Pulse near lateral malleolus of fibiula.

My father have had issue of high cholesterol and triglycerides since 15/17 years for which he took statin and since last two years he was managing it naturally with regular lipid profile , but his march test showed triglycerides of 400+ and normal cholesterol and the one he had in june showed a a 200 cholesterol and and 211 triglycerides and after covid last to last year his energy levels have dipped and suddenly while massaging his ankle i picked up his pulse near ankle (lateral malleolus fibula ) and since then i am worried he is not listening to me plus his resting plus I measured multiple times sometimes it is around 80 sometimes it is around 100 even while he is just watching tv lying on bed generally it is always above 80-90 1. Should i be worried about pulse in his lower leg and high resting pulse rate , {recently a family member of similar age succumbed to heart attack since then i am too worried although we dont have genetic heart issues } 2. Should i force him to get ecg echo
