Pulsing hands wrist fingers. Wasnormal!

I was normally lying on bed on my abdomen with one ofhand beneath my head and one lying on bed freely, suddenly i started to feel pulsation on my hand , first i thought its normal throbbing/twitching but then i calculated the pulse and it was my pulse felt it continuous for 30 mins and i became a little too anxious about it, and checked thebp it came 140/90 buti was anxious this could be due to anxiety because during my regular health check up at a clinic my once came 118/74 and once 128/72 , my family has hypertensive history and recently i was diagnosed with high ldl cholesterol but i am not taking statin, just on an specialized diet, i dont have any deficiency or anything its just pulsing , i dontknow since i have been having thesepulses i have been facing issue of being hypersensitive towards pulse, consulted a gp, he said nothing much, also when i lay on bed or resting onsofa i continuously feel my heart beating hard/bounding pulse but hr came 50-70 , ecg/echo in april wasnormal
