Abstract

The notched T wave is considered 1 of the diagnostic signs of long QT interval syndrome (LQTIS). The investigators report observations of notched T waves in noncarrier members of families with LQTIS and compare the exercise-induced dynamic behavior of these complex T-wave patterns in mutation carriers and noncarriers of 3 families with LQTIS.
