In addition, corticoid-induced normalization of the QT interval is reported in a patient with drug-induced prolongation of the QTc interval [27].
It is associated with prolonged QT interval. Electrolyte abnormalities are one of the common causes of prolongation of QT interval.
Further details such as QT interval prolongation and functional AVB due to prolonged ventricular repolarization were accurately diagnosed by fetal magnetocardiography (fMCG).
Thus, it is preferable to monitor these patients through electrocardiography in order to calculate the QT interval.
The QT dispersion and heart rate corrected QT interval were found to be significantly increased in the children with primary mitral valve prolapse when compared with the control group (56[+ or -]16 ms vs.
The QT interval was measured as the distance between the start of the QRS complex and the end of the T wave (normal QT: 360-440 ms).
Significant prolongation of QT, corrected QT interval and increased QT dispersion was observed in patients with serum ferritin levels more than 2,500 nanogram/millilitre (pless than 0.001 each).
Ventricular repolarization may be defined using QT interval, QT dispersion, and T wave measurements.
Increased heart rate (75.72 [+ or -] 9.99 vs 99.06 [+ or -] 19.05; p<0.0001), decreased PR interval (128.48 [+ or -] 17.76 vs 120.72 [+ or -] 22.58; p=0.0126), decreased QT interval (354.30 [+ or -] 26.50 vs 336.72 [+ or -] 27.10; p=0.0001) and prolonged QTc interval (393.06 [+ or -] 21.76 vs 426.69 [+ or -] 32.73; p<0.0001) were observed in ECGs in acute stress state that were statistically significant [Table 1].
Romano Ward syndrome is an inherited condition characterized by prolongation of QT interval, evident on electrocardiogram, associated with syncope and life threatening arrhythmias and ultimately sudden cardiac death.
DIAGNOSIS: Sinus bradycardia (48 beats/min), long P-R interval (0.29 s), long QT interval (0.53 s with QTc of 0.47 s), and prominent J waves suggest hypothermia; non-specific ST abnormality.
