Rate-corrected QT interval: techniques and limitations. The duration of the QT interval on the surface electrocardiogram represents the time required for all ventricular depolarization and repolarization process... C Funck-Brentano,P Jaillon - 《American Journal of Cardiology》 被引量: 597发表: 1993...
We sought to determine whether the relationship between heart rate (HR) and QT interval (QT) differs as HR increases in response to exercise, atropine and isoproterenol. Background Autonomic nervous system influences on repolarization are poorly understood and may complicate the interpretation of QT ...
BACKGROUND: Physiological changes in the QT interval caused by sleep are important in the evaluation of the normal QT interval. Traditionally, Bazett's formula is used for correcting the QT interval for heart rate in childhood. We set out to establish the QT-RR relationship in infants during ...
Torsade de pointes (TdP) is a life threatening cardiac arrhythmia that is typically associated with prolongation of the QT interval. A wide variety of nonantiarrthymic medications may trigger TdP in patients with prolonged QT interval, only a few reports have described an association between TdP ...
Prolongation of the QT interval has been associated with increased vulnerability to ventricular arrhythmias and implicated as a mechanism for the Sudden Infant Death Syndrome (SIDS). Since QT prolongation may result from imbalance of the cardiac sympathe
