The lack of blood flow to the brain and other organ can cause a person to lose consciousness, become disabled or die if not treated immediately. Is cardiac arrest the same as a heart attack? The answer is no, as per the Heart Organization, a heart attack occurs when blood flow to the heart is blocked, whereas in a cardiac arrest, heart suddenly stops beating. What Are The Symptoms Of A Cardiac Arrest?In some cases of cardiac arrest, there may be no symptoms at all. You may experience these symptoms prior to cardiac arrest:FatigueDizzinessShortness of breathNauseaChest painHeart palpitations (fast or pounding heart beat)Loss of consciousnessSymptoms of cardiac arrest can be life-threatening.What Causes A Cardiac Arrest?Common Causes of Cardiac Arrest:Arrhythmia and Ventricular FibrillationArrhythmia refers to an irregular heartbeat caused by disrupted electrical signals in the heart. One of the most dangerous types is ventricular fibrillation—a rapid, chaotic heartbeat in the ventricles. Instead of pumping blood effectively, the heart quivers, leading to sudden cardiac arrest.Enlarged Heart (Cardiomyopathy)Cardiomyopathy occurs when the heart muscle becomes enlarged—either dilated or thickened—resulting in weak or abnormal heart contractions. This condition increases the risk of heart failure and cardiac arrest.Coronary Artery Disease (CAD)CAD is caused by plaque buildup that narrows and hardens the coronary arteries, restricting blood flow to the heart. If untreated, it can lead to arrhythmias or heart failure—both of which can trigger cardiac arrest.Other Potential Causes of Cardiac ArrestSevere blood lossValvular heart disease (damage or defects in the heart valves)Lack of oxygen (such as from drowning or choking)Electrolyte imbalances, particularly high levels of potassium or magnesium, which can disrupt heart rhythm and lead to arrhythmiaEarly diagnosis and timely medical intervention are critical in preventing these conditions from progressing to cardiac arrest.
