The topic Autosomal Dominant Long QT Syndrome you are seeking is a synonym, or alternative name, or is closely related to the medical condition Romano-Ward Syndrome.

Quick Summary:

• Romano-Ward Syndrome (RWS) is an inherited heart disorder characterized by abnormalities that affect the electrical system of the heart
• Main characteristic features of this medical disorder include:
  • Prolongation of the QT interval: The cardiac muscles take longer time than usual to recharge between beats
  • Ventricular tachyarrhythmia: It is a fast heart rhythm that originates in one of the ventricles of the heart
  • Torsades de pointes: An uncommon and unique type of ventricular tachycardia (a pulse rate of more than 100 beats per minute, with at least three irregular heartbeats in a row)
  • Syncope: A temporary loss of consciousness and posture described by the commonly used words such as fainting and passing-out
  • Sudden death
• It is one form of Long QT Syndrome (a condition in which the cardiac muscles take longer time than usual to recharge between beats), which causes arrhythmia; a medical condition in which heart's normal rhythm is affected or disturbed
• Abnormalities that occur in certain genes cause Romano-Ward Syndrome. The syndrome may develop spontaneously or be inherited in an autosomal dominant trait (indicating that only copy of the gene needs to be mutated to develop this disorder)
• Beta blockers are the drugs of choice for treating Romano-Ward Syndrome. When left untreated it could lead to syncope (fainting), seizures, cardiac arrest, and sudden death
