Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
Cardiac arrhythmias are another possible cause. Arrhythmias such as asystole or bradycardia are more likely in children, in contrast to ventricular fibrillation or tachycardia as seen in adults. [30] Additional causes of sudden unexplained cardiac arrest in children include hypertrophic cardiomyopathy and coronary artery abnormalities. [161]
A Centers for Disease Control and Prevention study in 2012 of United States data from 2005 to 2009 indicated that each year an average of 513 children aged 0–4 years were victims of fatal drowning and a further 3,057 of that age range were treated in U.S. hospital emergency departments for non-fatal drowning. Of all the age groups, children ...
increased or decreased fetal heart rate (tachycardia and bradycardia), especially during and after a contraction; decreased variability in the fetal heart rate; late decelerations; Biochemical signs, assessed by collecting a small sample of baby's blood from a scalp prick through the open cervix in labor fetal metabolic acidosis
Bradycardia is usually the first symptom of CHB to be detected in utero. [1] [5] [6] Due to the block in the atrioventricular node, less electric signals move from the sinoatrial node to the bundle of his and its right and left branches, leading to a lower heart rate. The atrioventricular block can be first degree or much more severe like a ...
Most premature infants are affected by 'central' apnea due to the developmental stage of their respiratory tract. [2] Apnea of prematurity can increase the risk of chronic health conditions including retinopathy and increases the risk of problems with the infant's neurological development. Apnea lasting more than 60 seconds may result in death ...
What makes it fatal is the damage to the brain and the nervous system from lack of sleep. Their brains can't recharge and, therefore, can't function normally. #7
It occurs when the infant has pauses in breathing for no more than 10 seconds at a time followed by a series of rapid, shallow breaths. Then the breathing returns to normal without any stimulation or intervention. These pauses in breathing may be accompanied by minor oxygen desaturation and bradycardia. It usually occurs when the infant is ...
