Abstract： Highdensity mapping is a new technique coming out in recent years, which is based on three-dimensional electroanatomical mapping and multielectrode mapping. It is faster and more effective in diagnosing and treating arrhythmias including atrial fibrillation, atrial tachycardia and ventricular tachycardia than the previous techniques. Meanwhile, this technique also provides a new perspective of understanding the electrophysiological mechanism of these arrhythmias. This review intends to briefly introduce the present situation and future development of highdensity mapping technique.
