Cardiac arrest symptoms are visible during sudden loss of cardiac function when the heart suddenly stops beating. When a person’s heart has been stopped, he will lose his normal consciousness and also stop his normal breathing. Pulse and blood pressure absent is major cardiac arrest symptoms. Normally cardiac arrest leads to death a person within few minutes. Doctor often referred this condition as sudden cardiac death or sudden death.
Causes of Cardiac arrest symptoms
Several causes those are normally responsible for visible cardiac arrest symptoms are including:
Ventricular fibrillation is one of the major causes of cardiac arrest. Normally Ventricular fibrillation occur when the regular, normal and electrical activation of the heart muscle contraction is usually replaced by the chaotic electric activity that may causes the heart to stop beating and also pumping blood into the brain and other part of the body. Permanent death and brain damage occur if the blood flow enters into the brain. But if the flow of blood to the brain is able to restore within five minutes, then patient may keep alive. Heart attack is one of the major causes of Ventricular fibrillation. Trauma, choking, drowning and electrocution is less common causes of cardiac arrest.
Heart attack and coronary artery disease may increase the risk factor of cardiac arrest. Heart attack is not the same thing like cardiac arrest. Myocardial infarction or heart attack occur when a portion of heart muscle become die due to the deficiency of blood flow and the oxygen of a specific area into the heart. Upper body discomfort, chest pain and shortness of breath are the major symptoms of heart attack.
Major Cardiac arrest symptoms
Vomiting, nausea, chest pain, dizziness and shortness of breath are the most common cardiac arrest symptoms. Some of the people are experience these cardiac arrest symptoms before the several hour of cardiac arrest. In ninety percent of the cases cardiac arrest symptoms are list five minutes. A usually first cardiac arrest symptom is loss of consciousness or fainting. At the same time no pulse or heartbeat can be felt.
Other Cardiac arrest symptoms
- Uncomfortable pressure.
- Pain in the chest.
- Uncomfortable sensations in both or single arm.
- Uncomfortable feel into neck.
- Sudden heaviness.
- Sudden weakness.
- Aching in one or both arms.
- Shortness of breath.
- Heat and flushing or cold sweat.
- Uncomfortable sensations in stomach.
- Loss of consciousness.
- No pulse.
- Sudden collapse.
- Feel dizzy.
- No breathing.
Risk factor of sudden cardiac arrest
The major risk factors of sudden cardiac arrest are including:
People who have pervious myocardial infarction or heart attack experience have a great chance to develop cardiac arrest. It is one of the major risk factor of cardiac arrest.
Person who have poor pumping heart or heart failure experience have likely more chance to develop cardiac arrest. It is another major risk factor of cardiac arrest.
Ejection fraction or the percentage of the blood that are pumped out from the heart during each beat, it is one of the key indicator of healthy heart.
Other risk factor of cardiac arrest
- History of sudden cardiac arrest.
- Low ejection fraction.
Diagnosis of sudden cardiac arrest
Sudden cardiac arrest may diagnosis by different biological technique including:
- Electrocardiogram (ECG)
- Chest x-ray
- Exercise test (stress test)
- Cardiac catheterization
Treatment of cardiac arrest
Early cardiopulmonary resuscitation and defibrillation are the one and only way to reverse a cardiac arrest. Those lifesaving measures must institute with a five minutes after cardiac arrest. For every minute that may passes without defibrillation, then a chance of the survival decrease by seven to ten percent. The emergency medical services may able to provide the defibrillation within six to eight minutes then the survival rate for the cardiac arrest have been increased to 50%.
