Tachycardia, also called tachyarrhythmia, is a common type of heart rhythm disorder in which the heart rate exceeds the normal resting rate. Usually, a resting heart rate over 100 beats per minute is regarded as tachycardia in adults.
Generally, tachycardia is not fetal. The symptoms of the disease can be relieved by immediate treatments. But there is one type of tachycardia that can cause sudden death. It is called ventricular tachycardia.
In ventricular tachycardia, abnormal electrical signals in the ventricles will make your heart beat faster than normal, usually more than 100 beats per minute. When that occurs, your heart can not be able to pump enough blood to your body and lungs, which may cause sudden cardiac arrest and lead to death.
It should be noticed that not all cases of ventricular tachycardia are dangerous. In some cases, it may last for only a few seconds and causes no symptoms. While in some other cases, it may be life-threatening. The dangerous situation usually occurs in people who have other heart disorders such as heart attack or tumor.
