The potassium postarrest was low (2.8 mmol/L), calcium and magnesium were within the normal range. Her post-arrest electrocardiogram (Panel) showed an extremely prolonged QT: 760 ms (QTc: 694 ms, rate 50 b.p.m., normal QRS-width) without evidence for acute ischaemia. After withholding ...
DCA showed that there was a maximum benefit in the threshold interval of 0-0.8. CIC showed that the prediction model could effectively distinguish high-risk of the occurrence of prolongation of the QTc interval in the threshold probability range of patients. ConclusionA column chart prediction ...
Since the initial QTc interval was normal and it came back to the normal range after discontinuation of ticagrelor, we can rule out this factor as well. Everolimus has been associated with QTc prolongation in renal transplant patients where it has been used as an immunosuppressant [16]. The ...
The mean QTc interval in 140 normal adults was 0.40 second (S.D. ± 0.02, range 0.32 to 0.44 second). It was 0.44 second (S.D. ± 0.09, range 0.32 to 0.54 second) in 125 patients with pulmonary tuberculosis. The difference was statistically highly significant (p<0.001). The QTc inter...

Finally, this chapter focuses on the classical teaching that TdP can only be diagnosed in the setting of a prolonged QT interval. However, polymorphic ventricular tachycardia with a similar twisting morphology can occur in the setting of a normal or near-normal QT interval, and generally this arr...
QTc intervals for males (A) and females (B) show normal distributions within each sex group. with an elongated QTc interval was higher in females than in males because the mean QTc interval for females was longer than for males. This pattern was observed in every age range. Table 4 ...
Aims and Objectives: To determine whether abdominal obesity is associated with a prolongation of the QT interval corrected for heart rate (QTc) on the electrocardiogram (EKG) in Indian males with normal BMI. Materials and Methods: It was a cross-sectional study involving 100 males with normal ...
This study sought to evaluate the range and variability of the QT and corrected QT (QTc) intervals over 24 h and to assess their pattern and relation to heart rate variability.Recent Holter monitoring data have revealed a high degree of daily variability in the QTc interval. The pattern of ...
To better understand it, we analyzed the QTc interval duration in patients w... Vrtovec,B. - 《Circulation》 被引量: 385发表: 2003年 Risk for life-threatening cardiac events in patients with genotype-confirmed long-QT syndrome and normal-range corrected QT intervals. This study was designed...
