case_images: Two electrocardiogram tracings of the patient. The top electrocardiogram is the tracing when the patient first presented in May 2015; showing a QRS voltage of 16 mm. The bottom electrocardiogram is the same patient's tracing in August 2016 when repeat Echocardiography showed thicker walls and reduced cavity size of the left ventricle. The QRS voltage had increased to 21 mm
