How to determine tachycardia in a dog? - briefly
To determine tachycardia in a dog, first measure the heart rate by counting the number of beats per minute while listening with a stethoscope or feeling the pulse at the femoral artery. If the heart rate exceeds 100-160 beats per minute (depending on the breed and size), it may indicate tachycardia, especially if the dog is not stressed or exercising.
How to determine tachycardia in a dog? - in detail
To determine tachycardia in a dog, it is essential to follow a systematic approach that includes observing the dog's behavior, checking for physical signs, and measuring the heart rate accurately.
Firstly, observe the dog's behavior and general demeanor. Tachycardia can cause a dog to appear restless, anxious, or even lethargic in some cases. If the dog is panting excessively or appears to be in distress, these could be indicators of an elevated heart rate.
Next, check for physical signs that may suggest tachycardia. Feel the dog's pulse by placing your fingers on a major artery, such as the femoral artery located inside the hind leg near the groin area. If the pulse feels rapid and strong, this could indicate tachycardia. Additionally, examine the gums for color changes; pale or blue-tinged gums can sometimes be a sign of reduced blood flow associated with an abnormally high heart rate.
For a precise determination, measure the dog's heart rate using a stethoscope and a timer. Place the stethoscope on the left side of the dog's chest, just behind the elbow. Count the number of beats you hear in 15 seconds and then multiply by four to get the heart rate per minute. In dogs, a normal resting heart rate typically ranges from 60 to 120 beats per minute (bpm). If the heart rate is consistently above 140 bpm, tachycardia may be present.
It's crucial to remember that various factors can influence a dog's heart rate, including exercise, stress, and underlying health conditions. Therefore, it's advisable to measure the heart rate when the dog is calm and at rest. If you suspect tachycardia based on your observations and measurements, consult a veterinarian immediately for a thorough evaluation and appropriate treatment.
