Introduction

  • When cardiac function is compromised it can lead to congestive heart failure or arrhythmia formation. 
  • In congestive heart failure the aim is to remove the congestion and improve cardiac performance, where possible. 
  • Drugs used for the management of congestive heart failure include: 
    • Diuretics 
    • Pimobendan. 
    • ACE inhibitors. 
    • Spironolactone. 
    • Other positive inotropes and vasodilators. 
  • Arrhythmias can come in multiple different forms and not all require treatment. 
  • Drugs used to manage ventricular tachycardias include: 
    • Lidocaine. 
    • Sotalol. 
    • Beta-blockers. 
  • Drugs used to manage supraventricular tachycardias include: 
    • Diltiazem. 
    • Sotalol. 
    • Beta-blockers. 
  • Management of bradyarrhythmias are rarely needed in cats, but occasionally medical or surgical (pacemaker implantation) management is indicated, but this depends on the underlying cause.
