Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates.
Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachycardia); it is classified as a type of supraventricular tachycardia (SVT).
Left atrial appendage occlusion (LAAO), also referred to as left atrial appendage closure (LAAC), is a procedure used to reduce the risk of blood clots from the left atrial appendage entering the bloodstream and causing a stroke in those with non-valvular atrial fibrillation.
Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
The failure of the circulatory system of the newborn to adapt to these changes by lowering PVR leads to persistent fetal circulation. [2] The newborn is therefore born with elevated PVR, which leads to pulmonary hypertension. Because of this, the condition is also widely known as persistent pulmonary hypertension of the newborn (PPHN). [3]
Catheter ablation was considered to be a first-line treatment method for many people with typical atrial flutter due to its high rate of success (>90%) and low incidence of complications, [1] although pulsed field ablation now offers a non-thermal option. This is done in the cardiac electrophysiology lab by causing a ridge of scar tissue in the ...
There are no symptoms or signs associated with it. It was originally thought of as having a benign prognosis. In the Framingham Heart Study , however, the presence of a prolonged PR interval or first degree AV block doubled the risk of developing atrial fibrillation , tripled the risk of requiring an artificial pacemaker , and was associated ...
Newborn receiving positive pressure ventilation. Instead of referring to "fetal distress", current recommendations hold to look for more specific signs and symptoms, assess them, and take the appropriate steps to remedy the situation [1] through the implementation of intrauterine resuscitation. [13]
