• Question: From all your research, can you gather the most common cause for the genes making the heart be beating too fast or too slow?

      The heart is a pump and it is beating in rhythm because it is “wired” properly so electrical activity can spread through it at a good pace.
      Some proteins are responsible to let the electrical activity spread throw the heart, they are called channels. A lot of mutations can affect those channels and make them more or less efficient.
      If the channels are more efficient in letting the electrical activity spread through the heart, it will beat faster. And obviously slower if they are less efficient.
      I hope that it makes sense 🙂
