The normality of the heart beats rate is of sixty to one hundred beats a minute at rest. A rate that is faster than 100 beats a minute in adults is called tachycardia. People experience transient heart beats, called sinus tachycardia, as a normal reaction to some type of excitement, anxiety, stress, or just exercise. There are two other types of tachycardia and those are named supraventricular tachycardia and ventricular tachycardia. The condition of tachycardia is caused by abnormal electrical impulses that control the heart. The main symptom of this syndrome is awareness of a rapid heartbeat that is commonly called “palpitations.” Depending on the cause and extent of the tachycardia, other symptoms may include shortness of breath, dizziness, fainting, chest pain, and severe anxiety. The most effective way to prevent tachycardia is to reduce your risk of developing heart disease. Which means maintain a healthy weight, keep blood pressure and cholesterol levels under control, and don't use recreational drugs. A treatment for tachycardia really depends on the cause and type of it. Sinus tachycardia usually does not require a treatment of some sort. However, the others do.
Supraventricular tachycardia is a tachycardia that originates above the ventricles of the heart. When your heartbeat is very fast for a reason other than exercise, high fever, or stress, you may consider seeing a doctor to check of you have supraventricular tachycardia (SVT). Most cases of SVT are caused by faulty electrical connections in the heart. What causes that electrical is not clear. People with STV have no symptoms. However, some people may have palpations. It is a feeling that the heart is racing or pounding without a logical reason. A pounding pulse and the feeling of dizziness or lightheadedness is also a couple of symptoms of this disease. What you can do at home to prevent supraventricular tachycardia is limit alcohol drinks to two a day if you are male
