case_images: Initial EKG showed sinus tachycardia at 107 beats per minute, first-degree heart block, RBBB, and S1-Q3-T3 pattern (Figure 1).
case_images: The 12-lead EKG shows sinus rhythm at 70 bpm, intermittent second-degree Mobitz type II AV block, and right bundle branch block. EKG: Electrocardiogram

case_images: Once hemodynamically stable, CT pulmonary angiography revealed acute pulmonary emboli bilaterally within the pulmonary arterial tree, including a large saddle embolus within the right and left main pulmonary arteries (Figure 3). 
case_images: The 12-lead EKG shows normal sinus rhythm at a rate of 75 bpm and left ventricular hypertrophy with secondary T wave inversions in the lateral leads. Note the resolution of the right bundle branch block, first-degree AV block, and second-degree AV block.. AV: Atrioventricular
