ABSTRACT
Objective:
To analyze the electrocardiographic (ECG) characteristics in patients with primary hyperparathyroidism (PHPT) and meanwhile, to explore the relationship between ECG abnormality and serum calcium level in relevant patients.Methods:
Our study included 2 groups Observation group,n=84 PHPT patients treated in our hospital from 2010-01 to 2014-04 and Control group,n=80 normal subjects from regular physical examination at the same period. The ECG manifestation was compared between 2 groups. Meanwhile, according to tertile levels of serum calcium, PHPT patients were further divided into 3 subgroups①Ca2+ level (2.0-2.8) mmol/L,②Ca2+ level (2.8-3.1) mmol/L,③Ca2+ level >3.1 mmol/L andn=28 in each subgroup. The ECG abnormalities were compared among 3 subgroups and the relationship between ECG changes and serum calcium levels were studied.Results:
The ECG abnormality rates in Observation group and Control group were as 83.3% vs 18.8%, P<0.001. Compared with Control group, Observation group presented more frequent ST-T changes, QRS duration widening, high left ventricular pressure and QT interval shortening,P<0.001 orP<0.05. In observation group, with the rising of serum calcium, the incidences of ST-T changes and high left ventricular pressure were increased accordingly, the ST-T changes among 3 subgroups were significant,P<0.05; while with the rising of serum calcium, the QT interval was shortened and QRS duration was widened accordingly, the differences were obvious among 3 subgroups, allP<0.05.Conclusion:
PHPT patients have the higher incidence with abnormal ECG, while ECG abnormality has beenrelated to serum calcium level in relevant patients.
