Is there cause for concern? The ECG shows a sinus rhythm with significant sinus arrhythmia. The heart rate increases with inspiration and decreases with expiration, which is called respiratory sinus arrhythmia. The QRS-axis is between 60 and 90 degrees, which is physiological at this age. The negative T-waves in V1-V3 (V4) are also age-appropriately normal. Therefore, there is no reason for concern; the ECG is considered normal for the child's age.</p> </div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div class="field-label">Rate this content:&nbsp;</div><div class="field-items"><div class="field-item even"><form class="fivestar-widget" action="/taxonomy/term/38/feed" method="post" id="fivestar-custom-widget" accept-charset="UTF-8"><div><div class="clearfix fivestar-average-text fivestar-average-stars fivestar-form-item fivestar-hearts"><div class="form-item form-type-fivestar form-item-vote"> <div class="form-item form-type-select form-item-vote"> <select id="edit-vote--2" name="vote" class="form-select"><option value="-">Select rating</option><option value="20">Give ECG OF A 3 YO BOY, IS IT NORMAL? 1/5</option><option value="40">Give ECG OF A 3 YO BOY, IS IT NORMAL? 2/5</option><option value="60">Give ECG OF A 3 YO BOY, IS IT NORMAL? 3/5</option><option value="80" selected="selected">Give ECG OF A 3 YO BOY, IS IT NORMAL? 4/5</option><option value="100">Give ECG OF A 3 YO BOY, IS IT NORMAL? 5/5</option></select> <div class="description"><div class="fivestar-summary fivestar-summary-average-count"><span class="average-rating">Average: <span >3.4</span></span> <span class="total-votes">(<span >5</span> votes)</span></div></div> </div> </div> </div><input class="fivestar-submit form-submit" type="submit" id="edit-fivestar-submit" name="op" value="Rate" /><input type="hidden" name="form_build_id" value="form-dMc_MoadP1Mz_KE_AFy0Fl7gu6InhXsdyiY0AkvKeEk" /> <input type="hidden" name="form_id" value="fivestar_custom_widget" /> </div></form></div></div></div><ul class="links inline"><li class="addtoany first last"><span><span class="a2a_kit a2a_target addtoany_list" id="da2a_1"> <a class="a2a_dd addtoany_share_save" href="https://www.addtoany.com/share#url=https%3A%2F%2Fwww.ecgguru.com%2Fblog%2Fecg-3-yo-boy-it-normal&amp;title=ECG%20%20OF%20A%203%20YO%20BOY%2C%20IS%20IT%20NORMAL%3F"><img src="/sites/all/modules/addtoany/images/share_save_256_24.png" width="256" height="24" alt="Share"/></a> </span> <script type="text/javascript"> <!--//--><![CDATA[//><!-- if(window.da2a)da2a.script_load(); //--><!]]> </script></span></li> </ul> Mon, 31 Jul 2023 10:17:32 +0000 Dr A Röschl 857 at https://www.ecgguru.com https://www.ecgguru.com/blog/ecg-3-yo-boy-it-normal#comments ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus Rhythm https://www.ecgguru.com/ecg/ecg-basics-accelerated-junctional-rhythm-overriding-normal-sinus-rhythm <div class="field field-name-field-ecg field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/ecg/ecg-basics-accelerated-junctional-rhythm-overriding-normal-sinus-rhythm"><img typeof="foaf:Image" src="https://www.ecgguru.com/sites/default/files/163%20Junct%20tach%20overriding%20NSR.jpg" width="1800" height="302" alt="" /></a></div></div></div><div class="field field-name-field-ecg-interpretation field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>This strip shows a junctional rhythm at a rate of 110 beats per minute. The QRS complexes are slightly wide at .10 seconds (100 ms), and they are within the parameters for supraventricular rhythm. The term, "junctional tachycardia" could be used, also, but this is not likely a "reentrant" junctional tachycardia, which would be fast, regular, and have a sudden onset. That type of junctional tachycardia is a PSVT. &nbsp; In this strip, we can see the underlying sinus rhythm in P waves that appear to pop up randomly. &nbsp;However, if you march out the P waves, you will find that they are regular, at a rate of about 90 per minute. &nbsp;The junctional rhythm has overrun the sinus rhythm. &nbsp;Most of the P waves cannot conduct due to where they have landed - in the refractory period of the QRS. &nbsp;The exception might be the P wave after the fifth QRS. &nbsp;The sixth QRS might be conducted from that P wave.</p><p>When accelerated junctional rhythm is encountered, you should suspect DIGITALIS TOXICITY - the classic dysrhythmia associated with digitalis toxicity is accelerated junctional rhythm. Other causes in adults could be beta-agonist drugs such as adrenalin, cardiac infection, ischemia, or surgery.<br />&nbsp;</p></div></div></div><div class="field field-name-field-rate-this-content

field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>This ECG is nearly completely normal. &nbsp;We say "nearly" because there are VERY subtle changes which may or may not be chronic. &nbsp;Unfortunately, we know nothing about this patient's history or circumstances except age, gender, and race, and the fact that she was an Emergency Department patient. &nbsp;If she presented with chest pain, the ECG might be viewed completely differently than if she presented with a fever.</p><p>So, first, let's look at what is within NORMAL range. &nbsp;Most of these characteristics will be readily seen by your BASIC LEVEL students. &nbsp;The rate and intervals are within normal ranges. &nbsp;The rhythm is normal sinus rhythm. &nbsp;There is good R wave progression in the precordial leads. &nbsp;That is, V1 is primarily negatively-deflected and V6 is positive, with Leads V2 through V5 gradually becoming more and more positive. &nbsp;The frontal plane axis is within normal range - Leads I and II are positive. &nbsp;This would be a suitable ECG to use when introducing beginning students to the 12-lead ECG.</p><p>As for what is NOT NORMAL, there are several subtle characteristics. &nbsp;First, the P waves are slightly tall and have a pointed appearance. &nbsp;The P wave in V1 is biphasic. &nbsp;This can represent P PULMONALE, a sign of right atrial strain. &nbsp;This is often seen with pulmonary disease. &nbsp;One might also expect to see a shift of the frontal plane axis to the right if there is right ventricular hypertrophy as a result of increased strain on the right heart, but here we see a subtle shift to the left. &nbsp;The axis is still within normal limits, but at 17 degrees, it is closer to the left than the right.</p><p>The ST segments here are not perfect. &nbsp;One could argue that there is VERY slight elevation in Leads I and aVL, and the shape of the ST in V1 is coved upward. &nbsp; Lead III's ST segment is flat, and the T wave is inverted. &nbsp;Without clinical corelation, it is impossible to determine the importance of these changes. &nbsp;It is a good discussion to have with your more advanced students.</p><p>As said, it would be MUCH easier to ascribe meaning to these changes if we knew something of the patient's chief complaint, symptoms, and history.</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div class="field-label">Rate this content:&nbsp;</div><div

include some good old "Normal Sinus Rhythm" strips from time to time. &nbsp;Teachers often have large collections of strange and unusual strips that their colleagues have saved for them. &nbsp;But, then they find themselves resorting to electronic rhythm generators for samples of "normal". &nbsp;Here is a strip from a healthy, 23-year-old woman showing NSR. &nbsp;The rate is 65 bpm, QRS duration 76 ms, PRI 136 ms, QTc 410. &nbsp;There are no abnormal ST segments or T wave changes. &nbsp;There are very slight rate changes from beat to beat, and the P waves appear to change morphology a bit. &nbsp;This can be due to the patient's breathing movements, and we would not delve too deeply into this in light of the fact that this is an ECG from an asymptomatic young ECG student. &nbsp;Absolute precision would come from an generator, but rarely from a human being. This is a good strip to teach rate and interval determination.</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div

an acute inferior wall M.I. &nbsp;The rhythm is normal sinus rhythm at 65 bpm. &nbsp;The QRS complex is slightly wide at 112 ms (.11 seconds). &nbsp;The patient did not have a bundle branch block pattern on his 12-lead ECG. &nbsp;The PR interval is .17 seconds, and the P waves are widened and have a "double peak". &nbsp;This can be a sign of left-sided heart failure, and is called P Mitrale. &nbsp;Your students should be advised not to try to diagnose acute M.I. from a monitor strip, as ST segments can be inaccurate on some types of monitors. &nbsp;However, any derangement of the ST segment on a monitor strip calls for an immediate 12-Lead ECG for confirmation.</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div
