Heart Murmur
Heart Murmur
A Heart Murmur (pronunciation: /hɑːrt 'mɜːrmər/) is an abnormal sound heard during a heartbeat cycle. Heart murmurs are usually characterized by 'whooshing' or 'swishing' sounds that are audible via a stethoscope.
Etymology
The term 'Heart Murmur' originates from the Latin words 'cor' meaning heart, and 'murmur' meaning a low, indistinct sound.
Definition
A Heart Murmur is a sound, similar to a whooshing noise, that occurs during the heartbeat cycle. This sound is caused by turbulent blood flow within the heart or the great vessels that is audible with a stethoscope.
Types
There are two types of Heart Murmurs: Innocent Heart Murmurs and Abnormal Heart Murmurs. Innocent Heart Murmurs are harmless and are common in children, while Abnormal Heart Murmurs can be a sign of underlying heart disease or heart valve disease.
Causes
Heart Murmurs can be caused by a variety of factors, including pregnancy, fever, anemia, and hyperthyroidism. They can also be caused by conditions that increase blood flow to the heart, such as physical activity, anxiety, and stress.
Diagnosis
Diagnosis of a Heart Murmur is typically made through a physical examination and listening to the heart with a stethoscope. Additional tests, such as an echocardiogram, may be used to determine the cause and severity of the murmur.
Treatment
Treatment for a Heart Murmur depends on its cause. Innocent Heart Murmurs do not require treatment, while Abnormal Heart Murmurs may require medication or surgery to correct the underlying condition.
