Jenifer Bowles: Thank you! This was very helpful!
Jamie Taylor: Hi great videos straightforward with minimal technical babble, I am an ex
Combat Medic doing an eACLS course and have found your videos very
educational. Unfortunately although I do have knowledge of ECG's and
treatment of heart/circularly knowledge we combat medics have minimal
involvement with the use ant monitoring of ECG's and what pharmaceutical
intervention to give pre hospital as you are well aware in cases of TCPA
especially in combat situations the chance of survival is extremely low.
So getting my head around it by watching things like your videos really
helps. do you do one on ACLS in a pre hospital situation when you use meds
and electrical therapy to stabilise casualty's?
firemedic947: A 3rd degree block is best described as a "complete" block. There is no
"connection" or coordination between atrial contractions and ventricular
contractions. I don't know if "random firing" of P and QRS is really the
best way to categorize it. They are not "random" at all.
The p waves (atrial contractions) are uniform and evenly spaced - just like
they are supposed to be - at a rate of about 100/minute in your video.
However, the impulse never gets past the AV node. The ventricles are
"unaware" that the SA note fired and the atria contracted. There is
something wrong with the AV node or the bundle of HIS/perkinjes, causing
them not to conduct the impulse to the ventricles.
The "auto-excitability" of he ventricles then allows for them to initiate a
ventricular contraction on their own as a fail-safe. The QRS's are wide
(slow, indicating conduction thru muscle, not the conductive tissues), but
they are uniform and evenly spaced at about 40/minute - indicating the
contraction is initiating from roughly the same point in the ventricles.
Basically, you have 2 separate rhythms (atrial and ventricular) happening
at the same time. Occasionally, the P wave will be buried in the QRS. You
might be able to see it as a slight deformity in the otherwise uniform QRS
(you can see it at 12:00, where there is a small hump in the - wave that is
not there in a "normal" QRS), but not always.
Angela Bowman: I am an RN student. This was so helpful. Thank you.
Heather Owen: I'm in nursing school so I understand how valuable time is. Thanks so much
for taking the time to make this. Very helpful!
International .Gringo: Thank you sir. Good brush up for an upcoming final.
Susi Q: thank you SO much !!!
Becca Hampton: Wonderful! As both a medic and nurse, I really enjoyed your video.
dlovesrcdr: Great video! So very helpful in reviewing the different rhythms for my ACLS
Holly Daniels: This is the best video I've found on rhythms. Thank you so much! Very
clear and concise. Love it!
theredcliche: thank you! this video is great!
Kap Kaplar: Great video, if you can do more with additional rhythms would be welcomed.
Guadalupe Salazar: Quick question can a cardiologist diagnose long qt syndrome if he suspected
it would he tell his patient or send them to an ep
amaya2172000: awesome. thanks so much. from a new tele nurse.
Jodi Beydoun: There are a few fellow students of mine that are seriously struggling
through interpreting EKG. I have watched a few of your videos and feel
they will be a big help for them. Thanks for taking the time to make these
videos. Are you a med student?
danielle anderson: great video and explanation thank you so much!!
iyabo i: tnks, it helped alot.
Monique Gabule: Thanks!
Very useful indeed.
Love it... :-)
Silvia S: whats the name of the software you are using?
Lex: That clarified a lot! Thanks so much.
Can you please do one with the drugs corresponding to the associated
jeremy blackman: Great video's...any chance you could post something on st elevation and
anterior vs posterior mi's?
Vonda Miller: The videos are great! You are an excellent teacher! Thank you for making
these. Hope that you get making the videos. Good Luck with your career...
you will make a fine doctor. I used to be a registered nurse and appreciate
good learning material!
allison howard: Thank you very much for this helpful video. I have a better understanding
of the heart blocks.
Adaobi Ejinkeonye: Thanks! This is the most helpful video on EKG rhythms that I've seen so
far. Keep up the good work!
Renata Cimova: Hi, and thank you so much for taking the time out of your day to explain! I
am not a medical student, but I am someone who likes to learn a lot so I
self teach myself. Can you possibly explain the "normal" heart rhythms of
someone with Friedreich's Ataxia? What about Cardiomyopathy (dilated,
hypertrophic, and restrictive)? Thank you so much.
Ashley Zeitz: Great basic video for nursing students.
Rosalinda Perez: Thanks a million! You are a great medical student that takes time to
develop an online super video on this difficult topic. However, since I'd
been watching it, I'd feel more confident to take the test to pass the ACLS
Leo Aguillon: Can you please make more quizzes with more rhythms and possibly a study
guide with treatments?
Dawn Rogers: So thankful you took the time to do this!!!!!!!!!!!!Thanks.
Kabira Davis: can you go over how you calculated the bpm
Monique Gabule: Thanks!
Very useful indeed.
Love it... :-)
Crystals Jones: can you help me under stand my ekg? i wish i could post a pic but ill give
you some info...
Vent rate: 66 bpm
P Duration: 92ms
QRS: duration: 80 ms
PR interval:132 ms
QT interval: 386ms
QTc interval: 394 ms
QT dispersion: 30 ms
On the strip the qrus goes upside down, and at a point it all goes down to
one tiny block. and then it misses the p.. I am 21 year old female and am
going to a cardiologist on the 3rd. thanks ID apperciate the help in
understanding this.. im worried and want to know what the hell is going
on.. I want answer and the doc wont tell me.. I understand its hard to say
with out looking at the ekg.. but here is a link to in on yahoo answers..
gummywormz: thank you!
asheriko26: helped alot
jiyoung hwang: Thank you so much
Adriana O: thank you ! i was so lost at the beginning now im slowly getting it.
ronnike anderson: Wonderful video
Coco Delgado: Great help to learned the rhythms. Will appreciate if we can have a video
about cardiac cycle, blood flow, output....
ashley correll: Great job! Thank you so much.
stephanie pak: Awesome job! Thank you for this video! :)
mattie thompson: VERY GOOD VIDEO AND U DID A VERY JOB THANK U
Dr. Tarek Rafei: Thank you very much. I have really enjoyed watching this video.
Datis Azarpazhooh: Thank you very much
Lex Dang: That clarified a lot! Thanks so much. Can you please do one with the drugs
corresponding to the associated arrhythmia?
Dee: you da man.
Elena Escobal: I'm a registered nurse and I just found this app called ACLSMED super
helpful!! It has all ecg rhythms, clinical significance, causes,
treatments, etc. A must have for healthcare professionals and medical and
nursing students!!! It is available in androids and iphone. Just my two
Dee Jones: Great Job. Thanks
Raul Caballero: Great job breaking it down.... Thansk for taking the time
