Heart Rhythm 101

• The Heart has 3 Main Electrical channels that
  fire with every heart beat
• Sodium (Na), Potassium (K), Calcium (Ca)
• These 3 channels are in perfect balance, and
  when they are out of balance, heart rhythm
  problems arise.
• These heart rhythm problems are usually heart

• Patients may experience blackouts (heart rhythm
  goes back to normal), cardiac arrest (heart
  requires a shock to return to normal) or die
  suddenly
