Un caso raro de taquicardia sinusal

A 49-year old male was referred to Emergency for sinus tachycardia and chest pain. His medical history included hypertension and AIDS. The electrocardiogram showed sinus tachycardia, right bundle branch block and S1 Q3 T3 pattern. This, together with his other symptoms and other initial complementary tests suggested pulmonary embolism. It was decided to perform an angiotomography of the pulmonary arteries, which did not detect filling defects in the main, lobar or segmental arteries. However, a large thoracoabdominal aortic aneurysm was detected, which was visible from the entrance of the pulmonary arteries to the left atrium (AI) to the exit of the superior mesenteric artery whose length was 16.5 cm and on the axial plane of 9.6 cm×13.3 cm, with compression on AI and anterior displacement of the stomach and gastric chamber, with a large mural thrombus presenting a light of 9.5 cm×4.5 cm.
