Familial atrial fibrillation is a hereditary feature of the heart's normal rhythm. Atrial fibrillation also raises the risk of stroke and sudden death. Atrial fibrillation complications can occur at any age, but some people with this heart disease have no health issues related to the condition.
Ankyrin-B syndrome is associated with a variety of heart disorders due to heart rhythm disruptions. Electrical signals that travel through the heart in a highly coordinated manner can regulate Heart rhythm. Individuals with ankyrin-B syndrome may have trouble with the sinoatrial node, which creates the electrical impulses that start each heartbeat. Other heart disorders related to ankyrin-B syndrome include irregular and uncoordinated electrical activity in the heart's upper chambers or lower chambers, and an abnormality named catecholaminergic polymorphic ventricular tachycardia in which an increase in the heart's upper chambers or lower chambers can cause an abnormally fast and irregular heartbeat, ventricular tachycardia. However, because additional heart abnormalities can arise from mutations in the same gene, long QT syndrome 4 is commonly associated with ankyrin-B syndrome.
An aldosterone-producing adenoma is a noncancerous tumor that arises in an adrenal gland, which is a small hormone-producing gland found on top of each kidney. By limiting the amount of salt retained by the kidneys, Aldosterone helps regulate the body's fluid levels and blood pressure. People with an aldosterone-producing adenoma can have elevated blood pressure, an elevated risk of heart attack, stroke, or an irregular heart beat.
