What to Expect From an EKG

Often abbreviated as EKG, an electrocardiogram is a test that measures the electrical activity of your heart through electrodes placed on your skin. An EKG shows how fast the heart is beating, the strength and timing of each beat, and whether the rhythm is steady or irregular. 

At WestMed Family Healthcare, we use this noninvasive test can help us detect various heart conditions.

What is an EKG?

Each time your heart beats, an electrical impulse travels through the heart. This electrical impulse triggers the heart muscle to contract and pump blood from the heart. The heart beats in a highly coordinated manner. Any irregularity in the heartbeat can indicate an underlying problem.

Looking at the pattern of the EKG provides health care professionals with information about the heart.

What to expect from an EKG    

Our techs apply a small amount of gel to your skin to help transmit electrical impulses to the EKG leads that are attached to your body. You lie flat and comfortable we attach leads to your skin by small suction cups. 

Typically, 10 electrodes are attached to the chest and sometimes the limbs. The test is painless and doesn’t cause any discomfort. The EKG machine doesn’t send electricity into your body and the entire test only takes about five minutes. 

We ask you to remain still during the test because moving can interfere with the results. You may breathe normally as you lie still. The electrodes record the impulses as your heartbeats. A computer records the impulses and displays them as waves.  

EKG results

Your doctor reads your EKG results and looks for abnormalities. Among the conditions an EKG can find are:

Heart rate problems

An ECG can help us identify a faster than normal or slower than normal heart rate.

Heart rhythm

An ECG can show heart rhythm irregularities. 

Heart attack

An ECG shows evidence of a previous heart attack or one in progress as it happens.

Inadequate blood supply to the heart

If you’re having symptoms like chest pain or tightness, an EKG can help us determine whether lack of blood flow is the cause. 

Structural abnormalities

An ECG can provide evidence of enlargement of the walls or chambers of your heart. 

If we find any abnormalities on your ECG, we may schedule you for additional tests.
