A junctional escape rhythm may provide adequate physiological heart rate acceleration in patients with sinoatrial node dysfunction.

Junctional escape may compensate for sinoatrial node dysfunction; hypothesis-generating and should not yet change SND management.
Junctional rhythm is usually seen in the clinic with different causes. We report a case of bicuspid aortic valve accompanied by sinoatrial node dysfunction. The junctional escape beat could accelerate with physiological needs and provided for the normal needs of daily life when dysfunction of the sinoatrial node occurred, which provides a new way for the treatment of sinoatrial node dysfunction. Our findings could be potentially significant for identifying causes and choosing appropriate treatment strategies by using ECG monitoring in the clinic in the future.
