Tachycardia can resolve on its own, but this is typically under physiological conditions. Especially in situations of stress or emotional excitement, tachycardia can resolve on its own. However, if it is due to a pathological disease, this is not the case. Particularly, it is important to re-examine the electrocardiogram, monitor changes in heart rate, blood pressure, and pulse. If the heart rate is too fast and blood pressure is elevated, sometimes active treatment and symptom control are necessary. Additionally, if it cannot resolve on its own, it is first necessary to rule out coronary heart disease, psychological disorders, and other pathological changes that might cause this condition.
