Tachycardiais the name used to describe a rapid heart rate.
The more rapidly the sinus node fires off electrical signals, the faster the heart rate.
Sinus tachycardia is when the sinus node is producing electrical signals more than 100 times per minute.

This is especially true foratrial fibrillation, which is much more common in the elderly.
SVTtends to occur as episodes that begin and end quite suddenly, usually without any warning whatsoever.
SVT causes:
People who have SVT usually have no symptoms at all in between episodes.
Despite how badly SVT can make you feel, it almost never poses a significant risk to life.
Types of SVT
There are many different varieties of SVT.
SVT can almost always be treated effectively.
Often, it can be completely eliminated by a procedure calledcardiac ablation.
Anyone seeking treatment for SVT should see a cardiac rhythm specialist known as a cardiac electrophysiologist.
Ventricular fibrillation is the most dangerous of the cardiac arrhythmias.
When it occurs, it invariably leads to death within a few minutes unless it is stopped.
Ventricular tachycardia is another potentially dangerous arrhythmia originating in the ventricles.
Sudden death may not be immediate and may not occur at all.
The large majority of people with ventricular tachycardia have this arrhythmia as a result of CAD or heart failure.
A Word From Verywell
Tachycardias are rapid heart rhythms.
There are many kinds of tachycardia, and they vary from being completely normal and benign to beingimmediately lethal.
If you have a cardiac arrhythmia that is producing tachycardia, you should have a complete medical evaluation.
