Irregular Heart Rhythms in Dogs




Idioventricular rhythm does not have any standard treatment since it is a secondary disease. That is, it is secondary to another underlying condition, it does not exist as a solitary condition. The underlying condition will need to be treated, along with treatment that is done to alleviate the outward symptoms. The focus will be on increasing the heart rate and maintaining a stable rhythm. Medications may be prescribed for increasing the heart rate, or for blocking the vagal tone. If the medication therapy is not effective, a pacemaker implant may be used for maintaining the heartbeat and stabilizing the heart valves.


Living and Management


Your dog will need a lot of rest in order to recover properly. Cage rest is recommended in this case, since it can both give an animal a sense of security, and prevent the animal from overexerting itself. There is no need to alter your dog's diet plan, unless there is a specific health concern that would lead your veterinarian to make that recommendation. If the underlying cause cannot be diagnosed or treated, the prognosis for recovery is guarded to poor. One of the possible serious complications is congestive heart failure due to a prolonged state of bradycardia.
