Disease relevance of Tachycardia, Supraventricular

• BACKGROUND: Adenosine is considered safe and effective for paroxysmal supraventricular tachycardia (PSVT), but anecdotal experience suggests that adenosine can precipitate atrial arrhythmias [1].
• BACKGROUND: Recent reports suggest that adenosine, in addition to terminating supraventricular tachycardia involving the atrioventricular (AV) node, may have antiarrhythmic effects on atrial tachycardia [2].
• Prevention of symptomatic recurrences of paroxysmal atrial fibrillation in patients initially tolerating antiarrhythmic therapy. A multicenter, double-blind, crossover study of flecainide and placebo with transtelephonic monitoring. Flecainide Supraventricular Tachycardia Study Group [3].
• Nongastrointestinal toxicity of this thiotepa/pentoxifylline combination was infrequent and included bone marrow depression and supraventricular tachycardia [4].
• A 31 year old woman who developed an atypical ventricular tachycardia after administration of intravenous verapamil for control of a recurrent supraventricular tachycardia is presented [5].

High impact information on Tachycardia, Supraventricular

• Adenosine and supraventricular tachycardia [6].
• We suggest that patients with congestive cardiomyopathy be carefully screened for supraventricular tachycardia [7].
• Atenolol appeared to reduce significantly the likelihood of supraventricular tachycardia and ST-segment and T-wave changes and prevented cardiac necrosis seen at necropsy [8].
• Atrial natriuretic peptide in paroxysmal supraventricular tachycardia [9].
• Persistent supraventricular tachycardia treated with mexiletine [10].

Chemical compound and disease context of Tachycardia, Supraventricular

• Oral verapamil for paroxysmal supraventricular tachycardia: a long-term, double-blind randomized trial [11].
• Termination of supraventricular tachycardia occurred in 15 of the 20 patients receiving propafenone but 0 of the 11 patients receiving placebo (p less than 0.01) [12].
• Oral flecainide acetate was administered to 34 patients with documented symptomatic paroxysmal supraventricular tachycardia (PSVT) with a double-blind, placebo-controlled, 8-week crossover trial design [13].
• The purpose of this study was to determine if the known frequency-dependent effects of diltiazem on inward calcium current result in selective actions during supraventricular tachycardia [14].
• Termination of paroxysmal supraventricular tachycardia with a single oral dose of diltiazem and propranolol [15].

Biological context of Tachycardia, Supraventricular

• For paroxysmal supraventricular tachycardia initiated in the electrophysiology laboratory, it is concluded that intravenous diltiazem is safe and very effective for acute tachycardia termination when the AV node is part of the reentrant circuit [16].
• Amiodarone was used for recurrent supraventricular tachycardia in four cases and frequent ventricular extra systoles complicating congenital QT prolongation in the remaining case [17].
• AIMS: To analyse whether heart rate may affect the efficacy of adenosine, verapamil and carotid sinus massage in terminating symptomatic episodes of paroxysmal supraventricular tachycardia (PSVT) in adults [18].
• Flecainide prolonged action potential refractoriness in a few patients in each group; however, an increased frequency of occurrence of paroxysmal supraventricular tachycardia occurred due to a simultaneous decrease in the re-entry circuit conduction velocity [19].
• CONCLUSION: Digoxin might be used safely and successfully to treat fetal supraventricular tachycardia in multifetal pregnancies [20].

Anatomical context of Tachycardia, Supraventricular

• BACKGROUND: Adenosine administered intravenously terminates supraventricular tachycardias (SVT) involving the AV node as part of the reentrant circuit [21].
• Electrophysiological studies utilizing His bundle recordings and atrial extra-stimulus technique were performed in 17 patients (pts) with documented paroxysmal supraventricular tachycardia (PSVT) before and after 0.01 mg/kg, i.v., ouabain [22].
• However, 40 micrograms/ml of protamine caused a more pronounced decline in myocyte function and beta-adrenergic responsiveness in the supraventricular tachycardia group [23].
• Efficacy of nadolol in preventing supraventricular tachycardia after coronary artery bypass grafting [24].
• A 31-year-old man with incomplete T11 paraplegia on the basis of spinal cord ischemia developed supraventricular tachycardia 37 days after surgery to repair an aortic tear [25].

Gene context of Tachycardia, Supraventricular

• The heart temperature was kept at 10 degrees to 15 degrees C. Patients were evaluated intraoperatively and postoperatively for (1) supraventricular tachycardia, (2) ECG changes, (3) lactate dehydrogenase and total CPK and isoenzyme (MB) studies, and (4) hemodynamic studies in the intensive care unit [26].
• Electrophysiologic studies were performed in 28 patients with documented atrioventricular (AV) nodal reentrant supraventricular tachycardia (SVT) to investigate the presence of AV nodal tissue situated between the tachycardia circuit and both the atrium (upper common pathway, UCP) and the His bundle (lower common pathway, LCP) [27].
• Premature atrial and/or ventricular contractions were found in 55 per cent, premature ventricular contractions in 45 per cent, supraventricular tachycardia in 6.1 per cent and ventricular tachycardia in 6.3 per cent [28].
• The hemodynamic effects of supraventricular tachycardia in ventricular septal defect with pulmonary outflow tract obstruction [29].
• The effectiveness of somatostatin to interrupt paroxysmal supraventricular tachycardias was assessed in 18 patients [30].

Analytical, diagnostic and therapeutic context of Tachycardia, Supraventricular
