szívmegállást

Szívmegállás, also known as cardiac arrest, is a sudden and abrupt loss of heart function, consciousness, and breathing. It occurs when the heart's electrical system malfunctions, causing it to stop beating effectively. This prevents blood from being pumped to the brain and other vital organs, leading to rapid loss of consciousness and cessation of breathing.

The most common cause of szívmegállás in adults is coronary artery disease, which can lead to a heart attack. Other causes include severe heart muscle damage, electrical disturbances in the heart (like arrhythmias), and trauma. In children, causes can include congenital heart defects, drowning, or respiratory problems.

Recognizing the signs of szívmegállás is crucial for initiating life-saving interventions. These signs include sudden collapse, unresponsiveness, absence of normal breathing, and no pulse. Immediate action, such as calling emergency services and starting cardiopulmonary resuscitation (CPR), significantly increases the chances of survival. The use of an automated external defibrillator (AED) is also vital if available, as it can deliver an electrical shock to restore a normal heart rhythm.

The prognosis for szívmegállás depends on various factors, including the underlying cause, the speed of resuscitation, and the quality of medical care received. Prompt medical attention and effective CPR can improve outcomes, but brain damage or death can occur quickly if blood flow to the brain is not restored. Prevention strategies, such as maintaining a healthy lifestyle and managing cardiovascular risk factors, are important in reducing the incidence of cardiac arrest.
