Cushing reflex' is characterized by the occurrence of hypertension, bradycardia and apnoea secondary to raised increased intracranial pressure (ICP), leading to pressure on and or stretch, or both, of the brainstem. With the wide availability of monitoring facilities and advancements in investigation techniques, observation of increased intracranial ...

Diving Bradycardia and Withdrawal Bradycardia in Caiman crocodilus
Nature, 1969DIVING animals have been reported to respond with a drastic reduction in heart rate when their head is submerged; this is known as “diving bradycardia”. The phenomenon has been reported in dozens of species including some that do not ordinarily dive1. The bradycardia is extreme; for example, the heart rate of the alligator drops from 41 to 3 (ref.

The Journal of Sports Medicine, 1974
Heart rate response to apnea in air and water during rest and steady-state exercise was studied in 20 male college students Significant bradycardia (p < 0.05) due to apnea was observed at rest and during exercise A significant increase in bradycardia (P < 0 01 ) due to apneic face immersion in water was observed at rest and during exercise.

DMW - Deutsche Medizinische Wochenschrift, 2008
Repeated intake of 240-400 mg non-retard verapamil by a 26-year-old male nurse brought about interference dissociation resulting from extreme sinus bradycardia, passive AV nodal rhythm and hypotension. Because of a history of myocarditis a recurrence was suspected and an organic cause of the arrhythmia assumed at first, until its self-inflicted origin ...

Bradycardia and Pacemakers [PDF]
InnovAiT: Education and inspiration for general practice, 2012 Bradycardia has been defined historically as a heart rate below 60 beats/minute (bpm). However, many healthy individuals have a resting heart rate below this and some groups (such as endurance athletes) may have a resting heart rate of less than 30 bpm. For this reason, a strict lower limit is probably not useful and clinicians should use the presence

Progress in Pediatric Cardiology, 2000
Heart rate monitoring has become a ubiquitous part of fetal and neonatal assessment, and has made detection of bradycardia in the fetal and neonatal periods a frequent occurrence. Evaluation of a fetus or neonate with bradycardia requires an understanding of the mechanisms of bradycardia as well as the cardiac and non-cardiac causes of bradycardia. The

Acta Paediatrica, 2009
AbstractWe discuss the case of a newborn boy presenting well into term with severe bradycardic events and sinus pauses up to 5.4 sec. Sinus bradycardia below 80 bpm and sinus pauses or asystole of more than 2 sec are considered pathologic at term. After exclusion of specific causes, the diagnosis of vagal hyper‐reflectivity (VHR) was retained, a state ...

Bradycardia in a Man With Hypertension
The American Journal of Cardiology, 2019A man without cardiac symptoms was found to have a slow irregular pulse, and an electrocardiogram revealed sinus bradycardia with escape-capture bigeminy. He was taking verapamil, clonidine, and hydralazine for hypertension. The verapamil was discontinued; he returned to normal sinus rhythm and was discharged on the second hospital day.

Survey of Anesthesiology, 1978
ABSTRACTIn the aged, sinus bradycardia represents the sinus‐node‐dysfunction component of diffuse conduction system disease associated with coronary and cerebral arteriosclerosis. Findings are presented on 15 patients whose ages ranged from 69 to 93 years at the time of admission to a home for the aged.
