Instructions
Assess the situation and determine whether obvious treatments can be applied. For example, if your pet has a fever, rapid heartbeat will typically increase. Likewise, the heart rate can also increase due to shock for any reason. For either situation, undergo the normal method of treatment to subsequently reduce the heart rate.
Assume that the cat is suffering from a lack of oxygen due to an increase in stress in the event situational treatments fail to slow the cat's heart rate. Place the cat in a small space where activity is prohibited such as a small enclosed room, a cat carrier or simply hold the cat in a warm blanket, removing all opportunity for movement without disturbing airflow. This prevents your cat from performing excessive activity and offers him an opportunity to regain a normal heart rate.
Consult with a veterinarian to determine the best medication for your cat. In extreme situations where the cat suffers from a medical condition, known as feline tachyarrhythmia, as a result of a rapid heart rate, medication is often recommended. For example, beta blockers such as propanolol and atenolol can regulate muscle cell activities in a cat that cause rapid heartbeat. Other drugs may be prescribed depending on your cat's condition.
