Abstract:

Purpose: The reduced heart rate variation, which is the mitral anular calcification (MAK) mortality indicator, has been found to be associated with deteriorated P wave dispersion and atrial electromechanical delay. Considering that MAK may have potential arithmoogenic effects in our study, we aimed at researching the effects of MAK on heart electrophysiology in addition to the classic ECG parameters using new arithmoogenic indicators such as f(QRS-T) angle and Tp-e/QT. Patients and Methods: A total of 200 consecutive patients [n=100 MAK (+) and n=100 MAK (-)] were included in the study. All collected data and electrocardiogram parameters were compared between groups. Results: In the P Wave MAK (+) group, it has been observed significantly long according to the control group (p<0.001). The corrected QT interval in the MAK (+) group was significantly long followed according to the control group (p<0.001). The Tp-e interval in the MAK (+) group was significantly long followed according to the control group (p<0.001). The Tp-e/QT interval and the Tp-e/correct QT interval ratio in the MAK (+) group were significantly long followed according to the control group (p<0.001). The frontal QRS-T angle is significantly overtracted in the MAK (+) group (p<0.001). The result: Our study assessed the effects of MAK on the ECG and for the first time in literature it was found that the negative effects of MAK on the repolarization parameters of the heart.
