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 .
Drowning is a leading cause of unintentional injury and death worldwide, and the highest rates are among children. Overall, drowning is the most common fatal injury among children aged 1–4 years in the USA, [8] and is the second highest cause of death altogether in that age range, after congenital defects.
Bradycardia: The heart rate decreases significantly when the face is exposed to cold water. This helps to conserve oxygen by slowing down the heartbeat. The degree of bradycardia can vary among individuals, but it is a common and well-documented response.
Apnea of prematurity is a disorder in infants who are preterm that is defined as cessation of breathing that lasts for more than 20 seconds and/or is accompanied by hypoxia or bradycardia. Apnea of prematurity is often linked to earlier prematurity (younger gestational age).
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
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 ...
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]
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 ...
