Tachycardia is a faster than normal heartbeat.
Sinus tachycardia can develop in a healthy person during physical activity or nervous excitement. It may also be associated with any disease accompanied by an increase in temperature.
Some types of arrhythmias themselves can lead to the development of tachycardia. This is called ectopic tachycardia.
With ectopic tachycardia, cardiac excitation comes from ectopic foci located outside the sinus node. This leads to an increased heart rate.
Thus, tachycardia is the general name for a rapid heartbeat that can be caused by both physiological and pathological reasons.
Tachycardia is a rapid heartbeat compared to the normal state of the body. Rapid heartbeat can occur not only as a result of physical exertion, but also as a result of nervous shock. But tachycardia does not always manifest itself independently. Often it is a consequence of other diseases, for example, fever, certain types of cardiac arrhythmia.
Sinus (sinus) tachycardia is observed in healthy people during physical exertion, emotional outbursts, and states of shock. It may be a symptom of a disease that manifests itself in the form of increased blood pressure (hypertension), respiratory tract infection, pneumonia, acute heart failure, and increased body temperature. In addition, ectopic (non-sinus) tachycardia can be transmitted directly through certain types of arrhythmia. Its causes are often associated with a lack of oxygen (hypoxia), the death of neurons due to acute mental trauma, and diseases affecting the mental sphere. It also occurs in older people due to slower myocardial function.
What is tachycardia? Tachycardia is periodic contractions of the heart, the frequency of which exceeds 90 beats per minute. In medicine, tachycardia is a condition in which the heart beats faster than normal. Exceeding the normal heart rate (HR) is observed only in some people
