Tachycardia means your heart beats too quickly–usually faster than 100 beats per minute. It interferes with the heart’s normal function and may increase the risk of stroke, heart attack, or even sudden death. There are several types of tachycardia that are named according to where the problem is located (atrial/in the upper chambers or ventricular/in the lower chambers).
An irregular heart rhythm that begins in the upper chambers of the heart. Afib is very fast, chaotic atrial rhythm.
A heart rate that’s fast but regular. It means there is a problem in the electrical circuit in the atria (the upper chambers of your heart) that leads to weaker heart contractions.
A fast, regular heart rhythm that starts in the upper chambers of the heart and could be the result of a structural problem in the heart that you may have been born with.
A series of fast or uneven heartbeats usually caused by a heart defect you were born with. Paroxysmal SVT and Wolff-Parkinson-White syndrome are forms of SVT.
The lower chambers of the heart contract weakly affecting the heart’s ability to pump blood. It can be fatal if the normal rhythm isn’t restored quickly.
The ventricles beat very quickly and can lead to ventricular fibrillation. It’s usually seen in patients with coronary heart disease, a heart valve problem, or cardiomyopathy.
