An endocardial murmur, also known as a cardial murmur, refers to an abnormal sound heard during a heartbeat. This condition may arise due to various cardiac issues and can be indicative of underlying heart problems. Synonyms or alternative terms used to describe an endocardial murmur include systolic murmur or diastolic murmur, depending on the phase of the heartbeat when the sound is heard. Additionally, physicians may use terms like valvular murmur or aortic murmur to specify the heart valve involved. Although these synonyms describe the same phenomenon, it is crucial to consult a healthcare professional for accurate diagnosis and appropriate treatment.
