Ventricular tachycardia is a very fast heart rhythm that begins in the ventricles. The electrical impulses control the heart’s pumping action rate. It can develop because of problems with your heart's electrical system. When something goes wrong and signals are sent too quickly, it can cause tachycardia. This condition is caused when the upper ventricles of heart operate abnormally, interfering with electrical signals, which causes the upper heart to beat early.

Tachycardie, des symptômes qui peuvent inquiéter. Sinus tachycardia is when the sinus node in the heart sends electrical impulses faster than the normal rate, resulting in an increased heart rate. Tachycardia can be caused as a result of any physiological process that changes the pattern of sympathetic and parasympathetic innervations received by the heart (sympathetic innervations enhance the heart rate while parasympathetic innervations lower the heart rate). Your doctor notes how your heart and nervous system respond to these changes in position. Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart). Learn more in this article.
