cardiac arrest symptoms

What is a Cardiac Arrest? In short, sudden cardiac arrest occurs when heart suddenly stops functioning. According to a common opinion, it differs from a heart attack, as it occurs when the blood flow to a specific portion of the heart is interrupted. On the other hand sudden cardiac arrest is caused by an irregular heartbeat (arrhythmia) which blocks blood flow. Sudden cardiac arrest can be fatal if cardiopulmonary resuscitation (CPR) or defibrillation is not provided promptly. How common is Cardiac Arrest? Unfortunately, in India, someone loses their life due to sudden cardiac arrest every minute. Although this is a serious and common problem, awareness about it among Indians is still very low. What are the symptoms of Cardiac Arrest? Recognising cardiac arrest symptoms can save precious time during an emergency. The primary symptoms are sudden and severe: Sudden collapse Absence of pulse Absence of breathing Loss of consciousness Sometimes, other cardiac arrest symptoms precede sudden cardiac arrest, such as: Chest Discomfort Shortness of Breath Weakness Palpitations (fast-beating, fluttering, or pounding heart) Since cardiac arrest symptoms aren't always noticeable, SCA can strike unpredictably and without warning. What happens right before Cardiac Arrest? Just before a sudden cardiac arrest, you may experience symptoms such as severe chest pain, rapid or irregular heartbeats, unexplained wheezing, and lightheadedness. Anyone witnessing these signs should contact emergency medical services immediately. What causes Cardiac Arrest? Cardiac arrest causes can be numerous and varied, often involving complex interactions between the heart and other bodily systems. Some of the primary cardiac arrest causes includes coronary artery disease, where the blood supply to the heart is blocked or narrowed, leading to heart tissue damage. Other significant causes include arrhythmias, which are irregular heartbeats that can disrupt the heart’s normal rhythm and function. Severe physical stress, such as a major injury, an electric shock, or extreme physical activity, can also cause cardiac arrest. Additionally, conditions such as cardiomyopathy (heart muscle disease), congenital heart defects, and electrolyte imbalances can also be a significant cardiac arrest cause. It is crucial to recognize these risk factors to help in prevention and timely treatment. What are the risk factors for Cardiac Arrest? Certain factors increase the risk of sudden cardiac arrest: Family history of coronary artery disease Smoking High Blood Pressure and Cholesterol Levels Obesity and Inactive Lifestyle Diabetes In addition to these factors, previous episodes of a sudden cardiac arrest or heart attack, personal or family history of other heart diseases, such as heart rate disturbances, heart failure, congenital heart defects, aging, and use of illegal drugs, such as cocaine or amphetamines, can also increase the risk. What are the complications of Cardiac Arrest? Since in sudden cardiac arrest the blood flow to the brain is reduced, complications such as irreversible brain damage and eventual death can occur if the normal rhythm isn't promptly restored. How is Cardiac Arrest diagnosed? Recognizing the cardiac arrest symptoms and seeking immediate medical attention are crucial in treating this condition. An immediate CPR and use of an automated external defibrillator (AED) can save lives by restoring heart rhythm. How is Cardiac Arrest treated? Emergency cardiac arrest treatment includes performing CPR and administering an electric shock to the heart using an AED. Timely and appropriate medical care can significantly improve survival outcomes. Can Cardiac Arrest be prevented? While sudden cardiac arrest can happen unexpectedly, certain measures can help reduce its risk: Eating a balanced diet Regular check-ups with your healthcare provider Avoiding Tobacco and Smoking Regular Screening for Heart Disease Maintaining controlled Blood Pressure and Cholesterol Levels In case of a risk of cardiac arrest, healthcare providers may recommend implantation of a Cardioverter (ICD) defibrillator or the purchase of an AED for home use. What can I expect if I have Cardiac Arrest? If you experience cardiac arrest, you may suddenly lose consciousness and a complete absence of breathing or pulse. Immediate medical intervention is required. If left untreated, cardiac arrest can be fatal within minutes. However, with an immediate CPR and defibrillation, there is still a chance of survival and recovery, although the effects may be long-lasting depending on the speed of treatment. The best results as possible require emergency medical care and subsequent treatment. Can a Person Survive After Cardiac Arrest? Survival after sudden cardiac arrest largely depends on prompt treatment. Every minute without defibrillation can reduce the chance of survival by 7% to 10%. Frequently Asked Questions What is a Cardiac Arrest Vs a Heart Attack? Although both involve heart dysfunction, they are not the same. A cardiac arrest is an interruption in the electrical activity of the heart, while a heart attack is a circulation problem in which blood flow to parts of the heart is blocked. Is Cardiac Arrest the same as Sudden Cardiac Death? No, they are different. While SCA refers to the sudden cessation of heart function, sudden cardiac death refers to death resulting from SCA. Is Cardiac Arrest painful? Most victims of SCA lose consciousness quickly and do not report any pain. However, some survivors may recall feeling discomfort or chest pain shortly before the event. Conclusion Sudden cardiac arrest is a medical emergency that requires quick thinking and swift action. Being aware of symptoms, understanding of the cause and understanding of the treatment method can mean the difference between life and death.

Many a time, the terms cardiac arrest and heart attack are used interchangeably, but they aren't similar. However, cardiac arrest and heart attack both are life-threatening emergencies and have many similar symptoms and preventions, but they're actually two different heart-related problems with radically different causes and treatments.  It could be said that a heart attack is a “circulation” issue and a cardiac arrest is an “electrical” problem. In order to understand the difference between these two conditions, you need to understand what happens in both of these processes. Let’s discuss the differences between a heart attack and a cardiac arrest. What is a heart attack?   A heart attack or a myocardial infarction occurs when the blood supply that brings oxygen to the heart muscle is inadequate. It often results from a blockage caused by a clot in the coronary arteries that feed the heart. If the blockage is not resolved quickly, the heart muscle begins to suffer damage or start to die. A troponin test can help detect acute heart injury Make Book Troponin I Test What are the symptoms of a heart attack? Not everyone has the same symptoms. Some people show warning signs or symptoms while others show no signs at all. Symptoms of a heart attack that people may report include: Chest pain mostly in the center of the chest Spreading of chest pain to the arms, jaw, neck, back, and abdomen Pain in the upper body Fatigue Feeling lightheaded Sweating Trouble breathing Nausea or vomiting Coughing or wheezing Palpitations  What causes a heart attack? Heart attacks are generally caused by coronary heart disease; a condition caused by a buildup of fat and cholesterol in the coronary arteries forming plaques. People with CHD may experience a heart attack if a plaque ruptures and forms a blood clot which in turn blocks the coronary artery. Risk factors like smoking, unhealthy eating habits, diabetes, obesity, high cholesterol, and hypertension may increase your risk of developing coronary heart disease. And consequently, a heart attack. What is a cardiac arrest? A cardiac arrest usually happens suddenly with no warning. It is different from a heart attack.  In a cardiac arrest, the heart suddenly stops beating; whereas in a heart attack the heart usually doesn’t stop beating. A cardiac arrest is triggered by an electrical malfunction in the heart that disrupts the heart’s normal rhythm resulting in a rapid and chaotic heartbeat, and in many cases, the heart stops beating altogether. This disrupts the blood and oxygen flow to the vital organs, including the brain and lungs, causing the person to gasp or stop breathing. One may lose consciousness and becomes unresponsive within seconds. Cardiac arrests can be fatal if it’s not resolved within minutes. What are the symptoms of a cardiac arrest? In most cases, there are little-to-no warning signs. More than half of people who experience cardiac arrest have no symptoms. Others may have the following symptoms: Sudden loss of consciousness  Blue discoloration of the face No breathing No pulse Chest pain, shortness of breath, dizziness, weakness, heart palpitations, and nausea are few warning signs that may also occur in the period before a cardiac arrest. What causes a cardiac arrest? The potential causes of a cardiac arrest may include: ventricular fibrillation, ventricular tachycardia, coronary heart disease, changes of the heart structure, respiratory arrest, pacemaker failure, choking, drowning, electrocution, hypothermia, sudden drop in blood pressure and excessive alcohol consumption, and drug abuse. A heart attack can also cause cardiac arrest. If a large enough portion of the heart is affected during a heart attack, then the heart may stop beating, leading to a cardiac arrest. What is the connection between a heart attack and a cardiac arrest?   These two different heart issues are connected.  A cardiac arrest can occur after a heart attack, or while recovery. Heart attacks can escalate the risk for cardiac arrest. It is important to note that the majority of heart attacks do not lead to cardiac arrest. But, most cardiac arrests are caused by heart attacks. Other heart conditions can also disrupt the heart’s rhythm and lead to cardiac arrest. An hs-CRP test (high sensitivity C-reactive protein) along with other tests can help assess a person’s risk for developing heart disease. Make Book CRP Test. What actions must be taken in case of a heart attack or cardiac arrest?   Call emergency services immediately so that the patient can receive treatment as soon as the services arrive. Emergency services staff are equipped and well trained to revive an unresponsive person whose heart has stopped beating. This can be done either with CPR or with the help of a defibrillator.  Using CPR and defibrillators can improve the survival rate of the patient in cardiac arrest. CPR is intended to pump the heart to get blood circulating and deliver oxygen to the organs. The defibrillator sends an electric shock to the heart aiming to restore its normal rhythm. In conclusion, there is a huge difference between a heart attack and a cardiac arrest. Heart attacks are mainly a plumbing problem because it occurs when the blood flow to the heart stops causing a part of the heart muscle to begin to die, whereas cardiac arrest is an electrical problem in which heart suddenly stops beating as a result of rapid and erratic electrical impulses and irregular heart rhythm. There is a long list of symptoms of a heart attack; on the other hand, the main symptoms of a cardiac arrest are lack of consciousness, lack of breathing, and no pulse. There are various causes of a cardiac arrest; while the primary cause of a heart attack is coronary heart disease. If you or a person you’re with is experiencing symptoms that could be either of a heart attack or a sudden cardiac arrest, seek emergency medical attention as they could be life-threatening. Considering that cardiac arrest can be reversed only if treated within minutes, it’s important to act quickly. The longer the person waits to get help, the greater the damage can occur.
