This man has no pulse, but he's still alive because he does not have a heart - a human one at least.
Former Czech fireman Jakub Halik is alive, thanks to a mechanical heart.
Mr Halik is the second person to have his heart removed and replaced with a series of mechanical pumps. The first person to have this surgery, Mr Craig Lewis from Texas, survived only for a month last year.
Mr Halik has made history by surviving this long - he had his surgery in April after an aggressive tumour was found growing inside his heart, Reuters reported.
He could not have a heart transplant because the drugs required for recovery could not be taken for people with his condition.
Mr Halik said: "It was hard for me, but I didn't have any other chance at all. It was acknowledged that with the tumour I can survive for about one year and I decided to fight and do it this way." His eight-hour operation was led by Czech cardiologist Jan Pirk and was performed in the Institute for Clinical and Experimental Medicine in Prague.
What makes Mr Halik's operation different is that he does not have a heart-like machine - he has two pumps.
The pumps were originally designed to keep people alive while they wait for a heart transplant and run on batteries worn externally that connect using a special cable placed under the skin, reported the Daily Mail.
But Mr Halik's case is different. He had to use two pumps because his entire heart was removed, reported Reuters.
They perform the separate tasks of the left and right sides of the heart. One pumps blood to the lungs for oxygenation while the other sends the oxygenated blood back into the circulatory system, the Daily Mail reported.
As they are pumps, they can't reproduce the pulse.

"I don't even realise it because the functions of the body are the same, only my heart is not beating and I have no pulse any more. This is the only difference, but otherwise I am functioning like a healthy man at present," Mr Halik said.
Dr Pirk said he is happy with how well Mr Halik is doing. He said: "Mr Halik has a very strong personality, and I am satisfied with the result. We didn't know how it will go and from the very beginning it was not easy, his health status was very serious and (his survival is due) to the systematic hard work of the whole team of doctors and nurses.
"Mr Halik is now in this good condition. He is doing his best, he is training hard because after two months of laying on a bed, the muscles are getting weak and he has to make them stronger."
But Mr Halik will eventually need a human heart as no one has any idea how long he can continue like this.
Dr Pirk said that the a number of infectious complications or embolism could arise, reported Czech news website iDNES.com
So, Mr Halik has been placed on the waiting list for the heart transplant.
The average wait for a heart at the Czech hospital is reportedly eight months, reported the Huffington Post.
But Mr Halik is not fazed.
Though he must carry the battery everywhere he goes, he is not confined to his bed. He said: "My usual day goes like breakfast, hygiene, then lunch and after that I have usually visit, because my family visits me every day. Then I am doing rehabilitation like walking; sometimes I go for a walk outside, which is very pleasant.
"I am looking forward to going home, to meet my whole family, my dog, to be with them again. Then in the summer, I would like to go for a holiday by the sea."
