Catecholamine-provoked microvoltage T wave alternans in genotyped long QT syndrome.

Pacing and clinical electrophysiology : PACE - 1 Aug 2003

Abstract excerpt

Macrovoltage T wave alternans (TWA) has been described in congenital long QT syndrome (LQTS). Microvoltage T wave alternans (microV-TWA) at low heart rate (HR) is a marker of arrhythmogenic risk in many conditions, but its significance in LQTS has not been established. Twenty-three genotypically...
