QTc and its importance

Fourth Frontier

Last Update vor einem Jahr

QTc or Corrected QT interval, is a measurement of a phase on the ECG measured by calculating the time duration in milliseconds from the start of the QRS complex to the end of the T-wave. Excessive shortening and lengthening of QTc interval is a vitally important component of ECG reading and is an independent risk factor for unusual heart rhythm changes. A prolonged QT interval could put a person at increased risk of sudden cardiac death if they have drugs like Hydroxychloroquine or Azithromycin.

Abnormal QT values may also be seen due to heart disease, drugs affecting the heart, genetic factors, electrolyte disturbances and requires further investigation to establish its cause.
