The effect of captopril on neurally evoked bradycardia and tachycardia was investigated in pithed rats. Captopril enhanced the vagal nerve stimulation-evoked bradycardia. Angiotensin I reduced the vagal bradycardia, which was reversed by subsequent administration of captopril. Bradykinin did not affect the neurally evoked bradycardia. Captopril and angiotensin I affected neither the exogenous a...

BACKGROUND In this study, we tested the hypothesis that 17beta-estradiol contributes to testosterone-mediated restoration of baroreflex-mediated bradycardia in short-term (3 weeks) castrated rats. Further, a reported increase in serum testosterone after long-term (6 weeks) castration constituted a basis for testing the hypothesis that a spontaneous increase in serum testosterone or androstenedi...

Background. Cesarean section is performed through an open abdominal incision (laparotomy) and the uterus (hysterotomy). Generally, cesarean with regional anesthesia techniques, spinal being primary choice. Complications that often occur after administration of include hypotension, bradycardia, postoperative nausea vomiting. The aim this study was thus to identify incidence vomiting caused by du...

BACKGROUND Previous studies have shown that testosterone enhances baroreflex bradycardia. Therefore, conscious unrestrained rats were used to investigate the role of the androgen receptor in the testosterone-mediated modulation of baroreflex bradycardia. Androgen depletion (3 weeks), and androgen receptor blockade (20-24 h), were implemented to test the hypothesis that testosterone influences b...

BACKGROUND AND PURPOSE Hypotension and bradycardia are common in carotid artery stenting (CAS) and are particularly worrisome in the high risk patient who is typically referred for CAS. The purpose of this work was to assess the incidence and predictors of hypotension and bradycardia and the risk of their delayed occurrence after CAS. MATERIALS AND METHODS A total of 53 men and 40 women (medi...

Background: Remdesivir has shown a positive impact on patient’s clinical improvement with COVID-19 and could represent future viral infections. Results: 16 out of 37 patients presented bradycardia, 4 these had QTc > 450 ms. Infusion for 3 days or more infusion higher incidence bradycardia (12 vs patients). Overall, without longer hospitalization (20.5 15.5 d...
