This is a PAST clinic study
Purpose of study
To investigate the effects of commonly used doses of theophylline on heart rate parameters. This information will help to establish dosing protocols for theophylline use in dogs with certain forms of abnormal heart rhythms (arrhythmias).
Benefits
Enrolled dogs will receive free cardiology exams, echocardiogram, diagnostic electrocardiogram (ECG), comprehensive lab work (serum chemistry, complete blood count, and urinalysis), and three continuous 48-hour Holter monitors (portable ECG).
Enrollment requirements
Eligible dogs must be physically healthy, between 1 and 6 years old, less than 65 pounds, and not currently receiving any medications.
Treatment methods
- Following a screening appointment, all dogs that are enrolled in the study will return for a total of three study appointments at the WSU Veterinary Teaching Hospital (VTH) that will span the course of four weeks.
- Each study appointment will consist of a brief drop-off appointment for a blood draw and placement of a 48-hour Holter monitor.
Owner responsibilities
- Transportation to and from the WSU Veterinary Teaching Hospital, including three additional trips to return Holter monitors.
- Giving medication in a timely manner and recording activity of your dog while wearing the Holter monitor.
