All visitors are required to wear masks.

For COVID-19 safety, all visitors to ChristianaCare facilities and services are required to wear masks. This includes visitors who are vaccinated. Please read our visitor guidelines before arrival.

Masks required at outpatient locations; visitors and support persons limited

All visitors at outpatient locations must be masked in alignment with the masking guidelines on our visitation policy page here. Patients at ChristianaCare’s outpatient services are advised to come to their appointments alone unless a support person is absolutely needed. If a support person is needed, such as a parent, guardian or spokesperson, we highly encourage that the support person be vaccinated. Outpatient practices are not requiring vaccination or a negative COVID test for visitors at this time.

All hospital visitors required to be vaccinated or have a negative COVID-19 test.

  • Inpatients in our Christiana, Wilmington and Union hospitals may have one visitor daily between 10 a.m. and 8 p.m. The visitor must be 16 or older.
  • Patients having outpatient surgery may have one support person accompany them. Support persons must be 16 or older.
  • All visitors and surgical support people must show proof of vaccination OR a negative COVID-19 test within the prior 72 hours.

Holter Monitor

A Holter Monitor is a diagnostic test used to evaluate your heart rate and rhythm while you go about your normal daily activities.

Usually there are no special preparations for a Holter Monitor test.

What to expect during a Holter Monitor test

  • A nurse or technician will explain the entire procedure to you prior to the test. Do not hesitate to ask any questions you may have at this time.
  • Several adhesive patches, called electrodes, will be placed on your chest. These will be connected to a tape-recording monitor so that your heart rate and rhythm can be continuously recorded during the next 24 hours.
  • The monitor, called a Holter Monitor, will remain attached to you for the next 24 hours. Either a shoulder strap or a belt will be provided so you can carry the monitor conveniently. The Holter Monitor weighs approximately 1 pound.
  • While you are wearing the Holter Monitor, you will be asked to keep a diary of your activities and symptoms (i.e., palpitations, shortness of breath, chest pains, etc.).
  • You will then be asked to return the next day (approximately the same time), and the Holter Monitor will be removed. Your diary will be reviewed by the nurse or technician to be sure they understand you entries. You will then be allowed to leave.
  • Your Holter Monitor data will be scanned on a computer and reviewed and interpreted by a cardiologist. The cardiologist will submit a full written report to your personal physician. Your personal physician will then explain the results of the test and their implications to you.
