Puncture Heart (Cardiac Penetrating Injury): Symptoms and Emergency Response

Cardiac Tamponade from Penetrating Trauma

A puncture wound to the heart (knife, gunshot, fragment) is immediately life-threatening.

Classic Signs (Beck's Triad +)

• Chest pain – Sharp, central/left.
• Hypotension – From impaired filling.
• Muffled heart sounds – Fluid dampens.
• JVD – Impaired venous return.
• Dyspnea, tachycardia, pulsus paradoxus.
• Altered mental status, syncope, cardiac arrest.

Emergency Management

1. Call 911 / activate trauma team.
2. Do not remove impaled object.
3. IV access, fluid resuscitation, blood products.
4. Pericardiocentesis (temporizing) → urgent thoracotomy/sternotomy for repair.

Survival depends on rapid transport to trauma center with cardiac surgical capability.
