An electrocardiogram (EKG or ECG) is a test that records the electric activity of your heart. This test can assist determine the cause of symptoms yous might be having or cheque the overall health of your heart. Reading a basic EKG is not that difficult. Notwithstanding, yous should always let your doctor or medical professional properly read your EKG and diagnose y'all.

1. one

   Understand the grids of an EKG paper printout. Voltage—the electrical signals of the heart—is measured along the vertical axis; time is measured forth the horizontal axis in squares. There are large squares that are divided into smaller squares.^[i]

   • Small squares are 1 mm beyond and represent 0.04 seconds. The big squares mensurate five mm across and stand for 0.2 seconds.
   • ten mm in height is equal to 1mV in voltage.
   • Interpreting these values volition help you lot make up one's mind if the heartbeat is irregular, or too fast or too slow.^[2]

2. ii

   Find the QRS circuitous and label it on the handout. The Q wave is the downward or negative dip right before the big spike. The R moving ridge is correct after that, and is normally the largest spike on the readout. Following that is the S wave, which is the dip down beneath the baseline again.^[3] Label all of these parts on the printout.

   • Expect at the peaks on the printout. You will need to look at the whole strip to check for an irregular heartbeat.
   • This is a pattern called normal sinus rhythm, and it's the basic EKG of a healthy heart. Many people'south EKG may vary slightly from this baseline, though, while all the same being completely healthy.

   Assess your P-waves. Find the P-waves on your EKG. P-waves are the smaller spikes right earlier the larger fasten (the R wave). They should be at the approximately same duration, direction, and shape through the entire EKG.^[four]

   • If they are non present, encounter if there any movement to the line at all, like a flutter, sawtooth lines, or a flat line.
   • P-might just be a small ascent, or bump, on the graph. They will not exist as sharp or as loftier as the QRS complex.

1. i

   Measure the time between your heartbeats. Locate the showtime of the P moving ridge and the showtime of the QRS complex. This is called the PR interval. Normal duration is between 0.12 to 0.twenty seconds, which is three to v small-scale horizontal boxes.^[5]

   • This amount of fourth dimension should exist pretty consequent across the entire strip. If there is a varied corporeality of time (boxes) between beats, it can point an irregular heartbeat. This is only something to worry about if your physician says then. Information technology can be completely harmless.

2. 2

   Assess your eye rhythm. Y'all may have a regular or irregular heart rhythm. If your rhythm is irregular, information technology may exist regularly or irregularly. To determine the rhythm, check if the intervals are the same length. Mark a few of your R-R intervals on a separate sheet of paper. Utilize that sheet of paper to move forth the rhythm strip to encounter if the intervals are nevertheless lengths.^[vi]

   • A regularly irregular rhythm has a design to the irregular rhythm. An irregularly irregular rhythm has no blueprint at all and is all over the place.

3. 3

   Calculate your centre rate if the heart charge per unit is regular. You tin can use the post-obit formula to calculate your middle rate. Count the number of squares between the 2 peaks (the R waves). Take 300 and divide it past the number of boxes between the ii peaks. In this diagram, it'south 3 boxes, so 300 divided by 3 = 100 BPM.^[7]

   • If y'all counted 4 big boxes betwixt peaks, you take a centre rate of 75 beats per minute (300/four) = 75.
   • This is only used for regular heart beats.

4. four

   Calculate your centre rate if the heart charge per unit is irregular. If the peaks aren't regular and there are dissimilar amounts of boxes between them, the heartbeat is irregular. Count the number of spikes that are in a 6-second readout and multiply the number past 10 to get an approximate charge per unit. For case, if there are 7 R waves in a six second strip, the heart rate is seventy (7x10=lxx).^[8]

   • Alternately, you can count the complexes on the rhythm strip, which represents 10 seconds. Multiply that number by half-dozen to notice the lx 2nd heart rate.

5. v

   Ask your dr. about whatsoever irregularities. Though anybody's normal EKG readout can vary, there are some irregularities that your doctor may investigate further. Your doctor will look at your EKG results, combined with your symptoms, and start to form a diagnosis.^[ix]

   • If the interval between the P and the R is too long, this is called a first degree block. A packet co-operative block is when the QRS interval takes longer than 0.12 seconds. Atrial fibrillation is present when an irregular heartbeat occurs when the P waves are not-existent and replaced by a squiggly line.
   • Continue in listen that some irregularities may show up on the EKG, but they may be considered normal if you practice not have any symptoms, such as dizziness or lightheadedness.

6. six

   Avert diagnosing yourself. Reading an EKG accurately takes a lot of knowledge and practice. While yous tin learn how to read your EKG and notice any irregularities, you should never try to diagnose yourself based on the EKG. Instead, yous should let your doctor or medical professional person diagnose you.^[10]

   • Fifty-fifty if you call back your EKG is showing irregularities, this does not necessarily mean something is wrong. Anybody has their own unique heart signature.
   • If you are worried near something on your readout, talk to your doctor and get them to explain it to you lot.

Article Summary X

To read an EKG, start by finding the voltage, which are the electric signals of the centre and are measured forth the vertical axis. Additionally, identify the squares that measure fourth dimension along the horizontal axis. You can then see the fourth dimension between your heartbeats, which should be .12-.twenty seconds, in 3-5 small horizontal boxes. Notation that this amount of fourth dimension should be relatively consistent across the entire strip. If you notice a varied amount of time or boxes between beats, it tin can indicate an irregular heartbeat. For more tips from our Medical reviewer, including how to talk to your doc most your EKG readout, keep reading!
