On a normal ECG, you’ve got the P, Q, R, S, and T waves. The QT interval spans fromthe start of the Q to the end of the T wave. 解释了下什么是QT间期 Long QT syndrome, or LQTS, is when somebody’sQT interval is longer than normal, which should typically be less than half ...

Long QT syndrome (LQTS) is a congenital disorder characterized by a prolongation of the QT interval on electrocardiograms (ECGs) and a propensity to ventricular tachyarrhythmias, which may lead to syncope, cardiac arrest, or sudden death. (See Etiology,

Long QT syndrome (LQTS) is a disorder characterized by a prolonged myocardial repolarization, an abnormally long QT interval in surface (ECG) and recurrent episodes of ventricular tachyarrhythmias, which may lead to syncope, cardiac arrest, or sudden death. LQTS may be congenital or induced, but...
is the width between two nearby R peaks, and the QRS complex width is defined as the distance between Q and S wave. Other features of ECG include PR interval, QT interval, ST segment, and T wave. Accurate identification of ECG features is important for the automatic ECG analysis algorithm...
This report describes a case of a 32-year-old male, competitive athlete with atypical repolarization pattern in ECG. QTc measured in rest ECG was 610 ms and maladaptation of the QT interval duration to the changing heart rate was documented. 24-hour ECG did not show significant arrhythmias. ...
All study subjects met the ECG criteria for LVH defined by Sokolow-Lyon Voltage, Cornell Voltage or Cornell Voltage Products. ECG parameters including heart rate (HR) and QT interval (QTc by Bazett's) were evaluated. QTc prolongation was defined by QTc鈮 450ms. The function of autono...
Background: Electrocardiographic and molecular studies have clarified an association between sudden infant death syndrome (SIDS) and long QT syndrome (LQTS), and few data are available for the QT interval in infancy from birth to 1 year of age. Appropriate time of electrocardiographic screening is...
