Narrative: With approximately 1:30 flight time remaining until touchdown. Passenger explained to the a FA X that she was feeling light headed and felt like she was going to pass out. FA gave her some ice and ginger ale. She stated she was feeling worse; FA asked if she needed medical assistance and she said yes. We were on the third beverage cart when I heard FA X page for medical assistance. I immediately grabbed the medlink headset and went to the front of the aircraft. There were at least 5 medical personnel passengers on the scene when I arrived (4 being MD and 1 RN). The passenger did lose consciousness and had to be carried into the forward galley. One MD passenger was a anesthesiologist and took over with getting the passengers vital signs. I had a personal pulse and O2 saturation monitor that we placed onto the passenger to keep an eye on her vitals. She was breathing and had a pulse; we gave her oxygen and she regained consciousness. During this time the MD was asking her medical history and how she was feeling as I recorded. The MD also had an app on his phone and determined her to be in atrial fibrillation. We made sure to have the AED close by if anything changed with the passenger. I updated Medlink and they recommended that we continue oxygen; give her orange juice and that medical personnel will meet the aircraft when we land. We attempted to have the passenger slowly sit up and monitor her. She kept feeling like she was losing consciousness and said she had chest pressure.  We laid her back down and the MD wanted all medical equipment we had. We opened up the EEMK and he would ask me if we had certain medication and equipment and I would find it and give it to him. They gave the passenger one 325 mg of aspirin.  The MD also gave her 630 nitroglycerin (from the EEMK) for her chest pressure. Immediately after giving her nitroglycerin; her chest pressure subsided. The MD also started an IV (but no IV fluid was given) just in case her status changed and so that paramedics could give her an IV faster and easier. The MD advised us that she needed to remain supine laying down to keep her conscious and for her own health safety. We notified the captain and he approved of her remaining supine on the floor while we landed. We moved the MD and his wife who was the RN to first class. So that if anything changed during landing; they could easily assist and speak to paramedics. We landed safely and the ill passenger when taken by paramedics.
