Right-sided and left-sided signals typically refer to the orientation of electrical signals in the context of medical imaging, particularly in echocardiography or cardiac assessments. Right-sided signals are associated with the right side of the heart, which includes structures like the right atrium and right ventricle, often reflecting conditions affecting pulmonary circulation. Left-sided signals pertain to the left side, which comprises the left atrium and left ventricle, usually indicating systemic circulation and conditions like hypertension or heart failure. Understanding these signals helps in diagnosing and managing cardiovascular diseases.
