ugh thank you thank you thank you! I just started in a CTSICU as an RN and temporary pacers have always scared me a little because I didn't fully understand them...this series helped a ton!
Hi, you are one of the best resources, and probably the best free one, I also really appreciate it you take the time to read all the comments and even respond
Wow, thank you so much Roger. That really means a lot to me. I'm happy to be able to help and I really enjoy interacting with everyone in the comments. It's getting harder to keep up with them all as the channel grows, but I'm going to try to keep up as long as I can!
I don't have any videos of using the actual device or setting it up. Given the different nature of different pieces of equipment, I've choose not to do practical hands on stuff like that and hope to lay a good foundation to help you understand that for whatever piece of equipment you use. :)
great video! I do have a question if you can help me understand, and please correct me if i am not interpreting this correctly: When the problem is failure to pace, no pacer spikes, the problem could be oversensing, so the sensitivity is high (mV low/ fence is low) so we have to increase the mV (aka bring the fence up) which will lower that sensitivity But when the problem is failure to sense, oversensing is when sensitivity is low (mV high/ fence is high) so we have to decrease the mV (bring the fence up) which will increase the sensitivity This is confusing for me because oversensing would have two contradicting definitions. Thank you!
Hello! Thank you for the video. I have a question: how come the spikes produced by the pacemaker when its failing to sense don't produce additional ventricular or atrial contractions following the hearts own beat if its not sensing it?
Hi! I believe it depends on where in the cardiac cycle the spike is fired- for example if the spike is delivered right after the qrs that means the ventricles just contracted- if the ventricles attempt to contract again- this is when r on t can occur sending the patient into vtach or vfib, so it can happen, and is very dangerous, that is why if you see inappropriate spikes you immediately begin to trouble shoot
Hi! thank you very much for your videos! If I may ask you a question, the ekg at 10:07 seems to be a ventricular paced rythm (wide QRS) just without the "spikes sign". When not paced, shouldn it be a sinusal rythm, with che classical pattern P-QRS-T waves? Thank you again for you time
Sorry I missed this for so long. So to answer your question, it really just depends what the patients rhythm is underlying. If they are a sinus rhythm (SB, etc) then yes. They could be junctional, or 3rd degree, or ventricular. Just depends.
