What are inherited rhythm disorders?
People who have inherited rhythm disorders (IRDs) experience irregular heartbeats, also known as arrhythmias. Once diagnosed, IRDs can be managed through treatment and medication. However, IRDs can lead to complications such as fainting and seizures.
In some cases, IRDs may also lead to sudden arrhythmia death syndrome (SADS) in people of all ages, including children and young adults who are otherwise healthy and have no medical history of a heart condition.
What are the symptoms of inherited rhythm disorders?
You may or may not experience symptoms. However, IRDs are an underlying cause for SADS. The most common warning signs for SADS are:
- Fainting or seizure during physical activity
- Fainting or seizure from emotional excitement, emotional distress, or being startled
- Family history of unexpected sudden death during physical activity or during a seizure, or any other unexplained sudden death of an otherwise healthy young person
