I feel lightheaded and sometimes I can feel my heart beat fast, like a quick pulse, all this started today?

Starting this morning I felt lightheaded and it hasn't ceased all day. In additon I can feel my heartbeat without actually touching my chest and if I focus on an object I can actually see it. Also about every 2 minutes or so I feel a quick jump or pulse of my heart beat lasting maybe 2 to 3 seconds. I am not queasy and I have tried resting but it doesn't help. Earlier in the day I had a dull headache and I have had plenty of food and drink. Overall there is no pain but I can't function because it limits me enough that I can't accomplish tasks. Thank you in advance. Please help!
