Objective: Patients with electrical injury are considered to be at high risk of cardiac arrhythmias. Due to the small number of studies, there is no widely accepted guideline regarding the risk assessment and management of arrhythmic complications after electrical accident (EA). Our retrospective observational study was designed to determine the prevalence of ECG abnormalities and cardiac arrhythmias after EA, to evaluate the predictive value of cardiac biomarkers for this condition and to assess in-hospital and 30-day mortality.

We present the case of a 14-year-old female patient with recurrent episodes of paroxysmal supraventricular tachycardia (PSVT). Her ECG showed a PR interval of 160 ms in lead II, and a delta wave pattern in leads V2 and V3, with a normal QRS interval of 100 ms. We analyzed the three criteria for confirmation of minimal pre-excitation: (i) absence of a Q wave in V6; (ii) presence of an R wave in V1 and (iii) absence of an R wave in avR. Read More

Introduction: Fluoroscopy use during catheter ablation procedures increases the cumulative lifetime radiation exposure of patients and operators, potentially leading to a higher risk of cancer and radiation-related injuries. Nonfluoroscopic ablation (NFA) has been described for supraventricular tachycardia, typical atrial flutter, paroxysmal atrial fibrillation (AF), and outflow-tract ventricular tachycardia (VT). Complete transition to NFA of more complex arrhythmias, including persistent AF, left atrial (LA) flutter, and structural VT, has not been previously described. Read More

Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of reentrant paroxysmal supraventricular tachycardia that occurs in the presence of dual AV nodal physiology. Wolff-Parkinson-White (WPW) syndrome is another type of supraventricular tachycardia characterized by short PR intervals, delta waves and wide QRS complexes on the surface electrocardiogram (ECG), reflecting atrioventricular pre-excitation. Uncommonly, AV nodal reentry and accessory pathways can coexist. Read More

The atrioventricular (AV) node is an anatomically well-defined structure, conveniently housed in the triangle of Koch. There are two distinct atrial impulse approaches to the AV node, one of which (in the anterior portion of triangle of Koch) has a faster conduction, while the other one (in the posterior portion) has a slower conduction. However, it is not said that such a conductive duality translates into any arrhythmic phenomena. Read More

Atrioventricular nodal reentry tachycardia (AVNRT) is the most common form of regular paroxysmal supraventricular tachycardia. This arrhythmia affects women twice as frequently as men, and is often diagnosed in patients <40 years of age. Familial clustering, early onset of symptoms and lack of structural anomaly indicate involvement of genetic factors in AVNRT pathophysiology. Read More

We studied the predictors and patterns of high-sensitivity cardiac troponin T (hs-cTnT) elevation in patients with paroxysmal supraventricular tachycardia (PSVT) in the presence and absence of ischemic heart disease. During calendar year 2013, we enrolled 70 of 72 consecutive adult patients with PSVT who presented at our center within 4 hours after the onset of tachycardia. On the basis of increased hs-cTnT at either of 2 initial measurements, we divided patients into groups (hs-cTnT-positive and hs-cTnT-negative), to study the predictors of enzyme elevation. Read More
