I'm a Nurse Educator, who teaches EKG interpretation classes, and this video was so helpful . You did such as awesome job in explaining paced rhythms. I look forward to viewing more of your videos. Awesome Job!!!
At 5:44 on the ventricular pacing there is no P wave. Does this mean that the heart is not generating an atrial depolarization on its own either? It seems that there should be a P wave without a pacer spiker immediately preceding it in ventricular pacing.
Im in my second semester of paramedics and starting to learn ekgs and I've been watching your videos non-stop and are very helpful. it looks like you havent posted in a while you should.
Thank you so much for the clear explanation. Can you please also do a detailed video about abnormal pacing ?example: oversensing/undersensing? failure to sense/capture?
thank you --- just one question, is there a difference between an intrinsic beat and a native beat?? my textbook seems to use these terms interchangeably!
Demand means that the Pacer will kick in whenever the set threshold is met. Meaning, if they set a threshold of 50 beats per minute, the demand pacemaker will kick in to maintain a rate of at least 50 bpm. Yes, a fixed pacemaker would be 100% paced.

Ventricular Rhythms Question: What is the defining feature of ventricular fibrillation on an EKG? A. Regular rhythm with wide QRS complexes B.

Amazing video. Excellent examples.

if courses like this existed on youtube for every aspect of medicine I would be delighted, kudos friend
Thank you for putting this together. I love your presentations. You're an awesome educator!

a thank you is never enough for these great videos..much appreciation for your efforts
You are awesome! Thankyou! I was struggling, but you explained the content very well. Much appreciated :)
Im in my second semester of paramedics and starting to learn ekgs and I've been watching your videos non-stop and are very helpful. it looks like you havent posted in a while you should.
This video cleared up anyquestions I had as far a Pacing thanks
This is such an excellent video!
great explanation of paced rhythms
Well done! This is the first of the series I have watched. Looking forward to checking out the others. Thank you!
Thanks for sharing 👍👍
Awesome information for a paramedic! I'll use what I learned here to help me care for patients.
These videos are great! Thanks
Wonderful!!!
Very well elaborated and explained. Thank you
Thank you so much for the clear explanation. Can you please also do a detailed video about abnormal pacing ?example: oversensing/undersensing? failure to sense/capture?
Great teaching!
Still trying to work out which one i have ?
beautiful
Very informative and easy to understand.
Glad it was helpful!
Excellent excellent execellent
My ilustrativo y asequible,just great!
thank you --- just one question, is there a difference between an intrinsic beat and a native beat?? my textbook seems to use these terms interchangeably!
I imagine it’s the same thing, as an intrinsic beat is native to the cells. I don’t use the native term though so I couldn’t say for sure.
Thank you so much
Hey, love these lessons! I was wondering, what software do you use to live draw and annotate your videos? Thanks!
This video was really helpful for me to understand pacing thanks
when you say demand, can you say thats like partially paced like lets say 50% paced?
when you say fixed, does that mean 100% paced?
Demand means that the Pacer will kick in whenever the set threshold is met. Meaning, if they set a threshold of 50 beats per minute, the demand pacemaker will kick in to maintain a rate of at least 50 bpm. Yes, a fixed pacemaker would be 100% paced.
Why are some pacer spikes above the line. And others below?
This would have to do with the vector you are viewing from

@Meducator01 thanku so much 💓 💖 💗
can you get STEMI's that are stemi's with atrially paced rhythms....i imagine unreliable with ventricular pacers?
Why is the r wave flipped?
Very helpful, many thx
you help me alot thanks
thank you sooooo much
My savior haha thank you!
Very informative
10000 thanks
Thak you for this video.
