Decoding the Jargon: The Difference Between ECG and EKG Explained

Ther is no difference between the both or difference ecg ekg; ECG stands for electrocardiogram, and EKG stands for electrocardiogram. Both are used to run the same test. Considered a great ally for preventing and controlling heart disease, the ECG is one of the exams that help save lives every day. 

Therefore, in today’s article on cardiocare, you will learn more about the subject and check out a special tip about electrocardiograms in Salvador.

The Emergence Of The ECG

It is from the European continent that the first records of electrocardiograms come. Since the end of the 18th century, several scholars have been experimenting with electrical stimuli, which led to a faster growth of scientific alternatives to understand more about the cardiovascular system. Over time, the initial experiments with resources that required the volunteer to submerge parts of their body in saline solution evolved. In the following years, heart studies expanded and developed considerably.

In the same way, advances were made in reducing the costs and accessibility of exams. Proof of this is that almost three centuries after the emergence of pioneering scientific investigations, technology has evolved so much that it is now possible to perform ECG remotely through the resources offered by telemedicine.


First of all, just from what we’ve seen so far, we can see that the ECG is a very important test, right? With that in mind, we have 5 pieces of information you can’t help but check before taking your electrocardiogram.

Now you will see 4 essential points about performing the ECG and a special tip in the last item on the list.

  1. It is worth noting that the ECG test is a non-invasive procedure and does not cause any pain to the patient.
  2. The process is short since the completion time usually does not exceed 10 minutes.
  3. The ECG at rest is a test that does not require any special preparation; however, it is recommended that the patient does not practice physical activities for at least 20 minutes before performing the electrocardiogram.
  4. Be very careful when choosing a clinic for your exam. As we will see below, the ECG is considered a great ally for combating and preventing heart disease. Therefore, it is vital that your ECG results are reliable to be used correctly to assist in a diagnosis.
  5. At the end of this article, we have good news for anyone looking for an electrocardiogram in Salvador.

What Is An Electrocardiogram, And How Does It Work?

In summary, we can understand the ECG as a test that measures the heart’s electrical activity.

The resting ECG exam involves inserting electrodes into the patient’s legs, arms, and chest. Then, with the electrodes well positioned, the measurement begins. In this way, the electrocardiogram device produces traces that graphically represent the patient’s electrical activities during the exam.

Each trace refers to different information about the circulation of electrical impulses in the heart, so healthcare professionals must carefully analyze each detail to optimize the diagnosis.

Therefore, the ECG is capable of showing aspects such as:

– heart rate;

– frequency of beats;

– coronary changes;

– possible damage to the heart muscles;

– electrolyte abnormalities such as lack of sodium and potassium.

The heart’s electrical activity during exercise stress.
