Atrioventricular (AV) dissociation with an atrial rate of 68 b.p.m. and ventricular rate of 50 b.p.m., a normal axis, normal P wave, normal QRS voltage and duration, and R-wave progression, a short QT interval (293 ms) due to a short ST segment, a generalized ST elevation and normal T wave.

T wave (Figure 1). Echocardiography ruled out any cardiac structural, valvular, or functional abnormalities.
Central and large mass with a cavitation in the right lung in favour of squamous cell carcinoma of the lung. Evidence of hyper-inhalation and emphysema was also seen in both lungs.

Evidence of hyper-inhalation and emphysema was also seen in both lungs (Figure 2).
Electrocardiography pathological findings (short QT, ST elevation, and complete heart block) were also resolved after the correction of serum levels of calcium.

Pathological ECG findings (short QT, ST elevation, and CHB) were also resolved after the correction of serum calcium levels (Figure 3).
Moderately to poorly differentiated bronchial squamous cell carcinoma revealing bronchial tissue surrounded by sheets and islands of large polygonal malignant cells with intercellular bridges, showing focal areas of intra-cytoplasmic mucin (A; x200 and B; x400, H&E-stained slides).
