It comes from a pacemaker patient whose pacemaker was briefly switched to VVI at 30 bpm due to a stimulation threshold test. The first 3 beats show a sinus rhythm with a frequency of approx. 40 bpm. This is followed by a premature ventricular contraction (PVC). The P wave of the next sinus node beat lands exactly on the T of the PVC. This cannot be conducted to the ventricles, either because the ventricular myocardium is still unexcitable or the PVC has conducted retrogradely into the AV node and this is therefore still refractory.</p></div></div></div> Mon, 20 Nov 2023 09:40:39 +0000 Dr A Röschl 881 at https://www.ecgguru.com Jason's Blog: ECG Challenge of the Week for March 31st - April 7th. https://www.ecgguru.com/blog/jasons-blog-ecg-challenge-week-march-31st-april-7th <div class="field field-name-field-blog-image field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/blog/jasons-blog-ecg-challenge-week-march-31st-april-7th"><img typeof="foaf:Image" src="https://www.ecgguru.com/sites/default/files/ECG%20of%20the%20Week%202l%20ladder.png" width="765" height="499" alt="" /></a></div></div></div><div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><p><span style="text-decoration: underline;"><strong>Patient's clinical data:</strong></span>&nbsp;
