I have mentioned the contraindications and side effects in many videos but just to make sure you got them all in one place. 

Metal implants like hip, knee and screws and plates are not a contraindication. To the contrary you will find better healing and reduced inflammation when using PEMF over these areas. 

Arrhythmia (atrial fibrillation, tachycardia or bradycardia) are not listed as contraindication but we recommend as usual discretion and a slow start. Use the low settings to see effects and only when you are sure there are no complications increase the output. Many patients have noticed that Arrhythmia is reduced or disappears.

EASING INTO THERAPY is a wise move. Start slow and observe!
