BACKGROUND AND PURPOSE: Cardioembolic stroke accounts for approximately 15%-20% of all ischemic strokes. Atrial fibrillation constitutes one-half to two-thirds of all cardioembolic stroke events. The association of paroxysmal supraventricular tachycardia (PSVT) with ischemic stroke remains unclear. A national case-control study was conducted to identify the risk factors, including PSVT, for ischemic stroke in Taiwan. METHODS: We designed a national case-control study comprising patients diagnosed with ischemic stroke (n = 5633) from 1997 to 2011; each patient from the case group was randomly matched with the control group (n = 30,895) in Taiwan...

BACKGROUND: Portal and/or splenic vein thrombosis (PSVT) is common after splenectomy. It can be a life-threatening complication, with a risk of bowel ischemia and portal hypertension. An early diagnosis allows an effective medical treatment and prevents life-threatening complications. There is no consensus regarding the benefit of systematic screening of patients after splenectomy for PSVT. We started in January 2012 a routine screening of PSVT after elective splenectomy. The aim of this study was to assess this policy...

Cardiac lymphoma is extremely rare. An intracardiac mass has rarely been reported to be the cardiac involvement of extranodal lymphoma. It is difficult to establish a final diagnosis via routine examinations. The ability of an echocardiogram to characterize tissue is limited; systemic (18)F-FDG PET/CT scans provide important information for both staging and response assessment in patients with lymphoma. A 68-year-old Chinese male with a second patent foramen ovale (PFO) and an interventricular septal defect presented at our institute with persistent fever, shortness of breath, repeated paroxysmal supraventricular tachycardia (PSVT) attack, and rapidly progressing superior vena cava syndrome...

Spatial intelligence is often linked to success in engineering education and engineering professions. The use of electroencephalography enables comparative calculation of individuals' neural efficiency as they perform successive tasks requiring spatial ability to derive solutions. Neural efficiency here is defined as having less beta activation, and therefore expending fewer neural resources, to perform a task in comparison to other groups or other tasks. For inter-task comparisons of tasks with similar durations, these measurements may enable a comparison of task type difficulty...

REVIEW
Salah S Al-Zaiti, Kathy S Magdic
Paroxysmal supraventricular tachycardia (PSVT) is a well-known and thoroughly studied clinical syndrome, characterized by regular tachycardia rhythm with sudden onset and abrupt termination. Most patients present with palpitations and dizziness, and their electrocardiogram demonstrates a narrow QRS complex and regular tachycardia with hidden or inverted P waves. PSVT is caused by re-entry due to the presence of inhomogeneous, accessory, or concealed conducting pathways. Hemodynamically stable patients are treated by vagal maneuvers, intravenous adenosine, diltiazem, or verapamil, hemodynamically unstable patients are treated by cardioversion...

BACKGROUND: Slow pathway modification (SPM) is the therapy of choice for AV-nodal reentry tachycardia (AVNRT). When AVNRT is not inducible, empirical ablation can be considered, however, the outcome in patients with two AV nodal echo beats (AVNEBs) is unknown. METHODS: Out of a population of 3003 patients who underwent slow pathway modification at our institution between 1993 and 2013, we retrospectively included 32 patients with a history of symptomatic tachycardia, lack of paroxysmal supraventricular tachycardia (pSVT) inducibility but occurrence of two AVNEBs...

Adenosine can produce arrhythmias, which are generally short living. It may induce PACs and PVCs, sinus bradycardia, and atrial fibrillation. There have been reports of transient polymorphic VT (torsades de pointes) in patients with LQTS and others in people with normal QT interval. We report a case of a long episode of polymorphic VT induced by adenosine. A 27 year old woman received 6 mg adenosine for PSVT, which terminated and torsades de pointes developed, persisting for 17 seconds and terminated spontaneously...

Atrial natriuretic peptide (ANP) secretion increases after 30 min of paroxysmal supraventricular tachycardia (PSVT). Whether this phenomenon also applies to brain or C-type natriuretic peptides (BNP or CNP) remains unknown. Blood samples of 18 patients (41 ± 11 yr old; 4 men) with symptomatic PSVT and normal left ventricular systolic function (ejection fraction 65 ± 6%) were collected from the coronary sinus (CS) and the femoral artery (FA) before and 30 min after the induction, and 30 min after the termination of PSVT...

We experienced a rare case of anterior mediastinal bronchogenic cyst. A 55-year-old female was admitted to our hospital because of paroxysmal supraventricular tachycardia (PSVT) and an abnormal shadow on the chest computed tomography. She had a 5.5 cm tumor at anterior mediastinum. The tumor was surgically removed completely by video assisted thoracoscopic surgery, and the diagnosis of bronchogenic cyst was established pathologically. After surgery, PSVT has disappeared.

BACKGROUND: Portal and/or splenic vein thrombosis (PSVT) is a potentially lethal complication of splenectomy for hematologic disease. Known risk factors for PSVT include malignancy and splenomegaly. While these patients are believed to be hypercoagulable, the specific mechanism is unclear. The aim of this study is to evaluate whether specific acquired prothrombotic risk factors contribute to the development of PSVT following laparoscopic splenectomy (LS). METHODS: Consecutive patients undergoing LS were prospectively studied between 2005 and 2013...
