Andersen-Tawil Syndrome

Summarized by Plex Health
Last Updated: 03 May 2022

Andersen-Tawil syndrome is a disorder that causes episodes of muscular tissue weak point, changes in heart rhythm, and developing abnormalities. Muscle mass strength usually returns to normal in between episodes. Mild muscle weakness might eventually become long-term. In people with Andersen-Tawil syndrome, the most common changes influencing the heart are ventricular arrhythmia, which is a disruption in the rhythm of the heart's lower chambers, and lengthy QT syndrome. Long QT syndrome is a heart disease that causes the heart muscular tissue to take longer than normal to recharge between beats. The uneven heartbeats can lead to discomfort, such as the feeling that the heart is skipping beats. Physical irregularities connected with Andersen-Tawil syndrome generally affect the face, other parts of the head, and the limbs. Some affected people also have short stature and an abnormal side-to-side curvature of the back. The signs and symptoms of Andersen-Tawil syndrome vary commonly, and they can be various even among affected members of the same family.
