Sinus corticosteroids-induced bradycardia with high dose steroids has been reported in literature. Although the association is still not clearly understood but several mechanisms have been prompted to explain causality. The authors had a case of 54 years female who presented with slurred speech and confusion that was noted while she was at work. In the emergency department the patient was hypot...

Purpose. To report the resolution of bradycardia encountered during transradial cardiac catheterization through the catheter pullback technique in two cases. Case Report. A 62-year-old male and an 81-year-old male underwent coronary angiogram to evaluate for coronary artery disease and as a result of positive stress test, respectively. Upon engagement of the FL 3.5 catheter into the ascending a...

I report a case of hypotension and bradycardia before spinal anesthesia in a pregnant woman with mild to moderate hypertension treated with nifedipine and methyldopa, scheduled for an elective cesarean delivery. She had the history of neurally-mediated syncopes. Two main factors (increased vagal tone and adverse effects of antihypertensive drugs) could explain the hypotension and bradycardia be...

The process of micturition is related to activation of the cardiovascular autonomic nervous system. Hypotension with bradycardia often occurs during or immediately after micturition. We experienced a case of sudden severe hypotension and bradycardia following urethral catheterization in a patient who underwent an urethral dilatation and transurethral resection of bladder tumor while under gener...

TO THE EDITOR: Boyett et al. (1) provides interesting evidences, arguing that endurance training-induced bradycardia seems mostly related to a remodeling of the sinoatrial node. However, we would like to add four complementary elements to extend this paper. About intrinsic heart rate. In Boyett et al.’s Table 1, seven studies explored long-time endurance athletes and three studies explored subj...

Spinal anesthesia has been regarded as safe and simple technique since its introduction into anesthesia practice. Bradycardia and hypotension under spinal anesthesia is a known phenomenon. However sudden unexpected bradycardia and cardiac arrest under spinal anesthesia is considered as rare and uncommon manifestation. On the contrary, as per current reviews, severe bradycardia and cardiac arres...

To the Editor—I read with interest the article by Chuang et al.1 The authors do not mention bradycardia as an important finding in dengue fever. Heart rate, as well as body temperature, is routinely recorded in all febrile patients. Lateef et al2 report that relative bradycardia (pulse temperature deficit) should raise awareness of such an infection. While this feature may be noted in other inf...

A hypermagnesemic adult sheep during an experimental study showed gastraointestinal and respiratory changes along with cardiovascular alterations included of obvious bradycardia and heart block. In order to save the animal from fatal bradycardia, atropine sulfate was administrated instatntly at one dose 0.3 mg/kg. The animal was survived and rhythm returned to sinus rhythm from marked bradycard...

OBJECTIVE To evaluate the effect of stochastic resonance (SR) stimulation on preterm infant oxygen desaturation, bradycardia, and apnea events. We hypothesized that SR stimulation will reduce these events. METHODS This was a randomized crossover study conducted from April 2012 to July 2014. Eligible preterm infants were not receiving ventilation support and had at least 1 clinically documente...

Steroids are used for specific indications in the perioperative period to reduce laryngeal or spinal cord edema, or for prophylaxis and treatment of postoperative nausea and vomiting. Given the other potential causes for hemodynamic alterations in the perioperative setting, it is important for physicians to be aware of cardiovascular side effects of short term steroids. Changes in blood pressur...
