If you’ve been to the doctor because of heart condition or you have a family history of heart disease, you may be asked to schedule a test called an EKG or ECG. Many people get nervous when they’re required to take medical tests, but it’s important to know that this test is not invasive and is life-saving.
EKG and ECG are abbreviations for the test called an electrocardiogram. This test measures the electrical activity of the heart. Whereas a stethoscope can allow a doctor to listen to the heart, the EKG lets the physician see the actual electrical wave of the heartbeat.
The heart actually beats in three types of waves. The first wave is the P wave. It occurs when the right and left atria beat. These are the upper chambers of the heart that receive blood from the body or the lungs.
The next wave is called the QRS complex and is made by the bottom chambers of the heart called ventricles. These are the parts of the heart that pump blood away from the heart. The final wave is called a T wave and it results in the recovery of the ventricles after they beat.
A doctor can understand a lot about the heart by looking at this pattern of waves. The EKG will show how long it takes electrical activity to pass through the heart. If it’s moving too fast or too slow, they can then begin to move closer to diagnosing your problem.
The test will also show if there are specific parts of the heart that are working inefficiently by measuring how much electrical activity is present in them. When you go to have this test, some stickers will be placed around your chest near the heart.
These will be connected to wires that are hooked to the EKG machine. While the test is running, the machine measures your electrical activity. Once the test is finished, the stickers are removed.
Removal of the stickers is the most uncomfortable part of the test. The rest is absolutely painless because the machine is not running any type of current into your body. It’s only measuring the electrical activity inside of you.
The EKG is one of the most common tests used to diagnose problems of the heart. When you have this test, the results may lead to a diagnosis or to further testing to pinpoint the exact problem. Tests like an echocardiogram may be ordered. The echocardiogram is an ultrasound of the heart and is also a painless and noninvasive way to assess heart wellness.
