Increased heart rate
Introduction
Introduction Heart rate is different for people of different ages. The younger the age, the faster the heart rate. If the heart rate exceeds the normal range, it is called the heart rate is too fast. Parents generally know that normal people will have a faster heart rate after exercise or physical labor. This is also true of children, especially when they are scared or crying.
Cause
Cause
The cause of excessive heart rate is mostly functional, and can also be seen in organic heart disease and extracardiac factors. Its production is mainly related to sympathetic excitation and decreased vagal tone. Healthy people's exercise and emotional stress can cause tachycardia. Alcohol, tea, coffee and drugs such as isoproterenol and atropine often cause sinus tachycardia. Common diseases in the disease state are fever, hypotension, hypoxia, cardiac insufficiency, anemia, hyperthyroidism, and myocarditis.

Heart rate monitoring test
Two heart rate monitoring tests: active and passive active detection electrophysiology (EP), detection and recording of electrocardiogram, stress test, passive detection, electrocardiogram (ECG) dynamic electrocardiogram monitoring, echocardiography
2. Blood test
Blood tests can help determine if ventricular tachycardia is caused by drugs or substances, thyroid problems.
High fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis can cause heart rate to be too fast, and the normal heart rate is 60-100.
Diagnosis
Differential diagnosis
It can be diagnosed according to heart rate monitoring test and blood test and clinical manifestation.
(1) Physiological heart rate is too fast: Physiological heart rate is very common, many factors affect heart rate, such as body position changes, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, agitation, drinking, smoking, Drinking tea, etc., can increase heart rate. In addition, age is also a factor, and children's heart rate tends to be faster.
(2) drug heart rate is too fast: such as sympathomimetic drugs such as ephedrine, adrenaline. Parasympathetic blockers such as atropine, caffeine, thyroxine, amphetamine, etc. can cause heart rate too fast.
(3) pathological heart rate is too fast: such as systemic diseases: high fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis can cause heart rate too fast.
