We report a case of paroxysmal supraventricular tachycardia complicating Tako-Tsubo cardiomyopathy. We hypothesize that increased adrenergic tone supposedly underlying transient apical ballooning syndrome may facilitate the onset of paroxysmal supraventricular tachycardias in predisposed patients.

To improve long-term outcome after cryoablation of substrates of supraventricular tachycardia, application of two and three consecutive freeze-thaw cycles has been performed. The effect of triple freeze-thaw cycles on lesion formation within developing myocardium and coronary arteries, however, has not been studied yet. In eight piglets (mean age 15 weeks, weight 15-20 kg), 30 cryolesions (three consecutive freeze-thaw cycles) were applied to the atrial aspect of both AV valve annuli (n = 18) as well as to ventricular myocardium below the valves (n = 12)...

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: The outcomes related to chest pain associated with cocaine use and its burden on healthcare system are not well studied. METHODS: Data were collected from the Nationwide Inpatient Sample (2001 - 2012). Subjects were identified by using the ICD-9-CM codes. Primary outcome was a composite of mortality, myocardial infarction, stroke and cardiac arrest. RESULTS: We identified 363,143 admissions for cocaine induced chest pain. Mean age was 44...

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...

CASE DESCRIPTION 4 dogs were examined because of pleural effusion and ventricular tachycardia, coughing and supraventricular tachycardia, appendicular osteosarcoma, and syncopal episodes. CLINICAL FINDINGS In all 4 dogs, a heart base tumor was identified by means of thoracic CT. TREATMENT AND OUTCOME In all 4 dogs, the heart base tumors were treated by means of stereotactic body radiation therapy. Dogs were anesthetized, and neuromuscular blockade was achieved with atracurium or vecuronium. A circle rebreathing system with 15 m (50 feet) of anesthetic tubing coursing through the vault wall was used to connect the patient to the anesthesia machine, which was located in the control room...

Supraventricular arrhythmias are one of the main causes of medical consultation. They may also be the clinical presentation of various cardiovascular diseases and a marker of sudden death. The correct diagnosis of these arrhythmias could be a challenge. The purpose of this narrative review is to update succinctly on the topic.

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.

A 50-year-old male patient who had undergone Senning repair for transposition of the great arteries at the age of 7 years was referred to our electrophysiology lab with recurrent supraventricular tachycardias. Fast anatomical mapping of the systemic venous atrium was performed with the CARTO electroanatomical mapping system. Propagation mapping with animated dynamic maps facilitates the understanding of the underlying mechanism and provides visualization of reentrant circuits of tachycardias in cardiac chambers with native barriers and surgical scars...

CONTEXT: Olympic athletes represent model of success in our society, by enduring strenuous conditioning programmes and achieving astonishing performances. They also raise scientific and clinical interest, with regard to medical care and prevalence of cardiovascular (CV) abnormalities. OBJECTIVE: Our aim was to assess the prevalence and type of CV abnormalities in this selected athlete's cohort. DESIGN, SETTING AND PARTICIPANTS: 2352 Olympic athletes, mean age 25±6, 64% men, competing in 31 summer or 15 winter sports, were examined with history, physical examination, 12-lead and exercise ECG and echocardiography...

BACKGROUND: Treatment times for primary percutaneous coronary intervention frequently exceed the recommended maximum delay. Automated "physicianless" systems of prehospital cardiac catheterization laboratory (CCL) activation show promise, but have been met with resistance over concerns regarding the potential for false positive and inappropriate activations (IAs). METHODS: From 2010 to 2015, first responders performed electrocardiograms (ECGs) in the field for all patients with a complaint of chest pain or dyspnea...

AIMS: Early identification of patients who could benefit from early re-intervention after catheter ablation is highly warranted. Our aim was to investigate the association between post-procedural burden of supraventricular ectopic complexes (SVEC) and the risk of long-term atrial fibrillation (AF) recurrence. METHODS AND RESULTS: A total of 125 patients undergoing catheter ablation for AF were included. Patients underwent 7-day Holter recordings immediately post-procedural...

Definition of the most important factors and their combination, causing the disturbances of heart rhythm in patients with the pulmonary tuberculosis and diabetes, now attracts more and more attention. For this purpose, extensively used the capabilities of multifactorial analysis, which allowed to evaluate the distribution of the pathological factors and their interaction with each other. The objects of the study were complex examination the data of 90 patients with pulmonary tuberculosis and diabetes (insulin-dependent diabetes-27, non-insulin- dependent diabetes-63)...

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...

OBJECTIVES: We aimed to compare early postoperative outcome after extracardiac (EC) Fontan operation between patients with right (RV) or left (LV) systemic ventricles. METHODS: In total, 173 consecutive patients (median age 4 years, median weight 14 kg) underwent EC Fontan between 1995 and 2013. Pre- and intraoperative data as well as detailed postoperative haemodynamic variables were compared between patients with LV [n = 109 (63%)] and RV [n = 64 (37%)]...

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...
