Sinus tachycardia. What do you mean?

Sinus tachycardia is the rate at which sinoatrial impulses are formed in adults at more than 100 beats per minute, usually between 101 and 160 beats per minute. Sinus tachycardia begins and ends with a gradual increase and decrease in heart rate. Sinus tachycardia is a common arrhythmia that can be caused by exercise and emotional stress in healthy people. Alcohol, tea, coffee, and drugs such as isoprenaline and atropine often cause sinus tachycardia. In the disease state, the common causes are fever, hypotension, hypoxia, cardiac insufficiency, anemia, hyperthyroidism and myocarditis. The asymptomatic sinus tachycardia generally does not need treatment. The treatment of symptomatic sinus tachycardia should mainly treat the primary disease, supplemented by symptomatic treatment when necessary. It is suggested that patients must go to the hospital for examination in time when they show symptoms, diagnose the cause, and treat them accordingly. It is suggested that patients should prevent smoking, drinking, drinking tea and coffee, prevent strenuous exercise, do not overwork, maintain an optimistic attitude, and cooperate with persistent treatment.
