Symptoms such as chest pain, palpitations, shortness of breath, etc. will occur after the heart has been struck. If the impact is severe and penetrating cardiac injury occurs, Baker’s triad and hemorrhagic shock will occur. 1. Blunt cardiac injury: violent impact can lead to myocardial damage, which can cause severe pain at the projection of the heart’s body surface and strangulation pain behind the sternum. Damage to the heart muscle also affects the heartbeat, resulting in irregular heartbeats, fast or slow heartbeats, and sensations such as panic and a sense of missed beats. After the heart beats abnormally, the contraction of the heart blood filling is insufficient to circulate oxygen to all organs, then the body will speed up the breathing, or even feel the lack of oxygen, and will breathe hard or open the mouth to breathe. 2. Penetrating heart injury: this is an injury caused by violence directly acting on the heart after being hit, if the injury opening is small, it will lead to blockage of blood clot and pericardial fissure, which will cause cardiac tamponade, and there will be the Baker’s triad sign such as elevated venous pressure, jugular vein fury, distant heart sound, weak heart beat, decreased arterial pressure, decreased pulse pressure difference, etc. The heart will be able to breathe faster and even feel insufficient oxygen circulation to all the organs. It causes dyspnea, shallow breathing, pallor, and a drop in blood pressure. When the pericardium and the heart crack ambassador a large amount of blood will flow into the chest cavity, which will cause dizziness and cold sweating, and even shock. Uncomfortable symptoms after the heart is hit should be sought as soon as possible, do not delay the condition, to avoid leading to adverse consequences.
