BACKGROUND AND AIMS: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common form of paroxysmal supraventricular tachycardia (SVT) whose diagnosis can be strongly suspected based on the surface eletrocardiogram alone. The purpose of this study is to determine the diagnostic accuracy of several electrocardiographic (ECG) criteria for the prediction of AVNRT. METHODS: Between November 2010 and January 2014, a total of 256 patients who underwent electrophysiological testing (EP) with regular, paroxysmal and narrow QRS complex tachycardia were prospectively enrolled...

BACKGROUND: Splanchnic venous thrombosis (SVT) is a relatively rare but important complication of necrotizing acute pancreatitis (NAP). Clinical manifestations and severity of this complication in different patients vary greatly, ranging from mild abdominal discomfort even asymptomatic to lethal gastrorrhagia or hepatic failure. The aim of the present study was to develop a model to predict the clinical manifestations of SVT in NAP patients. METHODS: This retrospective cohort study was conducted in the surgical intensive care unit (SICU) of Jinling Hospital...

INTRODUCTION: Approximately 10-20% of ICD recipients receive inappropriate device therapies. The purpose of this study was to compare the frequency of inappropriate therapies (IT) between men and women enrolled in MADIT II and MADIT-CRT, and assess for potential adverse outcomes. METHODS: The electrograms for each ICD or CRT-D therapy, defined as either ATP or shock, were reviewed by adjudication committees for both studies. ICD therapy was considered inappropriate if it was delivered for reasons other than VT/VF...

Breath analysis of rats using multi-capillary column ion-mobility spectrometry (MCC-IMS) revealed alterations in acetone and other ketones, including 3-pentanone, during inflammation. The alterations seem likely to result from oxidative branched-chain keto acid (BCKA) catabolism. We therefore tested the hypothesis that 3-pentanone arises during inflammation from increased BCKA oxidation in the liver with consequent accumulation of propionyl-CoA and its condensation products. Male Sprague-Dawley rats were anaesthetised and ventilated for 24 h or until death...

Ensuring sensing and detection of ventricular tachycardia (VT) and ventricular fibrillation (VF) was a prerequisite for the clinical trials that established the survival benefit of implantable cardioverter defibrillators (ICDs). However, for decades, a high incidence of unnecessary shocks limited patients' and physicians' acceptance of ICD therapy. Oversensing, misclassification of supraventricular tachycardia (SVT) as VT, and self-terminating VT accounted for the vast majority of unnecessary shocks. Medtronic ICDs utilize sensitive baseline settings with minimal blanking periods to ensure accurate sensing of VF, VT, and SVT electrograms...

Text recognition in video/natural scene images has gained significant attention in the field of image processing in many computer vision applications, which is much more challenging than recognition in plain background images. In this paper, we aim to restore complete character contours in video/scene images from gray values, in contrast to the conventional techniques that consider edge images/binary information as inputs for text detection and recognition. We explore and utilize the strengths of zero crossing points given by the Laplacian to identify stroke candidate pixels (SPC)...

INTRODUCTION: Supraventricular tachycardias (SVTs) are a common cause of acute hospital presentations. Adenosine is an effective treatment. To date, no studies have directly compared paramedic-with hospital-delivered treatment of acute SVT with adenosine. METHOD: Randomised controlled trial comparing the treatment of SVT and discharge by paramedics with conventional emergency department (ED)-based care. Patients were excluded if they had structural heart disease or contraindication to adenosine...

A 35-year-old female was referred with progressive dyspnoea and elevated heart rate. Surface electrocardiography (ECG) showed supraventricular tachycardia (SVT) with long RP interval and inverse P waves. ECG revealed left ventricular dilation and severe systolic dysfunction. An electrophysiological (EP) examination was performed due to incessant SVT despite betablocker medication. Permanent junctional reciprocating tachycardia (PJRT) was diagnosed and successfully ablated. During follow-up, the patient's symptoms abated and ECG parameters normalized...

: Essentials Pediatric studies on peripherally inserted central catheter (PICC)-related thrombosis are scarce. This study analyzes incidence and risk factors for PICC-related venous thrombosis in children. PICC-related thrombosis is a common, and nearly always, asymptomatic complication. Echo-guided insertion and a catheter to vein ratio < 0.33 may notably decrease this complication. SUMMARY: Background Upper-extremity venous thrombosis is associated with the use of peripherally inserted central catheters (PICCs)...

Pancreatic cancer is known for vague symptoms that lead to a delay in diagnosis, and hence most cases are found at an advanced stage. Many complications can happen secondary to pancreatic cancer including diabetes, malabsorption, and deep venous thrombosis. Sinistral (segmental or left-sided) portal hypertension (SPH) refers to portal hypertension confined to the left-sided segment of the portal venous system namely the splenic side, and the most common etiology is splenic vein thrombosis (SVT). We present here a case of a 66-year-old male with advanced pancreatic cancer who died due to bleeding secondary to SVT...

BACKGROUND: The optimal treatment for fetal supraventricular tachycardia (SVT) with 1:1 atrioventricular relationship is unclear. OBJECTIVE: We compared the effectiveness of transplacental treatment protocols used in 2 centers. METHODS: Pharmacologic treatment was used in 84 fetuses. Maternal oral flecainide was the primary therapy in center 1 (n = 34) and intravenous maternal digoxin in center 2 (n = 50). SVT mechanism was classified by mechanical ventriculoatrial (VA) time intervals as short VA or long VA...

BACKGROUND: Cardiac arrhythmias can occur during pregnancy. Owing to radiation exposure and other uncertain risks for the mother and fetus, catheter ablation has rarely been performed and is often delayed until the postpartum period. We reported 2 pregnant women who were experiencing severe arrhythmias and were successfully ablated without fluoroscopic guidance. We also carried out a literature review of cases of pregnant women who underwent zero-fluoroscopy ablation. METHODS AND RESULTS: One woman had drug-resistant and poorly tolerated frequent premature ventricular contraction (PVC) and ventricular tachycardia (VT)...

Arrhythmias are one of the most common forms of cardiac disease presenting in pregnancy. Women with underlying arrhythmias may only present to health care professionals when they are pregnant. The most common type of sustained arrhythmia presenting in pregnancy is a supraventricular tachycardia (SVT). This can be difficult to diagnose, as symptoms such as palpitations, dizziness and shortness of breath are also common symptoms of pregnancy. We present the management of a woman who developed intrapartum SVT...

PURPOSE: To evaluate the outcomes of transjugular intrahepatic portosystemic shunt (TIPS) for flow-enabled clearance of portal (PVT), splenic (SVT) and/or superior mesenteric (MVT) vein thrombosis. PATIENTS AND METHODS: In this single-center study, 12 patients underwent TIPS using Viatorr covered stent-grafts (W.L. Gore & Associates, Flagstaff, AZ, USA) from 2008-2014 for PVT as a primary (n=8) or secondary (n=4) indication. TIPS were not accompanied by pharmacomechanical clot disruption; rather, shunts served to increase portal blood flow to allow flow-mediated physiologic clot dissolution...
