Meet the top 10 most common arrhythmias in veterinary patients
At CVC San Diego, Whit Church, DVM, DACVIM (cardiology), a veterinary cardiologist at Desert Veterinary Medical Specialists in Gilbert, Arizona, delivered a quick list of the top 10 causes of arrhythmias you’ll see during an electrocardiographic examination. Church’s advice: Post this list by your ECG machine, and you’ll be whittling away your rule-outs in no time flat—and avoiding the flatlining, of course.
First, Church says you can cut the top 10 in half based on the patient’s heart rate. If the rate is < 70 beats/minute, you know you’re dealing with a bradyarrhythmia. If the heart rate is above 160 to 180 beats/minute, look to the top 5 tachyarrhythmia rule-outs.
With no further ado, here are the top 10:
1. Sinus bradycardia
2. Atrioventricular block
3. Sick sinus syndrome
4. Atrial standstill
5. Persistent atrial standstill
1. Sinus tachycardia
2. Ventricular tachycardia
3. Supraventricular/atrial tachyarrhythmia
4. Atrial fibrillation
5. Atrial flutter
Another bonus on the tachyarrhythmia list is that atrial flutter is uncommon, says Church, so you usually have only four conditions to consider.
