  • Do not use RMT if you are suffering from a ruptured eardrum or any other condition of the ear.
  • RMT is not suitable for patients with marked elevated left ventricular end-diastolic volume and pressure.
  • RMT is not suitable for patients with worsening heart failure signs and symptoms after RMT.
  • Do not use RMT device if you have suffered from or are likely to suffer from Costochondritis (i.e., an inflammation of the cartilage that connects a rib to the breastbone)"
