely rare anomaly, which can be associated with supraventricular arrhythmia, compression of coronary arteries, intracardiac thrombus, life-threatening systemic embolization, pulmonary venous obstruction, mitral valve insufficiency, and congestive heart failure. Herein, we report a four-year-old boy who had a giant aneurysm of the left atrium and severe mitral regurgitation. The aneurysm and mitral valve cleft causing severe mitral regurgitation were successfully repaired.

OBJECTIVES: The study objective was to determine the predictors of new-onset arrhythmia among infants with single-ventricle anomalies during the post-Norwood hospitalization and the association of those arrhythmias with postoperative outcomes (ventilator time and length of stay) and interstage mortality. METHODS: After excluding patients with preoperative arrhythmias, we used data from the Pediatric Heart Network Single Ventricle Reconstruction Trial to identify risk factors for tachyarrhythmias (atrial fibrillation, atrial flutter, supraventricular tachycardia, junctional ectopic tachycardia, and ventricular tachycardia) and atrioventricular block (second or third degree) among 544 eligible patients...

AIMS: Non-fluoroscopic catheter ablation is becoming routine. In experienced centres, fluoroscopy is rarely required. The use of a traditional catheterization lab (cath lab) may no longer be necessary. We began performing catheter ablations at a paediatric centre outside the traditional cardiac cath lab in 2013. The purpose of this study was to compare procedural features of paediatric catheter ablation performed outside the cath lab to those performed within a cath lab. METHODS AND RESULTS: We prospectively looked at patients presenting to the paediatric centre with supraventricular tachycardia (SVT) undergoing catheter ablation outside the cath lab in a standard operating room (OR group)...

BACKGROUND: The nosological nature of "idiopathic" arrhythmias and the effect of etiotropic and pathogenetic treatment are often unknown. METHODS AND RESULTS: 19 patients (42.6±11.3 years, 9 women) with atrial fibrillation (n = 16), supraventricular (n = 10) and ventricular (n = 4) premature beats, supraventricular (n = 2) and ventricular tachycardia (n = 1), left bundle branch block (n= 2), AV block (n = 2) without structural heart changes. Viruses were identified (polymerase chain reaction, PCR) along with measurement of anti-heart antibodies (AHA) and endomyocardial biopsy (EMB)...

The term tachycardiomyopathy refers to a specific form of tachycardia-related cardiomyopathy caused by supraventricular or ventricular tachyarrhytmias that are both associated with ventricular rates higher than 120 bpm. The arrhythmias which are most frequently associated with these forms of heart disease are atrial fibrillation and atrial flutter, particularly found in the elderly population. The most frequent clinical manifestation is heart failure. In this case we are reporting a clinical case of a patient that came to our attention because of an episode of heart failure associated with atrial fibrillation and atrial flutter...
