久咳不癒是否感染了肺炎

Sinustachycardia with an increase in P duration which can indicate (especially in sucha small dog) an enlargement of the left atrium. The other measurements are within the reference values. IN a dog of this age, a valvular insufficiency is the most probable cause of the ECG abnormailities. As this is a small dog, some of the reference values may still be too high or too long, with which I want ot suggest that the abnormalities seen on ultrasound or radiography can be more outspoken than what is suspected just in the ECG alone.Seeing the history, physical exam results and Rx results, the animal can be classified as a heart patient I.S.A.C.H.C. (the veterinary classification system) class 2. This means that there are clinical signs at when exercised and there are abnormalities in the diagnostic work-up. It is even possible that the animal can be classisfied in class 3a (clearly problems at rest also but still a patient which can be treated at home with tablets).
Based on the ISACHC class 2/3a classification for this animal the following therapy would be warranted: ACE inhibitor absolutely. Furosemide or another diuretic should be added if there are signs of coughing, dyspnea or effusions/congestion. The tachcyardia should be attacked with digoxin. The therapy can be evaluated after 7-10 days. The overall picture of the animal is important, with the onwers’ remark on general well being of the animal. Furthermore, one should check the heart rate (should be decreased to 100-120/min. in the practice situation) and look for signs of congestion (hopefully not present or not present anymore). When the treatment is insufficientie, adaptations should be made.
