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 .
Infant swimming is the phenomenon of human babies and toddlers reflexively moving themselves through water and changing their rate of respiration and heart rate in response to being submerged. The slowing of heart rate and breathing is called the bradycardic response. [ 1 ]
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]
Over 50% of infants who are born preterm are estimated to be affected by apnea of prematurity. [2] Infants who are born weighing less than 1000g have close to a 100% risk of being affected by apnea of prematurity. Most premature infants are affected by 'central' apnea due to the developmental stage of their respiratory tract. [2]
Anatomy and physiology is different in infants and children than adults and vary with age, which produces normal ranges for electrocardiograms. [26] Capillary refill is used across the lifespan as a cardiovascular assessment parameter because it is a non-invasive, quick test to help determine blood flow to the tissues.
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 ...
The child had recently completed treatment at Shriners Children’s Philadelphia hospital for a condition not easily treated in Mexico, hospital officials said. Her mother and four crew members ...
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 ...
