Cardiopulmonary resuscitation should be performed in case of sudden cardiac death, but if it can be found before sudden cardiac death and effective measures can be taken in time, the prognosis of patients will be greatly improved. This article will talk about sudden cardiac death to help you identify it as soon as possible. Sudden cardiac death is a sudden death caused by tachycardia or ventricular fibrillation caused by various heart diseases, and the heart can not contract and supply blood normally, resulting in the failure of various organs to operate normally.
I don’t know if you have seen the old-fashioned water pressure well. If you press the water pressure well regularly, you can pump up the water source continuously. The normal beating of the heart is like pressing the water pressure well regularly, so that the blood returning to the heart can be continuously pumped to all parts of the body; Tachycardia is like pressing the pressure well very quickly, and the water is pressed down again before it is completely pumped out, so the normal pump blood volume cannot be reached during tachycardia; Ventricular fibrillation is like shallow and fast pressing the water pressure well. The rhythm is completely disordered.
Naturally, the heart cannot pump blood normally. In this way, the blood cannot circulate normally, and the function of various organs will be affected due to insufficient blood supply. For example, if the brain loses blood supply for more than 8 minutes, irreversible brain death will occur.
There are signs of sudden cardiac death
Although sudden cardiac death is a sudden attack, most of them still have traces to follow.
1,Identify high-risk groups
First, we can identify high-risk groups of sudden cardiac death, that is, people with primary diseases or incentives.
Research shows that the incidence of sudden death in patients with coronary heart disease, heart failure, cardiomyopathy and previous history of sudden death will be 5 ~ 10 times higher than that in the general population. These patients belong to high-risk groups.
No coronary heart disease was found, but patients with coronary heart disease who had high risk factors such as hypertension, diabetes, hyperlipidemia, obesity and smoking, as well as those who had strong sports, emotional excitement, overworked and late nights, were also at high risk.
2,There will be heart symptoms before the attack
Most patients with sudden death will have cardiac symptoms before the attack. At this time, if we can intervene in time, it may prevent the deterioration of the situation.
Possible symptoms include chest tightness, chest pain, palpitation, poor breathing, dizziness, sweating, unexplained nausea and vomiting, as well as atypical angina pectoris, such as abdominal pain, toothache, left shoulder pain, etc.
46% of patients have chest pain, which is common after activity or under pressure, and can be relieved after rest; Dyspnea occurred in 18% of patients, who often had a history of heart failure or lung disease; Influenza like symptoms occurred in 10% of patients; 20% of patients had abdominal or other symptoms; Syncope occurred in 5% of patients; Palpitations occurred in 5% of patients.
In case of chest pain lasting for more than 15 minutes and other symptoms of suspected myocardial infarction, on-site first aid should be carried out immediately.
First, ask the witness to call 120 ambulance and transfer to the hospital. Do not drive to the hospital by yourself. In the absence of professional medical personnel, monitors and defibrillation equipment, in case of ventricular fibrillation, rescue will be very difficult.
Patients should immediately rest on the spot, prohibit walking, stop all activities and relax the whole body. You can take the posture of sitting or lying, and take your own comfort as the standard. Try to keep calm and avoid being too anxious and excited. Any slight activity or even tension will lead to increased cardiac oxygen consumption, aggravate myocardial ischemia, and increase the probability of adverse consequences such as ventricular fibrillation.
If you carry nitroglycerin with you, under the condition of ensuring that the blood pressure is not low, the heart rate is not slow, and there is no glaucoma, consult the emergency personnel and consider taking 1 ~ 2 tablets under the tongue. If not, do not take more nitroglycerin tablets.
In case of cardiac arrest, the witness shall carry out cardiopulmonary resuscitation under the telephone guidance of 120 emergency personnel, starting from external chest compression, and the ratio of external chest compression to artificial respiration is 30:2.
Although sudden death occurs suddenly, most patients have high-risk factors. Chest pain, dyspnea, abdominal symptoms, influenza like symptoms, syncope, palpitation and so on occurred within 1 ~ 3 months before sudden death. If you are a high-risk group of sudden cardiac death, once you have these symptoms, don’t hesitate to see a doctor immediately. Although sudden cardiac death is terrible, most of them have traces to follow. If we know more about the symptoms and treatment methods of sudden cardiac death, we may save one more life.
