1. What about physiological tachycardia?
Many times tachycardia is caused by some physiological reasons, such as strenuous exercise and drastic changes in mood. If this is the case, there is generally no need for special treatment. As long as you have a good rest, you will soon return to normal.
Second, what about pathological tachycardia?
1. First-aid method of neck compression
At the same level of our neck and the upper edge of thyroid cartilage, there is a place where the carotid pulse is the most obvious. If tachycardia occurs, you can touch this place with your hand and press the back of the cervical vertebra with your second, third and fourth fingers. The suggestion is to press the sensitive right side first, and then press the left side for about 10 second. You can't press on both sides at the same time, you must press on one side. If you find that your heartbeat is slow, you need to stop pressing immediately.
2. Eye pressing first aid method
If tachycardia occurs, the patient can close his eyes, then touch the eyeball with the pulp of the middle finger from the upper edge of the orbit, first with the left eye, then with the right eye, and press the eyeball 10~20 seconds each time. However, if you have high myopia or glaucoma, do not use this method.
Step 3 blink first aid
During tachycardia, the patient can sit in a chair, keep his upper body upright and his neck fixed, and then start rolling his eyes. Let the eyeball turn left as far as possible, then turn right as far as possible, and keep switching about 30 times per minute for 2~3 minutes. After turning around, focus your eyes on the tip of your nose for about one minute.
