WebbLong QT syndrome (LQTS) is inherited in an autosomal dominant manner through families. This means that that the condition occurs in the presence of one genetic change (called a mutation or pathogenic variant) in one of the LQTS related genes.

WebbAbstract. Long QT syndrome is an inherited arrhythmia characterized by a prolonged QT interval and increased risk of life-threatening cardiac events, including arrhythmogenic syncope, seizures, and sudden cardiac death with a structurally normal heart. Since its first description in the 1950s, extensive researches allowed a better understanding ... Short QT syndrome is a genetic disorder caused by mutations in genes responsible for producing certain ion channels within heart cells. It appears to be inherited in an autosomal dominant pattern. Some genetic variants cause an increased flow of potassium out of the cell, while others reduce the flow of calcium into the cell. The common effect of all these variants is to shorten the cardiac action potential, reflected on the surface ECG as a shortening of the QT interval. A list of genes i…
