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)...

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...

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...

BACKGROUND: Previous studies have shown beneficial effects of levosimendan in high-risk patients undergoing cardiac surgery. Two large randomized controlled trials (RCTs), however, showed no advantages of levosimendan. METHODS: We performed a systematic review and meta-analysis (MEDLINE and Embase from inception until March 30, 2017), investigating whether levosimendan offers advantages compared with placebo in high-risk cardiac surgery patients, as defined by preoperative left ventricular ejection fraction (LVEF) ≤ 35% and/or low cardiac output syndrome (LCOS)...

In general practice palpitations are reported in around 8 per 1,000 persons per year. The differential diagnosis includes cardiac and psychiatric causes, as well as numerous others e.g. anaemia, hyperthyroidism, prescribed medication, caffeine and recreational drugs. Factors that point towards a cardiac aetiology are male sex, irregular heartbeat, history of heart disease, event duration > 5 minutes, frequent palpitations, and palpitations which occur at work or disturb sleep. Other clues suggesting a cardiac origin are abrupt onset and termination of palpitations, positional palpitations, and accompanying symptoms such as dizziness and presyncope...

INTRODUCTION: Commotion cordis and cardiac injuries are rare events usually following a chest blunt trauma during sports activities. EVIDENCE ACQUISITION AND SYNTHESIS: Various aetiologies have been identified to cause electrical (commotion cordis) and/or structural (contusion and further injuries) damage, but high-velocity tools such as baseballs or hockey pucks (also called projectiles) have been chiefly identified. Clinical consequences are challenging, varying from uncomplicated supraventricular arrhythmias to cardiac wall rupture...

INTRODUCTION: Stochastic damage of the ionizing radiation to both patients and medical staff is a drawback of fluoroscopic guidance during catheter ablation of cardiac arrhythmias. Therefore, emerging zero-fluoroscopy catheter-guidance techniques are of great interest. METHODS AND RESULTS: We investigated in a prospective pilot study the feasibility and safety of the cryothermal (CA) slow-pathway ablation in patients with symptomatic atrioventricular-nodal-reentry-tachycardia (AVNRT) using solely intracardiac echocardiography (ICE) for endovascular and endocardial catheter visualization...

Supraventricular tachyarrhythmia (SVT), especially atrial fibrillation (AF), has been observed in patients with inherited cardiac arrhythmia (ICA). Data on the time course of SVT and the occurrence of SVT other than AF is limited. In this study, we examined the prevalence, co-existence, and the time course of different types of SVT in patients with various ICAs. In this retrospective study, we selected 393 patients (median 49 years, range 17 to 87, 57% male) from a cohort of patients visiting the outpatient clinic for cardiogenetic screening of ICA...

BACKGROUND: Despite a lack of clear evidence, current European guidelines recommend antiplatelet therapy after transcatheter aortic valve replacement (TAVR). Recent investigations suggest that bioprosthesis thrombosis after TAVR is not uncommon and may be prevented by anticoagulation, but not by antiplatelet therapy. AIMS: The study objective was to assess the impact of the antithrombotic regimen on post-TAVR early haemodynamics. METHODS: Patients eligible for TAVR with an Edwards SAPIEN 3 valve were included in this prospective observational study...

Electrocardiographic artifacts are defined as electrocardiographic alterations, not related to cardiac electrical activity. As a result of artifacts, the components of the electrocardiogram (ECG) such as the baseline and waves can be distorted. Motion artifacts are due to shaking with rhythmic movement. Examples of motion artifacts include tremors with no evident cause, Parkinson's disease, cerebellar or intention tremor, anxiety, hyperthyroidism, multiple sclerosis, and drugs such as amphetamines, xanthines, lithium, benzodiazepines, or shivering (due to hypothermia, fever (rigor due to shaking), cardiopulmonary resuscitation by chest compression (oscillations of great amplitude) and patients who move their limbs during the test, causing sudden irregularities in the ECG baseline that may resemble premature contractions or interfere with ECG wave shapes, or other supraventricular and ventricular arrhythmias...
