When the body shows the following six signals, it is necessary to be highly alert to sudden death.
01
Recent or aggravated chest tightness
If the chest tightness after exercise suddenly appears recently, it can be relieved after rest, suggesting that you may have coronary heart disease.
If you have symptoms of chest tightness before, and the symptoms are aggravated recently, it means that the previously stable plaque may develop into large damage at any time, leading to the occurrence of acute myocardial infarction.
02
palpitations
Irregular increase in heart rate is usually the result of tachyarrhythmia.
Most arrhythmias are less dangerous and will not cause sudden death, but if they are frequent ventricular arrhythmias, there is a risk of developing ventricular fibrillation.
03
bradycardia
The beating of the heart is initiated by specific pacing cells. If the function of pacing cells becomes worse, the beating rate of the heart will be slowed down, and in severe cases, cardiac arrest will be caused.
When the heart rate is less than 50 times, the blood pressure becomes low, which is prone to long-term cardiac arrest, leading to sudden death.
04
faint
Syncope is an important precursor of sudden death. Most syncope is caused by the sudden slowdown or stop of the heartbeat, resulting in insufficient blood supply to the brain.
Sometimes syncope can recover after a few seconds, and if it can’t recover, it will cause sudden death. In case of unexplained syncope, you should be very vigilant and find out the reason as soon as possible.
05
Unexplained fatigue
Unexplained fatigue and fatigue, or accompanied by chest tightness and edema, should be alert to sudden death, which may be caused by myocarditis or cardiomyopathy.
Myocarditis is more common among young people, usually after 1~2 weeks of catching a cold, with symptoms such as fatigue, chest tightness and fatigue, which can easily cause acute heart failure. In this case, heavy physical activity and bed rest should be strictly prohibited.
06
Black eyes and numbness of limbs
Stroke is also an important cause of sudden death. If you can’t see things on one side, your limbs are numb and weak, or you walk unsteadily and feel like stepping on cotton, you should be alert to the occurrence of stroke.
Special tips
The golden emergency time of sudden death is within 10 minutes of onset.
Once the people around you have cardiac arrest,
Call 120 for help quickly.
You can do this in addition to dialing 120.
Hand-held cardiopulmonary resuscitation
Left hand, right hand, straight hand on your heart.
Depth, depth, depth of 5CM
Speed, speed, speed twice a second
And don’t let it stop
▽
Ask AED "life-saving artifact" for help!
AED is also called "stupid defibrillator"
There is a voice prompt operation throughout the process.
A few simple steps, "fool" can learn.
▽
For cardiac arrest
Use AED to cooperate with electric shock defibrillation
The success rate is as high as 90%
It is reported that timely defibrillation is the most effective way to stop sudden cardiac death.
Within 3 minutes of the patient’s cardiac arrest, the patient was quickly defibrillated by electric shock, and the success rate of defibrillation was as high as 94% only once.
How to use the AED?
Don’t worry, look down.
AED is a "stupid machine", which will automatically identify abnormal heart rhythm that needs electric shock and give it electric shock. There are only four simple steps to use: starting-connecting-discharging-defibrillation.
Sticking electrode sheet
▽
Do not touch, analyze the heart rhythm and give defibrillation.
▽
Special reminder:
① Follow the diagram to start the machine.
② Stick the electrode pad and plug it in. The voice prompts that the heart rhythm is being analyzed. Please do not touch the patient.
After the AED is turned on, it can never be turned off, which has nothing to do with whether the patient is saved! You can’t turn it off if you save life! Only when the professional medical personnel arrive and replace the AED with a manual defibrillator can the electrode pads of the AED be removed.
