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 ...

The Evaluation and Management of Bradycardia
New England Journal of Medicine, 2000Bradycardia is a common finding during the clinical evaluation of both healthy patients and those who are ill. Bradycardia may be caused either by intrinsic dysfunction of or damage to the conduction system or by the response of normal tissues to extrinsic factors.

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.

Bradycardia as an early warning sign for cardiac arrest during routine laparoscopic surgery.
International Journal for Quality in Health Care, 2015OBJECTIVES The aim of this study was to identify clinical patterns of occurrence, management and outcomes surrounding cardiac arrest during laparoscopic surgery using the Australian Incident Monitoring Study (AIMS) database to guide possible prevention ...

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.

Training and bradycardia in rats
American Journal of Physiology-Legacy Content, 1965Bradycardia produced by training was investigated in 228 mature male rats belonging to normal, vagotomized, diencephalon-lesioned, immunological sympathectomized, and hypophysectomized groups. During a 70-day experimental period, resting heart rates of trained unanesthetized rats were significantly lower than those of non-trained rats at approximately
