Does cardiac injury cause mediastinal flutter?

Cardiac injury may cause mediastinal flutter, but not all cardiac injuries cause mediastinal flutter.

Cardiac injuries are usually caused by violence or disease, including cardiac rupture, myocardial ischemia, cardiac surgery, etc. Mediastinal flutter is a movement of the mediastinum associated with respiratory movement. It is usually caused by lung parenchyma or pleural lesions. Mild heart injury does not cause mediastinal flutter. However, in severe cases, heart injury may cause impaired cardiac function, thereby affecting systolic and diastolic function of the heart, resulting in abnormal blood flow. When heart injury causes abnormal blood flow, it may affect normal mediastinal movement and cause mediastinal flutter.

In some cases, such as multiple trauma or severe myocardial infarction, mediastinal flutter may be a serious symptom that requires emergency treatment such as mechanical ventilation, medical treatment, surgery, etc. to help the patient survive the critical period.
