What is sinus tachycardia

summary

Sinus tachycardia is a heart disease, can cause many causes, may be caused by bad habits, may also be because of the disease. Now let's see what sinus tachycardia is.

What is sinus tachycardia

First, in adults, sinus tachycardia occurs when the heart rate controlled by the sinus node exceeds 100 beats per minute. This is the most common type of tachycardia, which is often associated with sympathetic excitation and decreased vagal tone. It is not a primary arrhythmia and can be caused by many reasons.

Secondly, there are many factors that affect heart rate, such as physical activity, emotional excitement, full meal, drinking strong tea and coffee; smoking and drinking can make sympathetic nerve excited and heart beat faster. As long as this situation is handled in time, the harm is not very serious. If the body position changes, such as the sympathetic nerve is excited in the upright position, the heart rate will also increase, while the heart rate will slow down in the supine position. Sinus tachycardia caused by physiological factors is usually transient and lasts for a short time.

Finally: most patients caused by physiological or extra cardiac factors do not need special treatment. The treatment of sinus tachycardia should mainly treat the primary disease, supplemented by symptomatic treatment when necessary. For sinus tachycardia caused by congestive heart failure, digitalis, diuretics and vasodilators should be used. The correction of sinus tachycardia is often used as one of the indexes to control left heart failure.
