Does tachycardia cause aortic regurgitation?

Tachycardia is tachycardia. Tachycardia does not directly cause aortic regurgitation, but may increase the risk of aortic regurgitation.

Tachycardia is when the heart beats more than normal. Tachycardia can be caused by a variety of causes, such as arrhythmia, anxiety, stress, side effects of drugs, etc. Aortic regurgitation is when the aortic valve closes and blood flows back from the aorta to the left ventricle. Aortic regurgitation may be caused by damage to the aortic valve leaflets, aortic dilation, aortic annulus relaxation, etc., so tachycardia cannot cause aortic regurgitation. However, tachycardia increases the load on the heart, causing myocardial hypertrophy, which changes the structure and function of the left ventricle, resulting in aortic annulus dilation and incomplete closure between the aortic valve leaflets, which may increase the risk of aortic regurgitation.
