Many experts initiate antiarrhythmic therapy once an arrhythmia, such as atrial fibrillation or ventricular tachycardia, is discovered. A soft heart murmur may be heard with a stethoscope, indicating turbulent blood flow within the heart. Secondary DCM can be caused by exposure to a toxin, deficiencies in certain nutrients (especially taurine), muscle diseases (such as muscular dystrophy), and certain infections. Caution should be used when introducing an antiarrhythmic drug with negative inotropic actions (such as beta-blockers) in a dog with a hypocontractile heart or in a dog with fluid retention (heart failure). In dogs with heart failure, furosemide (a diuretic) is given to remove fluid that has pooled in the lungs and elsewhere in a dog’s body.

In the case of ventricular tachycardia in boxers or Dobermans, commonly used antiarrhythmics include sotalol (2 mg/kg q12h), amiodarone (8-10 mg/kg q12h and reduce to 5 mg/kg q24h after 6 months; should be used with caution due to irreversible hepatoxicity), or a combination between mexiletine (5-8 mg/kg q8h) and a low dose atenolol.
