Good day! I have been working as a teacher for 34 years and lately, when I teach a lesson, I get a palpitation, so fast that I even have a 'dull' pain in my left arm and left leg and I have to sit down. It's the same when I raise my voice, even as I climb the stairs. What do you think this heartbeat is due to

It may be a lack of magnesium. Buy a magnesium supplement from the pharmacy and drink a high dose (300-400 mg) for 1-2 weeks, if this does not help go to the doctor to examine you.
