QTc Correction - Formula for Correction of Q-T Interval for Heart Rate
Purpose: | To correct the Q-T interval for various heart rates using Bazett's formula. |
Specialty: | Cardiology |
Objective: | other testing |
ICD-10: | R00 |
Description: | The Q-T interval becomes longer in bradycardia and shorter in tachycardia. This is due to the shortening or lengthening of the myocardial refractory period. The corrected Q-T interval (referred to as the "Q-Tc") is an attempt to give the theoretical Q-T interval if the heart rate was 60 beats per minute. Bazett proposed a formula for this purpose in 1920. |
