Tachycardia Sinus

Tachycardia is a rapid heartbeat in which the heart contracts more often than necessary and does not allow the body to fully process the incoming blood. Tachycardia occurs both in healthy people and in patients with problems with the heart and blood vessels. Tachycardia is a more frequent pulse that does not correspond to physiological indicators at rest - up to 90 beats per minute at rest. Such a pulse can occur during physical activity or stressful conditions. This is a dangerous condition, especially if it occurs frequently or is accompanied by painful symptoms. Sinus tachycardia occurs due to dysfunction of the sinus node of the heart. Another name for sinus tachycardia is extrasystole. The causes of sinus tachycardia of the heart against a background of health can be due to various factors, including: * Rapid nervous excitement; * Intense physical activity; * Taking strong sedatives; * Other processes affecting the nervous system.

In some cases, sinus tachycardia is diagnosed in absolutely healthy people at rest and it is argued that by eliminating the factors leading to its occurrence, the pulse rate can be stabilized. Tachycardia is especially dangerous during early pregnancy, when there is a question about its preservation.
