Atrial flutter is similar to A-fib, but heartbeats are more organized.
A-fib may be temporary, but some episodes won't end unless treated. Chaotic, irregular electrical signals in the upper chambers of the heart (atria) cause a fast heartbeat. This is the most common type of tachycardia. Common types of tachycardia caused by irregular heart rhythms (arrhythmias) include: Other types of tachycardia are grouped according to the part of the heart responsible for the fast heart rate and the cause. Sinus tachycardia refers to a typical increase in the heart rate often caused by exercise or stress.
There are many different types of tachycardia.
Treatment for tachycardia may include specific maneuvers, medication, cardioversion or surgery to control a rapid heartbeat. But if left untreated, some forms of tachycardia can lead to serious health problems, including heart failure, stroke or sudden cardiac death. Tachycardia may not cause any symptoms or complications.
