How does atrial tachycardia affect my body?

Whether or not atrial tachycardia affects your body depends on how long the abnormal rhythm lasts. When it only lasts for short periods, it's not considered dangerous. However, when you have sustained atrial tachycardia, it can cause a problem called cardiomyopathy, which can weaken and damage your heart. If cardiomyopathy isn't treated, it can lead to heart failure and death.
