Tachycardia

Tachycardia is a quickening heartbeat. Most often tachycardia occurs when the enhanced activity of the sinus node (sinusova tachycardia), which is usually due to the strengthened influence of the sympathetic nerve. Paroxysmal tachycardia (up to 200 heartbeat in 1 minute and above) can be a result of pulses that occur in the attack outside the sinus node,the so - called paroxysmal tachycardia (see heart Arrhythmia).
Tachycardia may occur in healthy people with physical and emotional stress, eating and other (physiological tachycardia).
Tachycardia is also observed when the temperature of the body: the number of heartbeats increase by 8 to 10 beats per 1 min. each degree above 37 degrees. Tachycardia is observed in many diseases: when thyrotoxicosis, tuberculosis, anemia, heart failure at his vices, myocarditis, myocardial infarction; often occurs with nervousness. Long tachycardia adversely affect the state of the heart muscle.
Treatment of tachycardia should be aimed at eliminating its causes. When tachycardia caused by neurosis, prescribe sedatives - preparations of Valerian, monobromide camphor 0.2 g 3 times a day and Some other kinds tachycardia reliably eliminate the so-called blockers beta-adrenergic receptors (e.g., inderalla)through which the sympathetic nerve exerts its influence on heart. Beta-blockers used with caution, under medical supervision and in the absence of them contraindications.
