The QT interval on an electrocardiogram signifies the time required for the heart to repolarize after depolarization. It has long been appreciated that a long QT interval predisposes patients to ...

A short QT syndrome should be considered in the presence of a QTc interval <340 ms and no evidence of secondary QT interval shortening.70 The identification of an abnormally short QT interval in an ...

The problem – Short QT syndrome (SQTS) was first described by Gussak et al in 2000 1 and is defined as an autosomal dominant inherited electrical abnormality of the heart characterised by short QT ...

Objectives The short QT syndrome is a cardiac channelopathy characterised by accelerated repolarisation which manifests as a short QT interval on the ECG. The definition of a short QT interval is ...

Cardiac analysis (12-lead ECG) indicated the patient had Brugada-like ECG and was diagnosed by a cardiologist as also having a short QT interval (QT=320 ms, HR=71 bpm).

They noted the persistence of the increased QT 509±54 ms (range, 384-650 ms) with dynamic fluctuations (QT low-point) around day 14 (428±22 ms vs 533±36 ms; P <.001).

Short QT interval (QTc <320 ms). ST-segment depression ( > 0.5 mm in two or more leads). Pathologic Q waves (>3 mm in depth or >40 ms in duration in two or more leads, excluding III and aVR).
