Role of Tissue-Doppler Imaging to Assess Left Ventricular Function in Patients with Right Ventricular Pacing
Tissue-doppler imaging Left ventricular function Right ventricular pacing
2015/9/18
Background: Right ventricular apical (RVA) pacing has been reported to impair diastolic and systolic function. These changes were usually studied by conventional echocardiography, while tissue-doppler...
Rate-Dependent Effects of Dofetilide on Epicardial Monophasic Action Potentials in Isolated Rabbit Heart with Atrial Pacing
Dofetilide Rate dependency Monophasic action potential duration Interventricular dispersion Langendorff perfusion
2009/6/25
Dofetilide (UK 68,798), a new antiarrhythmic agent, blocks potassium channels selectively and acts primarily by prolonging repolarization duration. The aim of this study was to investigate rate-depend...
Percutaneous Repositioning of dislodged atrial pacing lead
Atrial pacing lead Dislodgement Urologic basket Percutaneous repositioning
2010/4/6
The overall rate of atrial pacing lead dislodgement is estimated to be about 3%. These leads are generally repositioned via a second operation through opening the pacemaker pocket.
Some operators hav...
