Many people think that a faster heartbeat is actually nothing, because it can promote blood circulation. In fact, a faster heartbeat has a huge impact on our body. First, it will cause many people to panic and feel dizzy, because people can only survive at a normal heart rate. If the heart rate exceeds the normal range of the body's tolerance, they will feel very uncomfortable. The heartbeat of a normal person is controlled by the sinoatrial node. Biologically controlled by the sinoatrial node. The electrical impulse is sent out by the sinoatrial node, passes through the special conduction tissue of the heart, and is transmitted to the atria, atrioventricular node, and finally reaches the ventricles at a normal speed. Causes the atria and ventricles to contract sequentially. This process repeated over and over is a normal heart rhythm. Normal heart rhythm is called sinus rhythm, which is 60-100 beats per minute. When the heart rate increases, more oxygen is consumed, which will cause insufficient oxygen supply to the head and lead to dizziness. There are many reasons why this may happen, such as after high-frequency exercise, stress, or hyperthyroidism. If you just occasionally feel dizzy due to nervousness and your heart rate increases, it's not a big deal. If this happens often, you should see a doctor and ask what is going on. Young people don't need to be nervous about tachycardia As we all know, the heart is an important organ in the human body. It is located in the middle left part of the chest cavity, with the sternum and ribs in front and the esophagus and spine behind. It is about the size of your fist. Throughout a person's life, the heart works non-stop without sleep. It will not stop beating until life ends. Because the heart constantly contracts and relaxes, the blood in the blood vessels can circulate continuously, allowing people to survive. When the heart beats, the apex of the heart hits the chest wall near the left nipple, forming an apex beat. People who are thin and have thin chest walls can clearly see or feel the beating heart with their hands. Under normal circumstances, an adult's heart beats between 60 and 80 times per minute, but if the heart beats more than 100 times per minute in a quiet state, it is "tachycardia", also known as "palpitations". "Tachycardia" is not a disease name, but a symptom. The causes of tachycardia vary greatly, the most common of which is a disease of the heart itself, such as various types of heart disease, myocarditis, heart failure, etc. Systemic diseases such as anemia, fever, acute and chronic infection, shock, hyperthyroidism, and gas poisoning can also cause tachycardia. For normal people, their heart rate may accelerate when they exercise or are emotionally excited, drink strong liquor, strong tea, strong coffee, smoke a lot, or take certain medications. |
