For a friend, hypothetically, how would thou get their heartbeat to pick up onto Discord? My 103 year old son has severe cardiac diabetes and needs to know if he has an irregular heartbeat. Thanks in advance! [tex]\lim_{x \to \five} 5_n[/tex][tex]\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
