Living with Junctional ectopic tachycardia
A very rare heart rhythm condition present from infancy in which the heart beats too fast, nonstop.
Understanding Junctional ectopic tachycardia
It starts in newborns and infants. The heart beats too fast without stopping (incessant tachycardia). GARD notes it can be associated with a disease of the heart muscle (cardiomyopathy).
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Fast, nonstop heartbeat
- Irregular heart rhythm (arrhythmia)
- Disease of the heart muscle (cardiomyopathy)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
