Endocrine tachycardia
**Tachycardia** – (the normal heart rate for a person is 60-90 beats per minute), this is a heart rate of more than 85-95 beats per minute, respectively, the pulse rate is higher than 50. The higher the heart rate, the shorter the rest of the heart. The causes of tachycardia can be different. According to the classification, tachycardia is called **sinus tachycardia (associated with the sinus node)**. In other cases of tachycardia, rhythm and conduction disturbances are diagnosed.
Tachycardia usually indicates pathology. Like bradycardia, tachycardia is not considered a diagnosis, but rather a symptom of a particular disease. Although an increased heart rate is observed not only during illness, but also during physical activity, in a general blood test and other laboratory tests. Therefore, they do not talk about heart rhythm, but about tachycardia as a phenomenon: regardless of the cause, it indicates disturbances in heart rhythm. However, despite the term “tachycardia,” not a single medical manual contains this term as an independent diagnosis, because tachycardia is just a manifestation of a disease, that is, a symptom. And if the patient is informed that he has tachycardia, doctors always clarify what kind of tachycardia is observed in the person. Manifestations of tachycardia are accompanied by rapid heartbeat. The pulse can be weak or strong, depending on the intensity of excitability of the heart muscle. In this case, the heart beats as if on its own, like crazy. The causes of tachycardia are extremely diverse, and all of them can be divided into two large groups: pathological and physiological. The main pathological causes of tachycardia:
