What is sinus tachycardia?
Sinus tachycardia occurs when heart rate increases, usually because of some stimulus that affected the heart muscles. The causes of sinus tachycardia include severe fear, distress, exercise, fever and the use of recreational, over -the -counter medicines or prescription drugs. In many cases, sinus tachycardia is considered normal and heart rate is often reduced without treatment. However, if sinus tachycardia is more permanent, this may be the result of the basic state. If drugs of any type are connected to an increased heart rate, the habits of drug use may need to be reconsidered. The node SA can be found at the top of the right atrium of the heart. Normally creates electrical impulses that regulate the heart rhythm. Most people have a normal resting heart rhythm of 60 to 70 rhythms per minute, but Sinus tachycardia can cause the heart to beat much faster.
While fast heart rate can occur with this type of tachycardia, the heart normally works. The interval between rhythms is usually regularAnd the heart rhythm itself is usually rhythmic. Fast heart rate is usually the only symptom of this condition.

Extreme fear, anxiety or emotional anxiety can also cause rapid heart rate. The heart rate usually returns to normal after a suitable rest period or after distraction of extreme emotions.

The use of regulation, over -the -counter and recreational drugs can also lead to sinus tachycardia. Respiratory drugs onThe base of caffeine, alcohol and ephedrine can stimulate the node SA and lead to a rapid heart rate. Recreational or "street" drugs such as cocaine or methamphetamine can also increase heart rate.
