Supraventricular Tachycardia (SVT)
Normally, the compartments of the cardiovascular (atria and ventricles) contract in a coordinated manner. The contractions result from an electrical transmission that begins in an part of the heart known as the Sino atrial node (also known as the sinusitis node). The signal moves through the uppr heart sections and explains to the atria to deal. The nose node is a natural pacemaker that handles the tempo of the cardiovascular system. Electrical impulses travel from the natural pacemaker through the atria then go through a filtration system before running down specific fibers that activate the ventricles. The atria will be above the ventricles, thus the term supraventricular. The term tachycardia identifies a rapid pulse of above 100 surpasses per minute. Supraventricular tachycardia then simply is a fast rhythm from the heart that begins in the upper sections. When patients experience enhancements made on the normal pattern of electric powered impulses and an abnormal heart beat occurs, they are really having an arrhythmia.
SVT means that every now and then your the new heart beats very fast for the reason besides exercise, high fever, or perhaps stress. During an show of SVT, the heart's electrical system doesn't work proper, causing the heart to beat very quickly. The the new heart beats at least 100 is better than per minute and could reach three hundred beats per minute. After treatment or itself, the center usually results to a regular rate of 60 to 100 sounds per minute. SVT may start and end quickly, and you may not have symptoms. SVT becomes a difficulty when it happens often , continues a long time, or causes symptoms.
Most symptoms of SVT are caused by defective electrical connections in the cardiovascular system. What causes the electrical problem is not clear. SVT also can be caused by certain medicines. Examples include very high amount heart treatments digoxin or perhaps the lung medication theophylline. A few types of SVT may run in families. Or they may be caused by a lung difficulty such as COPD or pneumonia. The condition most occurs in young people or infants...
