On the 6th day, the QTc gradually returned to be within the normal range after discontinuation of moxifloxacin. The prolongation of QT interval in the patient was considered to be associated with moxifloxacin and amiodarone. 关键词 莫西沙星 / 胺碘酮 / 长QT综合征 Key words Moxifloxacin / ...

Fridericia QTc = QT/RR 1/3 Widely used; may give more consistent results at fast heart rates Linear Framingham QTc = QT + 0.154(1-RR) May have more uniform rate correction over a wide range of heart rates Hodges QTc = QT + 1.75(HR-60) Rautaharju May have more uniform rate correctio...
互联网 Objective To investigate the mechanism underlying the changes ofQTinterval. 目的探讨QT间期发生变化的内在机理. 互联网 QTand QTc of electrocardiogram were also prolonged, but in normal range. 心电图QT、QTc有所延长, 但在正常范围内.
The Bazett formula (QTc=QT/RR½) is one of them. • Normal QTc interval is 350–450 ms in males and 360–460 ms in females. • QTd is the difference between the longest and shortest QT interval on standard ECG. View chapterExplore book The Telemetric and Holter ECG Warehouse to ...
Risk for life-threatening cardiac events in patients with genotype-confirmed long-QT syndrome and normal-range corrected QT intervals. This study was designed to assess the clinical course and to identify risk factors for life-threatening events in patients with long-QT syndrome (LQTS) wit... I...

Indeed, the consequences of missing the LQTS diagnosis in a genetically affected individual or family member with a normal QTc can literally become a question of life or death. In a genotype-positive family, especially with a history of sudden death, it becomes essential for a clinical ...
