Dog Irregular Heartbeat or Arrhythmia: What It May Mean and How Imaging Can Help
4 Paws Imaging Centers provides advanced diagnostic imaging — including echocardiograms, ECGs, and Holter monitoring — to help your veterinarian understand what is happening with your pet’s heart. We do not provide primary or emergency treatment; our role is to deliver the diagnostic imaging your vet needs to guide your pet’s care.
Common Causes of an Irregular Heartbeat
An irregular, too-fast, or too-slow heartbeat noticed by your veterinarian can come from several underlying issues, and pinpointing the exact rhythm problem usually requires imaging.
- Structural heart disease
- Electrical conduction abnormalities
- Underlying illness affecting the heart (thyroid disease, electrolyte imbalances)
- Age-related changes to the heart's electrical system
- Stress-related or intermittent rhythm changes
How Cardiac Imaging Helps Diagnose This
Because arrhythmias can be brief or come and go, we offer both snapshot and extended monitoring to catch what a single exam might miss.
- ECG for a real-time reading of the heart's electrical activity
- Holter monitor to record the heartbeat continuously over 24+ hours during normal daily activity
- Echocardiogram to check for structural causes
What Happens Next
Your dog's veterinarian will review the recorded rhythm data to determine whether medication or further monitoring is needed.
If your veterinarian has recommended imaging, or you would like to ask about scheduling, contact 4 Paws Imaging Centers at (630) 746-1382. We see patients by appointment only and work closely with your primary veterinarian to coordinate care.
