The normal pulse rate of adults is between 60- 100 beats/min, which is consistent with the heart rate. This is the pulse rate of normal adults in a quiet state. If the pulse rate is greater than 100 beats/min, it is a fast pulse rate, also known as tachycardia. If the pulse rate is less than 60 beats/min, it is a slow pulse rate, also known as bradycardia.
There are two kinds of tachycardia, one is physiological tachycardia, such as drinking strong tea and coffee, and the heart beats faster after drinking. This situation does not need to be dealt with. The other is caused by diseases, including heart diseases, such as atrial fibrillation, atrial flutter, ventricular tachycardia, atrial tachycardia and supraventricular tachycardia. These are all arrhythmias, which require urgent medical treatment, and surgery can be considered if necessary. There are also tachycardia caused by diseases other than the heart, such as hyperthyroidism, anemia, bronchial asthma, emphysema and pulmonary heart disease.
Bradycardia can be seen in two situations. One is physical. For example, a friend or athlete who loves sports usually has a heart rate of 50-60 beats/minute, and his heart rate will be very fast after the activity, so he doesn't need treatment. The other is caused by disease. There are two common diseases, one is sick sinus syndrome and the other is atrioventricular block. Both of these conditions will lead to severe bradycardia and require the installation of permanent artificial pacemakers.
I hope my answer can help you!
