https://www.vetsurgeon.org/f/clinical-questions/25210/ecg-teaser Am I looking at premature supraventricular complexes and a wandering pacemaker? I&#39;ve defaced the ECG with some colour to try to make any chat that follows hopefully easier and only posted a third or the 5min trace ran. Thanks in advance! en-USTelligent Community 10https://www.vetsurgeon.org/thread/170821?ContentTypeID=1Mon, 19 Dec 2016 10:37:20 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:549c90d7-40c1-4b33-a2b9-f9e5a83581afMartin Atkinson<p>[quote user=&quot;Beats&quot;]what is accrochage?[/quote]It is where there is no relationship between the P wave and ventricular complex in atrio-ventricular dissociation and the P wave can get hidden in the QRS complex, then actually appear after the QRS and may be mistaken for an S wave.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/170795?ContentTypeID=1Sun, 18 Dec 2016 19:32:19 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:7c5aecc7-ea0a-4563-a56c-5a11c9142dfbBeats<p>thanks for sharing your thoughts, Martin.</p> <p>what is accrochage? i did google but without reaching a clear and unambiguous answer!</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/170747?ContentTypeID=1Sat, 17 Dec 2016 22:24:54 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:f8f27a18-4abb-4995-ae74-111d9e54fd0aMartin Atkinson<p>Interesting. I need to sit down with a cardiology text book for this but it looks like ectopic P waves with a degree of acrochage to me but what is interesting is that not every -ve P wave results in a premature ventricular complex. Whatever it is almost certainly secondary to cardiac failure so I would be looking to confirm and treat that. I&#39;ll be back if I have any better thoughts but it is Saturday night and the Islay Malts are beckoning!</p><div style="clear:both;"></div>
