Heart Block (First-Degree) in Dogs




Depending on the underlying disease causing the atrioventricular block, treatment will vary.


Living and Management


Your veterinarian will prescribe diet guidelines as necessary to treat the underlying cause of the disease. You will need to follow-up with your veterinarian for regular appointments so that any changes can be addressed immediately. EKGs will be taken at each visit to follow the progress of the heart's ability to conduct properly.
