case_images: 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.

case_images: T wave (Figure 1). Echocardiography ruled out any cardiac structural, valvular, or functional abnormalities.
case_images: 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.

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

case_images: Pathological ECG findings (short QT, ST elevation, and CHB) were also resolved after the correction of serum calcium levels (Figure 3).
case_images: 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).

case_images: The patient underwent bronchoscopy, and finally, SCC of the lung was confirmed based on pathological findings (Figure 4).
