In adults, when the heart rate controlled by the sinus node and its frequency when more than 100 times per minute is called tachycardia. This is the most common form of tachycardia, which occurs often with sympathetic nerve activity and the decreased vagal tone. It is not a primary cardiac arrhythmia, caused by a variety of reasons. Movement may be due to physiological conditions, anxiety, agitation caused may also


occur in the application of adrenaline, isoprenaline and other medications. In fever, hypovolemia, anemia, hyperthyroidism, respiratory insufficiency, hypoxemia, hypokalemia, heart failure and other heart diseases can easily occur when the. Disease in the control triggers the primary lesion or after cure, but easy to recur.
cause
Healthy exercise and emotional stress can cause tachycardia. Wine, tea, coffee and drugs such as isoproterenol and atropine common cause of sinus tachycardia. Common in disease states because of illness, fever, hypotension, hypoxia, cardiac insufficiency, anemia, hyperthyroidism, and myocarditis. The cause of sinus tachycardia, mostly functional, but also found in organic heart disease and heart outside factors. The excitement generated mainly sympathetic and vagal tone to lower them.
1. Physiological: physiological sinus tachycardia is common, and many factors affect heart rate, such as postural changes, physical activity, food digestion, anxiety, pregnancy, excitement, fear, excitement, drinking, smoking, tea, etc., can make the heart rate. In addition, age is a factor, children are often faster heart rate.
2. Drug resistance: If sympathomimetic drugs such as ephedrine, epinephrine. Parasympathetic blocking drugs such as atropine, caffeine, thyroid hormone, amphetamines, etc. can cause tachycardia.
3. Pathologic: systemic diseases, such as: high fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis, etc. can cause tachycardia.
4. Heart disease: acute blood loss, hypotension and shock, arteriovenous fistula, heart failure, myocarditis, cardiomyopathy, pericarditis, acute myocardial infarction and a variety of organic heart disease can lead to sinus tachycardia.
Clinical manifestations
1. Palpitations, or sweating, dizziness, vertigo, fatigue, or the performance of primary disease.
2. Can induce other arrhythmia or angina.
3. Heart rate mostly between 100 and 150 beats / min, heart sounds are mostly effectively, or signs of primary heart disease.
diagnosis is based
1. Heart rate over 100 beats / min, most of the 100 to 150 beats / min, heart sounds often powerful. Performance may have the primary disease.
2. Electrocardiogram: sinus rhythm was: , , avF, 4-6 leads, P wave upright;
avR leads, P wave inversion;
The rest of the lead P wave can be vertical, can be inverted.
P wave morphology in normal, P-R interval is greater than 0.12 seconds, the frequency is greater than 100 beats / min.1. To eliminate incentives for treatment of primary disease.1. Most of the patients in the eradication of the cause or incentives, the symptoms may disappear.
2. Have a clear primary disease should be actively treated.
3. Symptoms were -blockers can be given sedatives and other drugs or symptomatic treatment, first with "A" key drug fails, then use "B" or "C".
