Complete heart block associated with paraneoplastic hypercalcemia: a case report.

ABSTRACT:

Background

Complete heart block (CHB) means a lack of association between the atrium and the ventricle. Hypercalcemia is an electrolyte disorder that rarely causes CHB.

Case summary

Hereby, we report the case of a 59-year-old male who was admitted with general weakness. The electrocardiography (ECG) changes revealed CHB, short QT interval due to short ST segment, and generalized ST elevation.
