I am a white middle class male, semi retired, age 68 - taking only a baby aspirin each day. I have a throbbing headache, my heart is skipping beats and I feel very weak all over. My blood pressure is currently 128/61 and pulse is 73. I have had and been treated for a fib in the past and there is a history of stroke and heart attack in my family. I don t drink alcohol or smoke. I have been drinking coconut water, hoping it would help lessen the symptoms. What is the difference between PVCs, PACs and AFIB? I d like to be able to tell the difference and know what I can do to help myself or see a doctor if I actually need help. I have these episodes fairly often.
