PQ Segment Depression in Short QT Syndrome Patients: A Novel Marker for Diagnosing Short QT Syndrome?

摘要

BACKGROUNDPatients with a short QT syndrome (SQTS) have an increased risk for atrial, ventricular tachyarrhythmias and/or sudden cardiac death. PQ segment depression (PQD) is related to atrial fibrillation and carries a poor prognosis in the setting of acute inferior myocardial infarction and is a well defined ECG marker of acute pericarditis.
