What are common signs indicating a cardiac contusion?

The symptoms of a cardiac contusion often arise due to the trauma sustained during an impact to the chest. Chest pain is a frequent indicator of this condition, as the heart experiences bruising or injury from blunt force trauma, which can lead to significant discomfort. Additionally, arrhythmias, or irregular heart rhythms, can occur due to the altered electrical conduction in the heart muscle affected by the contusion. Signs of heart failure may also manifest if the injury is severe, as the damaged heart may struggle to pump effectively, leading to fluid buildup and other complications associated with heart failure.

The other options listed include symptoms that are less specific or more commonly associated with other medical conditions. Shortness of breath, vomiting, and fever do not directly correlate with cardiac contusion but could be indicative of a respiratory issue or infection. Palpitations, fainting, and anxiety might suggest anxiety disorders or other cardiovascular concerns but are not definitive markers of cardiac contusion. High blood pressure, sweating, and nausea could be associated with various conditions, including stress responses, but are not typical direct indicators of a cardiac contusion. Thus, the signs of chest pain, arrhythmias, and signs of heart failure are the most representative of this specific injury.
