In the field of cardiology, telemedicine allows consultations with patients through monitoring systems and remote communication analyzing the ongoing heart rates of people with pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy and subcutaneous Holter. The use of remote monitoring may save time and efforts to both healthcare professionals and patients, including their informal caregivers, reducing the number of follow up visits to the hospital and reducing the associated costs with patient follow-up, which will help to improve sustainability of healthcare services.
