A blunt cardiac injury is an injury to the heart as the result of blunt trauma, typically to the anterior chest wall.It can result in a variety of specific injuries to the heart, the most common of which is a myocardial contusion, which is a term for a bruise (contusion) to the heart after an injury.

Traumatic cardiac arrest (TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care. Even with prompt medical intervention, survival without neurological ...
Abdominal CT showing left renal artery injury. Blunt abdominal trauma (BAT) represents 75% of all blunt trauma and is the most common example of this injury. [3] Seventy-five percent of BAT occurs in motor vehicle crashes, [4] in which rapid deceleration may propel the driver into the steering wheel, dashboard, or seatbelt, [5] causing contusions in less serious cases, or rupture of internal ...
A chest injury, also known as chest trauma, is any form of physical injury to the chest including the ribs, heart and lungs. Chest injuries account for 25% of all deaths from traumatic injury. [ 1 ] Typically chest injuries are caused by blunt mechanisms such as direct, indirect, compression, contusion, deceleration, or blasts [ 2 ] caused by ...
The small window of vulnerability in the cardiac electrical cycle explains why it is a rare event. [1] Considering that the total cardiac cycle has a duration of one second (for a base heart rate of 60 beats per minute), the probability of impact trauma within the window of vulnerability is 1–3 percent only.

Blunt cardiac injury in a common injury caused by blunt trauma to the heart. It can be difficult to diagnose, and it can have many effects on the heart, including contusions, ruptures, acute valvular disorders, arrhythmia, or heart failure. [42]
Non-cardiac causes account for 15 to 25% of cardiac arrests. [44] [47] Common non-cardiac causes include respiratory arrest, diabetes, certain medications, and blunt trauma (especially to the chest). [3] [48] [49] Respiratory arrest will be followed by cardiac arrest unless promptly treated. [49]
The injury may also affect a specific organ such as the heart, which can develop an air embolism or a cardiac tamponade (which prevents the heart from beating properly). The primary indication for a resuscitative thoracotomy is a patient with penetrating chest trauma who has entered or is about to enter cardiac arrest. [4]
