The output of this structure is directly related to "VO­2 max" and may be used to help identify the root cause of ischemia in a patient. Shunts in this structure, such as the foramen ovale, may lead to pathological flow of matter through it. The QRS complex is produced by the action of the SA node within this organ. That node generates a pacemaker potential, which can be measured with an EKG, using which abnormalities like tachycardia may be detected. Blood flows through the tricuspid valve in this organ before entering the pulmonary circuit via the right ventricle. For 10 points, name this organ that is connected to the aorta and pumps blood.
