This disease sees more young people, age is many among 20- 35 years old, most patients, for women, some patients have illness coming on and can be prone to family's nature heredity. Sinus tachycardia is the most basic, most important manifestation of a disease. But its sinus speed and general sinus are very different in speed, have the following several characteristic: The heart rate exceeds 100 times divides while having a rest or at the time of the slight activity. P wave shape is a sinus at the time of tachycardia. The average heart rate obviously increases in 24 hours when the electric seal of dynamic heart is recorded, the trend of heart rate unusually increases for the daytime, relatively reduce at night, some cases can be dropped to normally. Lie location, relatively low heart rate ' 60- 135 times fen) ,The heart rate obviously increases while standing upright ' 90- 160 times fen) . Short time ' 5 minutes) Sport ( Walk or the plateform is tested) The heart rate does not increase suitably, the average heart rate can be up to for 140 times divide the above. Often amalgamate arrhythmia cardiac muscle ill and in heart failure in later period. In addition, this disease blocks pharmaceuticals or calcium and resists pharmaceuticals to treat reaction difference to receptor short of moneyly. Specially sending patients' weight of clinical symptom of sinus speed differs, all patients have palpitation, weak, dizzy and uncomfortable symptom of feeling oppressed etc., a few cases can faint. It faints to be may the intersection of cardiac output and hypotension of person who drop that heart rate cause soon too cause, or hypotension after taking receptor and blocking pharmaceuticals due to causes. The able to bearing amount of the patient's sports obviously drops, in later period, the slight activity may all be limited. When patient's upright body posture, tachycardia takes place, there is not body posture hypotension. In order to control the heart rate, the patient often needs to take heavier dose of receptor and block pharmaceutical and calcium and resist pharmaceuticals short of moneyly, can present the obvious side effects of these medicines at this moment, such as dizzy, myasthenia of limbs,etc.. The patient can amalgamate arrhythmia cardiac muscle ill, obstinate and in heart failure, etc in later period in China, therefore can also decline the corresponding acute lung edema, heart, heart source shock,etc. and critical symptom. The heart function extremely drops at this moment, EF value is often lower than 30%, the prognosis is extremely bad, short-term mortality is relatively high. Except sinus speed, it verifies hearts are not often other primary and organic and unusual to check by supersound, X-ray,etc., also there are not other whole body diseases of causing the sinus speed, such as first overbearing, anaemia,etc..
