TENS (transcutaneous electrical nerve stimulation) therapy is generally considered safe and is commonly used to manage pain. However, there is a theoretical risk that TENS therapy could potentially interfere with the heart's electrical activity and promote heart rhythm disorders, especially if the electrodes are placed near the chest area. It is important for individuals with heart conditions or implanted devices such as pacemakers to consult with a healthcare professional before using TENS therapy to ensure it is safe for them. Overall, when used properly and under the guidance of a healthcare provider, TENS therapy is unlikely to promote heart rhythm disorders. **
