Study Arms (1)

AngelMed Guardian System

OTHER

All eligible subjects will have the AngelMed Guardian System implanted with alerting features turned ON; receive an external device which provides additional alerting; and receive training on system use.

Device: AngelMed Guardian System

Interventions

The AngelMed Guardian System detects potential ongoing ACS events, characterized by sustained ST segment changes, and alerts the patient to seek medical attention for those potential ACS events. The Guardian System is indicated as an adjunct to patient recognized symptoms.

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may not qualify if:

  • Subject (men or women) is at least 21 years of age.
  • Women of childbearing age must have a negative pregnancy test or confirmation of one of the following:
  • Post-menopause or amenorrhoeic during the past year
  • Surgical sterilization
  • Use of effective contraceptive method
  • In the investigator's opinion, subject lacks ability to respond appropriately to alarms, e.g., illiteracy, poor memory or cognitive function, dementia or other condition affecting memory function, etc.
  • Known compromised tissue at the site of lead implantation in the apex of the right ventricle, e.g., prior infarct affecting the RV apex location.
  • A permanent pacemaker or ICD is already in place or the patient is indicated for ICD or pacemaker implantation based on the guidelines published by the American College of Cardiology as Class I and IIa recommendations. Class IIb recommendations are at the investigator's discretion.
  • Subject cannot feel the IMD vibration when placed on top of the skin on the left pectoral side of the chest.
  • Subject has recurrent or persistent atrial fibrillation.
  • Subject has recurrent or persistent non-sinus cardiac rhythm, second- or third-degree atrioventricular blocks, QRS duration greater than 120 ms, Benign Early Repolarization (BER), Brugada Syndrome, (LBB, BBB, RBB) or Rate Induced BBB.
  • Subject has left ventricular hypertrophy evidenced by EKG criteria.
  • Subject has any condition preventing the subcutaneous implantation of the Guardian System in a left pectoral pouch, such as:
  • superior vena cava thrombosis,
  • subcutaneous tissue deemed inappropriate for the procedure
  • +12 more criteria
