Symptoms of Heartbeat Arrhythmia in Cats

Dog Breeds

A heartbeat arrhythmia in cats occurs when the heart experiences abnormal electrical activity. The disturbance in electrical activity causes an irregular heartbeat, or a heartbeat that is too fast or too slow. The causes of heartbeat arrhythmia can include: inherited defects within the heart, infections, injuries, ingestion of poisons or toxins, or other underlying diseases.

Introduction

A cardiac arrhythmia is an abnormal heart rhythm caused by some disruption or irregularity in the heart’s electrical activity. Some cats live a healthy life with heartbeat arrhythmias, while others are affected more severely.

Symptoms of Heartbeat Arrhythmia

Cardiac arrhythmias can occur in cats of either sex and in all ages and breeds. Many owners are unaware that their cat has an arrhythmia until it is identified incidentally during a routine physical examination. When clinical signs do appear, they frequently are nonspecific and varied. The owner may notice that the cat is less active than usual, is intolerant of exercise or just tires easily. Severe arrhythmias can lead to coughing, fainting spells, abdominal distention and discomfort, difficulty breathing, weakness, fatigue, collapse and sudden death. It is not unusual for some combination of these signs to appear suddenly and then disappear just as rapidly, often not reappearing for weeks to months. These signs are not exactly signs of arrhythmias, but of heart disease.

If you notice any of these signs or patterns in your cat, it is important that visit with your veterinarian as soon as possible. Heartbeat arrhythmias can often be managed through medication and lifestyle changes, but the cause of the arrhythmia is not always easy to diagnose.
