When a congenital heart concern exists, doctors may perform open heart surgery to repair the heart or at least alleviate some of the risks. As your child grows, they’ll need to replace the pacemaker. The tip of the catheter is fitted with a device that can destroy the atypical tissue using radiofrequency energy or by freezing it (cryoablation).įor heart block, a surgeon may need to implant a pacemaker to keep the heart’s electrical activity steady. This is when a doctor threads a catheter through to the heart. In some cases, they may be enough to eliminate the arrhythmia permanently.Ī procedure called ablation can sometimes eliminate the cause of an irregular heartbeat.įor some structurally caused arrhythmias, such as Wolff-Parkinson-White syndrome, catheter ablation may be helpful. A 2022 study suggests that antiarrhythmic medications are often a safe and effective treatment for SVT in infants. The right treatment for neonatal arrhythmia depends on the type of arrhythmia and your baby’s age and overall health.Īntiarrhythmic medications are often first-line treatments for certain arrhythmias. What is the treatment for neonatal arrhythmia? If treatment is needed, the short-term use of antiarrhythmic medications is usually enough. PVC often disappears on its own within a few months. This is a rare arrhythmia in infancy that results from extra heartbeats originating in the ventricles. Premature ventricular contraction (PVC).This is a common condition that originates in the atria. Sinus tachycardia often requires no treatment, since it’s typically a response to pain, infection, or an emotional state. It starts in the sinus node and can lead to a heart rate of up to 170 bpm. This is the most common neonatal arrhythmia in newborns. While news of any heart issue can be concerning, certain neonatal arrhythmias present few - if any - health concerns and often disappear after a few weeks or months. This is a rare condition that can lead to fainting, especially when a child is excited or is physically active. Catecholaminergic polymorphic ventricular tachycardia.This is when the heart muscle takes less time than usual to relax between heartbeats. Long-QT syndrome occurs when the heart’s muscle walls take too long to relax. Some arrhythmias are due to inherited genetic mutations, such as: It’s also known as atrioventricular block and may be temporary or permanent. This refers to the blockage of an electrical impulse within the heart. When it occurs, it’s often the result of gastroesophageal reflux or immature respiratory control that may resolve on its own. Sinus bradycardia in newborns is unusual. This is a slow heart rate caused by an irregular signal coming from the sinus node, the heart’s “pacemaker” and the origin of electrical impulses that cause the heart to contract. These types of arrhythmias are less common than tachycardias in newborns. ![]() When a ventricular tachycardia episode lasts a few seconds, it is usually harmless, but longer episodes can be life threatening.Īn atypically slow heartbeat is known as bradycardia. It’s much less common than supraventricular tachycardia. This is a rapid heartbeat that originates in the ventricles. A procedure called ablation can sometimes eliminate the extra pathway. Some children born with Wolff-Parkinson-White syndrome also have a structural anomaly. This is a rare neonatal arrhythmia that develops due to an additional electrical pathway in the heart, which causes a potentially dangerous irregular heartbeat. ![]() Electrical cardioversion uses special cardioversion pads placed on your baby’s chest to send electrical impulses that return the heart to a standard rhythm. A 2020 study suggests that while atrial flutter may be a life threatening condition, early prenatal diagnosis and prompt treatment can save lives. This is an irregular beating of the heart’s upper chambers (atria) and a heart rate of between 280 and 500 bpm. A 2019 study suggests that most supraventricular tachycardias in newborns resolve on their own and that medications may be enough to manage the condition. It’s the second most common arrhythmia in newborns. This is a disturbance just above the heart’s lower two chambers (ventricles). There are a few different types of this arrhythmia, and some carry more risk than others. You can also categorize arrhythmias by the type of rhythm disturbance, such as:Īn atypically rapid heartbeat is known as tachycardia. Non-benign arrhythmias are more serious and may require treatment early in a child’s life and possibly for years afterward. They may even disappear as a child gets older. For this reason, they may not need significant treatment. ![]() Neonatal arrhythmias may be considered either benign or non-benign.īenign arrhythmias are not life threatening. What types of arrhythmias are common in newborns?
