Had a bit of a scare at work today, had a dizzy spell and took my pulse and bp, pulse was 137 and I wasn't doing anything but walking down the hall and going through paperwork. Called my OB and cardiologist and was advised me to go to ER that I could be afib. Long story short, got labs drawn, EKG and IV fluids.. Everything came back ok and they sent me home, heart rate still 115 when I left. Need to follow up with heart Dr, take it easy and drink plenty of fluids. Please pray for me and my son. TIA
