What are the risks of NOT getting a heart device, like an ICD or CRT-D?

Patients who are indicated for a ICD are at higher risk for sudden cardiac arrest (SCA). The ICD is implanted to help protect the patient from sudden cardiac arrest. For patients who are indicated for a CRT-D, the lower chambers of their heart do not beat in synchrony, which may reduce the amount of oxygen and blood pumped to the body. Patients are at a greater risk of worsening heart failure and SCA if they don't get a CRT-D. You should speak with your doctor about what your specific risks of NOT getting a heart device are.
