Heart monitoring service to assess an animal patient’s heart rhythm and rate

Holter Monitoring

Holter monitoring assesses an animal patient’s heart rhythm and rate. The Holter monitor is a portable electrocardiogram (ECG), which records the electrical activity of the heart continuously over 24 hours.

Your veterinarian may recommend a Holter monitor for several reasons

  • An arrhythmia is suspected
  • Your pet has had collapse or fainting episodes
  • To monitor a patient’s heart rate and rhythm while on certain medications
  • Your animal has unexplained dizziness, lethargy, or excessive panting
  • To monitor heart rhythms for animals with a pacemaker

Our Holter service provides

  • All necessary equipment and instructions for a 24-hour digital Holter monitor recording (including shipping)
  • A full report with recommendations from a WSU board-certified veterinary cardiologist
  • Discounts on recheck Holter monitors for long-term care
