چکیده

Electromyographic responses of the canine-pyeloureter to dobutamine, a beta 1-adrenoceptor agonist were investigated in vitro. Dobutamine produced a marked enhancement of potential in the pelvicalyceal (PC-) border, but failed to evoke noticeable responses in the renal pelvis and ureter. Dobutamine, however, made the pacemaker rhythm a little slow. This finding shows that the renal pacemaker is somewhat different form the cardiac pacemaker, pace of which is quickened by dobutamine.

Is correction for metallic artefacts mandatory in cardiac SPECT/CT imaging in the presence of pacemaker and implantable cardioverter defibrillator leads?

Introduction: Metallic artifacts due to pacemaker/ implantable cardioverter defibrillator (ICD) leads in CT images can produce artifactual uptake in cardiac SPECT/CT images. The aim of this study was to determine the influence of the metallic artifacts due to pacemaker and ICD leads on myocardial SPECT/CT imaging. Methods: The study included 9 patients wh...

Erosive Pressure Dermatitis Associated with Cardiac Pacemaker

Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...

Abstract: Background and Aim: Since electrocardiography (ECG) is essential for the diagnosis of pediatric asymptomatic Complete Heart Block (CHB) and it is not usually done in the preoperative evaluation of asymptomatic children, physicians might confront with asymptomatic cases of CHB at anesthesia induction. Case Report: In this study, we introduced a 31-month-old boy who faced CHB after anes...

The Improvement of the Atrial Flutter Rhythm upon the Removal of the Infected Permanent Pacemaker Lead

Pacemaker infection has multiple risk factors. Its presentation is most often similar to infected endocarditis and the diagnosis is made through studying blood cultures. Transesophageal echocardiography can confirm the diagnosis. The most common microorganisms are staphylococcus speciesis. As a matter of fact, complete pacemaker removal appears to be the only definite treatment. We presented a ...

Effect of Subchronic Administration of Aqueous Artemisia annua Extract on a1-Adrenoceptor Agonist-Induced Contraction of Isolated Aorta in Rat

Artemisia species, growing in almost all the northern hemisphere, is used in folk medicine of some countries as a remedy for hypertension. Since some cardiovascular disorders including hypertension are accompanied with altered responsiveness of vascular alpha-adrenergic receptors, the effect of aqueous Artemisia annua extract (100 and 200 mg kg-1) on a1-adrenoceptor agonist-induced contraction ...
