A regular heart rhythm has all of the aspects previously discussed. Drawings of ECG leads must be horizontal and do not touch each other. One of the most important components of interpreting an ECG is understanding the normal intervals and what they represent. In this post, we’re going to learn all about heart rhythms, so the next time you do an electrocardiogram (EKG/ECG), you’ll know what’s going on. These include Long QT or Short QT, in which the electrical pulse to the heart producing its rhythm is either too short or too long. QTc is the measure of time between ventricular depolarization and ventricular polarization. Search for an EKG strip from a simple drop down list. However, as you can see, the QRS complex is still prominent and visible. It may indicate atrial fibrillation, which is a condition where the heart becomes overstimulated and can speed up to 150 BPM or faster for brief periods of time. The location of the infarct determines what treatment should be used to improve oxygenation to the heart to minimize damage. Read the EKG strip 1. View the EKG strip in six-second segments and count the number of spikes that occurred. This is usually a 10-second recording from lead II. BMJ ECG Interpretation series: “ABC of clinical electrocardiography” February – June 2002 (15 articles + one errata) – A concise and easy to read series, which covers basic ECG interpretation, ischaemia and acute MI, broad complex tachycardias, atrial arrhythmias, extra-cardiac conditions (e.g. There is a problem of ventricular depolarization. EKGs can be used to diagnose heart attacks, heart problems including electrical malfunctioning and other heart problems. ECG paper (Figure 1) is helpful in understanding this as it’s organized and scaled to illustrate to those normal intervals. Each small square is one millimeter and is equivalent to 0.04 seconds. These signal components are called P, Q, R, S, T and U. The EKG is a printed capture of a brief moment in time. How to Read an ECG Strip ECG paper is a grid where time is measured along the horizontal axis. Basic ECG Interpretation. The difference you will see in the ECG strip is instead of the flat quiver for the P-wave , you see something that is referred to as Saw Tooth. What does it mean if the P-wave dips instead of making a slight rise? 30 large squares on an ECG trace represents exactly 6 seconds. Approved. The large squares measure 5 mm across and represent 0.2 seconds. First, the standard 12-lead ECG is a 10-second strip. ECG Rhythm The best way to assess the ECG rhythm is by inspecting the rhythm strip. This amount of time should be pretty consistent across the entire strip. Here are seven tips to help you gain confidence in interpreting what you see. ", "The 300/number of large boxes between two identical spike is very useful and simple. In addition, the six second rule is great for counting heart rhythms that aren’t regular like, atrial fibrillation, atrial flutter, sinus arrhythmia, sinus rhythm with PVCs etc. This post can also come in handy if you plan to work on a nursing floor with telemetry, or if you plan on taking advanced cardiac life support (ACLS), as you will need to be familiar with heart rhythms. Multiply that number by a factor of 10 to figure out the number of times your heart beats each minute. You can apply the 6-stage approach to help you interpret ECG rhythm strips. Junctional Rhythm. Thanks to all authors for creating a page that has been read 472,385 times. Looking at a sheet of paper with a tracing on it does not provide enough information.

The PR interval on an ECG should measure 0.12 to 0.20 seconds, covering 3 to 5 small boxes on the ECG. Select each heading to find out more. Note that this amount of time should be relatively consistent across the entire strip. Nurses are usually the first ones to read that “hot off the press” EKG tracing. Heart rate , heart rhythm , electrical heart axis , the pr interval , repolarization . I also really like websites that let you practice rhythm strips and EKG interpretation for free like PracticalClinicalSkills.com. In order to read the ECG correctly the speed of the tracing must be set to 25mm/s and the gain set to 10mm/mv Dawn Gray, RN has been a nurse since 1987 and has spent the majority of her career in critical care and emergency department settings. Keep in mind that some irregularities may show up on the EKG, but they may be considered normal if you do not have any symptoms, such as dizziness or lightheadedness. By looking at the waveforms on the EKG graph you look for the P wave followed by the QRS wave and T wave in that specific order. This must come first! Don’t sweat all the complex details when you are first beginning to read and interpret EKGs.

You can then see the time between your heartbeats, which should be .12-.20 seconds, in 3-5 small horizontal boxes. What does a long straight line between the T and P wave mean on an EKG? Rate is usually determined by which electrical circuit is “conducting” the heart. recommends the use of an ECG rhythm strip for diagnosis of AF: ‘By accepted convention, an AF episode lasting at least 30 seconds is diagnostic.’ 1 Kardia’s lead I rhythm strip will be of at least 30 seconds duration (longer settings can be selected) so it is sufficient to diagnose AF. The app reads ECG only on specially marked ECG paper. It may mean there is a delayed depolarization of the electrical conduction of the heart. The next method is using the rate determination chart. This article was medically reviewed by Sarah Gehrke, RN, MS. Sarah Gehrke is a Registered Nurse and Licensed Massage Therapist in Texas. If you counted 4 big boxes between peaks, you have a heart rate of 75 beats per minute (300/4) = 75. Abnormalities: right bundle branch blocks • Indicates conduction problems in the right side of the heartthe heart • May be normal in healthy people • R wave in V1, ie two R waves in Vin V1 Atrial fibrillation is present when an irregular heartbeat occurs when the P waves are non-existent and replaced by a squiggly line. This test can help determine the cause of symptoms you might be having or check the overall health of your heart.
