Intense palpitations. heart rate,ct scan,ekg w/pvc,blood work normal only slightly raised d dimer,also been sick with virus. any ideas o/than anxiety?

Feel your pulse: left wrist on thumb' s side. Get a rate, count over 1 minute or half a minute. Also feel if regular/ irregular. Your symptoms suggest mild dehydration if you had a recent viral illness. Tachycardia or a fast heart rate is expected in febrile states and/or dehydration. Anxiety will make it worse. Stay well hydrated, talk to your doctor about your symptoms, have numbers for your pulse.
