However, the 12-lead ECG remains the universal initial diagnostic test in the evaluation of LQTS and is subject to miscalculation, misinterpretation and mishandling. This review discusses the ...

The absolute QT interval on this ECG is approximately 640 ms which is quite long, but the QTc when accounting for the slow heart rate is about 380 ms which is normal. This is why the "corrected QT ...

This new insight about the interrelation among PERED/weight, amplitude of ECG potentials, and durations of P waves, QRS complexes, and QTc intervals in patients with CHF can be immediately ...

Due to the effects of heart rate, the corrected QT interval (QTc) is frequently used. The QTc is considered prolonged if greater than 450 ms in males and 470 ms in females. It is calculated using ...

ECG and echocardiography was done at admission ... seen in more than 50% of patients with acute pancreatitis. Prolonged QTc interval, pericardial effusion and diastolic dysfunction are associated ...
