Final answer:
The Doberman Pinscher requires immediate veterinary treatment for cardiac distress, which may involve antiarrhythmic medications, electrical cardioversion, and supportive care. Investigation into the underlying cause is necessary, including potential heartworm infection treatment.
Step-by-step explanation:
Treatment for Doberman Pinscher With Cardiac Distress
Based on the symptoms of weakness, cough, and lethargy, and given the ECG findings of wide complexes at a rate of 242 per minute but with a pulse rate of only 96 per minute, the Doberman Pinscher is likely experiencing a form of cardiac distress, possibly ventricular tachycardia with pulse deficit. This is a serious condition where not all of the heartbeats are resulting in effective pulse or perfusion and immediate veterinary treatment is crucial.
Treatment would typically involve stabilizing the dog's cardiovascular function. The disparity between the ECG rate and the actual pulse suggests a significant drop in cardiac output, which needs urgent correction. Intravenous access for the administration of antiarrhythmic medications or possibly electrical cardioversion may be required, depending on the severity of the condition and response to drugs. Supportive care, including oxygen therapy and close monitoring of vital signs, would also be part of the treatment plan. The underlying cause of the arrhythmia should be determined and addressed to prevent further recurrence.
In case of heartworm infection, as suggested by the reference to adult worms residing in the heart and leading to complications such as coughing and heart failure, specific anti-parasitic treatment would also be needed in addition to addressing the immediate cardiac issues.
