Plain-English summary

A 3-month-old Boxer was brought to the vet after showing signs of a fast heartbeat and unusual heart rhythms. The vet used special heart monitoring techniques to diagnose a condition called preexcitation alternans, which can affect how the heart beats. This condition can lead to rapid heart rates, but with the right tests, the vet was able to understand how the dog's heart was functioning. Treatment options can vary, so it's important for pet owners to discuss the best approach with their veterinarian.

Abstract

Preexcitation alternans and orthodromic atrioventricular reciprocating tachycardia were diagnosed in a 3-month-old Boxer. The images described here show how conventional electrocardiographic techniques (12-lead surface electrocardiography, 24-hour Holter monitoring, and ladder diagram) can be interpreted to gain detailed information on presence of canine atrioventricular accessory pathways and their conduction properties.
