Emperor Akihito diagnosed with heart disorder

Emperor Emeritus Akihito of Japan has been diagnosed with a heart rhythm disorder.

The Imperial Household Agency announced that the former monarch has supraventricular tachycardia, meaning he has a more rapid heartbeat in the upper chambers of his heart.

The 91-year-old was diagnosed at the University of Tokyo Hospital, where he had been hospitalised until 18 July. While in the hospital, he underwent tests for new medicines to treat his pre-existing heart conditions.

His new medicine is effective in treating his new disorder, but he will continue to be monitored. He has been advised not to undertake any strenuous activities for the time being.

Emperor Emeritus Akihito was initially diagnosed with heart failure in 2022. He had previously had heart bypass surgery in 2012.

Akihito reigned as Emperor of Japan from his father’s death in 1989 until his abdication in 2019. He was the first Japanese monarch to abdicate in over 200 years, and a special law had to be passed to allow for him to hand the throne to his son, Naruhito.
