When evaluating the heart rhythm on an ECG, using a stepwise approach simplifies the process.
- Count the heart rate and determine if it is normal or abnormal (bradycardia or tachycardia).
- Look at R-R regularity.
- Evaluate the shape or morphology of the QRS complex.
- Determine the degree of AV block.

What does an ECG measure Veterinary?
An ECG provides a very accurate way for your veterinarian to assess your dog’s heart rhythm. If his heart rhythm is abnormal, analysis of the ECG results can diagnose the exact arrhythmia that is present and suggest likely underlying causes for this arrhythmia.
How do vets calculate heart rate from ECG?
The average heart rate (ie, ventricular heart rate) can be determined on an ECG strip recorded at 50 mm/sec by counting the number of QRS complexes in 15 large boxes (75 mm) and multiplying by 40. FIGURE 1 P wave (P), QRS complex (QRS), and T wave (T). In this ECG, the average heart rate would be 120 bpm.
What does an ECG show on a dog?
An ECG allows an accurate determination of your dog’s heart rate. This can reveal whether his heart is beating at a normal pace, or whether it is beating too quickly or too slowly. An elevated or decreased heart rate can suggest specific medical issues that may warrant investigation. Is the heart rhythm normal?
How do you read ECG parameters?
Standard ECG paper allows an approximate estimation of the heart rate (HR) from an ECG recording. Each second of time is represented by 250 mm (5 large squares) along the horizontal axis. So if the number of large squares between each QRS complex is: 5 – the HR is 60 beats per minute.
How do I turn on my ECG machine?
Follow these steps to set up the ECG app:
- Open the Health app on your iPhone.
- Follow the onscreen steps. If you don’t see a prompt to set up, tap the Browse tab, then tap Heart > Electrocardiograms (ECG) > Set Up ECG App.
- After you complete set up, open the ECG app to take an ECG.
What is the procedure of ECG?
During an ECG, up to 12 sensors (electrodes) will be attached to your chest and limbs. The electrodes are sticky patches with wires that connect to a monitor. They record the electrical signals that make your heart beat. A computer records the information and displays it as waves on a monitor or on paper.
How do you calculate ECG speed?
When an ECG is run at a paper speed of 50 mm/sec each large box represents. 1 seconds and therefore counting 30 boxes or between 2 time marks is 3 seconds. By counting the number of complexes in 3 seconds and multiplying by 20 (3 x 20 = 60) you are able to calculate the number of beats per one minute.
How do you know if you have sinus rhythm?
If there is sinus rhythm, and the heart rate is less than 60 beats per minute, then sinus bradycardia is present. If there is sinus rhythm, and the heart rate is greater than 100 bpm, then sinus tachycardia is present. The links below take you to examples of each of these.
How do you calculate your heart rate with paper speed?
Heart rate: The standard paper speed is 25 mm (5 large squares)/sec. This means that if the interval between two beats (R-R) is 5 large squares, the HR is 60 beat/min. The HR may be counted by simply dividing 300 by the number of the large squares between two heart beats (R-R).
How long does an ECG take on a dog?
A typical electrocardiogram screening takes under two minutes to screen with the entire procedure, from start to finish, under ten minutes. Once the screening is complete, the EKG machine will print out a graph-like form for your veterinarian to interpret and report the results to you.
How much is an ECG for a dog?
Consultation and Examination: $150 for your pet’s first visit. Other recommendations such as, blood pressure, blood work, chest X-rays, electrocardiogram (ECG/EKG) or Holter monitor, will impact the cost of each visit. A typical cardiac work-up ranges from $725 to $1,100, with an average cost of about $900.
Do dogs need to be sedated for ECG?
The majority of animals do not need to be sedated or anesthetized for an echocardiogram. Dogs and cats getting an echocardiogram lie on a padded table with a cutout that allows the ultrasound probe to contact their chest wall.
What is the normal range of P wave in ECG?
P wave: 80 milliseconds. PR interval: 120-200 milliseconds. PR segment: 50-120 milliseconds. QRS complex: 80-100 milliseconds.
Can ECG detect heart blockage?
However, it does not show whether you have asymptomatic blockages in your heart arteries or predict your risk of a future heart attack. The resting ECG is different from a stress or exercise ECG or cardiac imaging test.
How much ECG is normal?
The normal range of the ECG differed between men and women: heart rate 49 to 100 bpm vs. 55 to 108 bpm, P wave duration 81 to 130 ms vs. 84 to 130 ms, PR interval 119 to 210 ms vs. 120 to 202 ms, QRS duration 74 to 110 ms vs.
