Although people often use the terms “cardiac arrest” and “heart attack” interchangeably, they refer to two distinct medical emergencies that require different treatments. Understanding the difference can be lifesaving.
A cardiac arrest occurs when there is a sudden electrical malfunction in the heart, causing it to stop pumping blood. It happens without warning and requires immediate intervention with CPR or defibrillation to restore the heart’s rhythm. Symptoms of cardiac arrest include sudden collapse, loss of consciousness, and an absence of a pulse. Without swift medical intervention, brain damage and death can occur within minutes.
On the other hand, a heart attack happens when blood flow to the heart muscle is blocked, usually due to a blockage in the coronary arteries. The heart continues to beat, but the affected muscle may suffer permanent damage if blood flow isn't restored quickly. Heart attack symptoms tend to develop more gradually and may include chest pain, discomfort in the arms, neck, or back, shortness of breath, and lightheadedness.
Having the proper understanding of these conditions allows for quicker, more effective responses. Cardiac specialists use advanced technologies and treatments to handle both emergencies, from rapid response care to long-term management and rehabilitation. Knowing the difference between cardiac arrest and heart attack can help save lives and lead to better outcomes during critical moments.
