PURPOSE: Paroxysmal supraventricular tachycardia (PSVT) ablation can result in injury to the atrioventricular (AV) node causing complete heart block requiring permanent pacemaker (PPM) implantation. Few studies have examined the impact of hospital PSVT ablation volume and PPM implantation rates post ablation. METHODS: We included adult patients from the Nationwide Inpatient Sample (NIS) database, from 1998 to 2011, using ICD-9 diagnoses codes 427.0 and 427.89 for PSVT and ICD-9 procedure code 37...

Cardiac disease is a common clinical manifestation present in a variety of neuromuscular disorders, most notably the muscular dystrophies. Heart disease may produce the presenting or predominant symptoms in these disorders but more often does not result in clinical features at the time of initial presentation. Cardiac involvement in the muscular dystrophies results from pathologic changes in the myocardium and the cardiac conduction system, leading to cardiomyopathy and/or rhythm disturbances including supraventricular arrhythmias, life-threatening ventricular arrhythmias, and sudden cardiac death...

BACKGROUND: Several studies suggested beneficial effects of perioperative levosimendan on postoperative outcome after cardiac surgery. However, three large randomized controlled trials (RCTs) have been recently published and presented neutral results. We performed a systematic review with meta-analysis and trial sequential analysis (TSA) to assess benefits and harms of perioperative levosimendan therapy in cardiac surgery. METHODS: Electronic databases were searched up to September 2017 for RCTs on preoperative levosimendan versus any type of control...

In this study, we investigated the correlation of air temperature, pressure and concentration of air pollutants with the rate of admissions for cardiac arrhythmias at two clinical centers in the area with a humid continental climate. This retrospective study included 3749 patients with arrhythmias admitted to emergency department (ED). They were classified into four groups: supraventricular tachycardia (SVT), ventricular tachycardia (VT), atrial fibrillation/undulation (Afib/Aund), and palpitations (with no ECG changes, or with sinus tachycardia and extrasystoles)...

Congenital cardiovascular anomalies, such as dextrocardia, persistent left superior vena cava (SVC), and pulmonary artery (PA) sling, are rare disorders. These congenital anomalies can occur alone, or coincide with other congenital malformations. In the majority of cases, congenital anomalies are detected early in life by certain signs and symptoms. A 56-year-old man with no previous medical history was admitted due to recurrent wide QRS complex tachycardia with hemodynamic collapse. A chest radiograph showed dextrocardia...

We developed a novel imaging technique, designated as vortex flow (VF) mapping, which presents a vortex flow visually on conventional two-dimensional (2D) cine MRI. Using it, we assessed circumferential VF patterns and influences on RA thrombus and supraventricular tachycardia (SVT) in AP connection-type Fontan circulation. Retrospectively, we enrolled 27 consecutive patients (25.1 ± 9.2 years) and 7 age-matched controls who underwent cardiac MRI. Conventional cine images acquired using a 1.5-Tesla scanner were scanned for axial and coronal cross section of the RA...

Unintentional poisonings are a global health problem frequently resulting in hospital admissions. Propafenone is a class 1C antiarrhythmic drug used in the second-line management of supraventricular and ventricular arrhythmias and, when unintentionally ingested, can lead to severe and life-threatening poisoning. We describe a case of a 3-year-old male patient unintentionally ingesting 300 mg (20 mg/kg) of propafenone and presenting with ventricular tachycardia with QT prolongation. Two boli of intravenous hypertonic sodium bicarbonate (total amount of 3 mEq/kg), followed by 3-hours continuous infusion of 1 mEq kg h sodium bicarbonate, were able to restore the clinical conditions of the patient...

Septic shock is a life-threatening condition that occurs when the blood pressure drops to a low level after an infection. Atrial fibrillation (AF) is the most common arrhythmia to complicate its course. Beta (β)-blockers are often administrated to manage supraventricular tachyarrhythmias observed in patients presenting with sepsis. A 74-year-old woman presenting with sepsis demonstrated AF tachycardia characterised by severe hypotension. She was refractory to conventional therapy including verapamil and digoxin; therefore, treatment using landiolol (an ultrashort-acting β-blocker) was initiated...

OBJECTIVE: To determine the association of pulmonary valve replacement (PVR) with death and sustained ventricular tachycardia (VT) in patients with repaired tetralogy of Fallot (rTOF). METHODS: Subjects with rTOF and cardiac magnetic resonance from an international registry were included. A PVR propensity score was created to adjust for baseline differences. PVR consensus criteria were predefined as pulmonary regurgitation >25% and ≥2 of the following criteria: right ventricular (RV) end-diastolic volume >160 mL/m(2), RV end-systolic volume >80 mL/m(2), RV ejection fraction (EF) <47%, left ventricular EF <55% and QRS duration >160 ms...

STUDY OBJECTIVE: Adenosine administration with a stopcock is the recommended treatment for pediatric patients with acute supraventricular tachycardia. Recent reports suggest that many infants do not respond to the first dose of adenosine administered. Our aim is to determine whether administration of adenosine with a stopcock delivers lower-than-expected drug doses in patients weighing less than 10 kg, corresponding to weights of infants. METHODS: We developed an in vitro model of adenosine delivery...

Ventricular arrhythmias include a wide range of potentially benign single ventricular premature contractions to ventricular tachycardia and ventricular fibrillation with a risk for sudden cardiac death. The diagnosis of ventricular arrhythmia is made by 12-lead electrocardiogram, 24 h Holter monitoring, an external or implantable loop recorder, or during in-hospital monitoring. Especially the diagnosis of wide complex tachycardias is challenging in terms of differentiating between ventricular tachycardia and supraventricular tachycardia with aberrant atrioventricular conduction...
