Joe Biden, 77, is in the running to be the next American president. No easy feat for anyone especially for a man of his age. With his most recent medical assessment revealed, is he healthy enough to fill those important shoes?
What is atrial fibrillation?
Atrial fibrillation is a heart condition that causes an irregular and often abnormally fast heart rate, said the national health body.
It added: “In atrial fibrillation, the heart rate is irregular and can sometimes be very fast. In some cases, it can be considerably higher than 100 beats a minute.
“This can cause problems including dizziness, shortness of breath and tiredness.
“You may be aware of noticeable heart palpitations, where your heart feels like it’s pounding, fluttering or beating irregularly, often for a few seconds or, in some cases, a few minutes.
“Sometimes atrial fibrillation does not cause any symptoms and a person who has it is completely unaware that their heart rate is irregular.”
“An older person who has an active lifestyle and is consistently being challenged cognitively can fulfil those duties,” said Dr Richard Dupee, chief of geriatrics at Tufts Medical Center.
He continued: “Someone who is 95 could have the memory of someone who is several decades younger.”
Although Biden has said he would serve only one term if elected, he is in good enough health to probably survive even a second term, according to an academic paper released by the American Federation for Aging Research.
