Common Heart Concerns in Children

Heart conditions and concerns look vastly different in children than in adults. For this reason, when a child expresses concern, it should be taken seriously but a parent should not instantly assume the very worst.

Dolly Parton Children’s Hospital pediatric cardiologist, Dr. David Hurst, shares conditions and complaints he most commonly sees and how to address these different concerns.

Chest Pain

Chest pain is a common complaint but is different medically from adults. Most chest pain is skeletal, related to gastrointestinal issues, an infection or heightened by anxiety. Because of this, parents should be reassured that it’s not always worst-case scenario. If your child is experiencing off and on chest pain, keep a diary (Ex: Is the pain after exercise? Is it during a time where they may be stressed or anxious? What would the child rate their pain?) and discuss this with your child’s pediatrician. If the pain persists or you grow more concerned, take your child to the emergency room for further evaluation.

Fainting

Fainting is also very common in children and adults. Most commonly, it can be triggered by an overreaction of the nervous system, known as neurocardiogenic syncope. This can be caused by pain, increased emotions or dehydration. To ensure your child is properly hydrated, make sure they are getting a proper intake of healthy salts and are drinking enough water (three liters) each day. See your child’s pediatrician if fainting persists.

Heart Murmurs

Before you hit the panic button, a murmur is simply a sound. Many children have innocent heart murmurs that can be heard throughout life. What’s most important is determining if it’s related to a heart defect or not. With the help of echocardiograms, the murmur can be detected and best diagnosed. Well-child physicals and exams are a great way to help stay on top of your child’s heart health.

It is best to speak with your child’s pediatrician if they are experiencing any of these common concerns. If your child requires care from a cardiologist, the team at East Tennessee Children’s Hospital Pediatric Cardiology can detect and treat problems before birth, throughout childhood and even into adult life. They are highly trained to diagnose different heart diseases, using EKGs and echocardiograms to come up with a customized care plan for your child.
