Learn about the symptoms, causes and treatments for this heart rhythm condition that is sometimes inherited.
Disease
Bundle branch block
A delay or blockage in the heart's signaling pathways can interrupt the heartbeat and make it harder for the heart to pump blood.
Disease
Myocardial ischemia
Myocardial ischemia reduces blood flow to the heart and may cause chest pain — but not always. Learn all the signs and symptoms and how to treat it.
Disease
Hereditary hemorrhagic telangiectasia
This inherited blood vessel condition can cause bad nosebleeds, strokes, bleeding in the digestive tract and anemia.
Disease
Swimmer's ear
The moisture from water left in the ear after swimming or bathing can lead to this infection in the outer ear canal.
Disease
Chiari malformation
Learn about this brain condition in which brain tissue extends into the spinal canal.
Disease
Craniosynostosis
In this condition, one or more of the flexible joints between the bone plates of a baby's skull close before the brain is fully formed.
Disease
Pseudocholinesterase deficiency
This causes sensitivity to certain muscle relaxants used during anesthesia. Muscles may stay relaxed for too long, interfering with movement and breathing.
Disease
Gaucher disease
The buildup of naturally occurring fatty substances damages the spleen, liver, bones and other tissues. Life-long treatments help manage most cases.
Disease
Down syndrome
In this genetic condition, an unusual cell division results in extra genetic material from chromosome 21. This causes delays in growth and development.
Disease
Multiple endocrine neoplasia, type 1 (MEN 1)
Learn about this rare condition that causes tumors to grow and too many hormones to be made.
Disease
Total anomalous pulmonary venous return (TAPVR)
In this heart condition present at birth, the lung's blood vessels attach to the wrong places in the heart. Know the symptoms and how it's diagnosed.
