Easy EKG: Interpreting Rhythms




What do you think about this video?

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.

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?

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. Thanks!!!!

Holly Daniels: This is the best video I've found on rhythms. Thank you so much! Very clear and concise. Love it!

dlovesrcdr: Great video! So very helpful in reviewing the different rhythms for my ACLS course.

Kap Kaplar: Great video, if you can do more with additional rhythms would be welcomed. 

theredcliche: thank you! this video is great!

Silvia S: whats the name of the software you are using?

jeremy blackman: Great video's...any chance you could post something on st elevation and anterior vs posterior mi's?

amaya2172000: awesome. thanks so much. from a new tele nurse.

Lex: That clarified a lot! Thanks so much. Can you please do one with the drugs corresponding to the associated arrhythmia?

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.

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

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 exam!!

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.

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!!

Kabira Davis: can you go over how you calculated the bpm

bote mi: tnks, it helped alot.

Monique Gabule: Thanks! Very useful indeed. Love it... :-) 

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 P-R-T: -5-69-45 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..

gummywormz: thank you! such knowledge!

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.... Thanks!!

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 cents! :)

Dee Jones: Great Job. Thanks

Raul Caballero: Great job breaking it down.... Thansk for taking the time

julieta12: Super helpful!!! Thanks sooooo very much

sliderulelover: There is an easier way to calculate the heart rate: 1. Count the number of large squares between successive R peaks. 2. Divide 300 by this number of squares. So for example using your streaming ECG, there are approximately 4.2 squares between successive R peaks. 300 divided by 4.2 = 71..4 beats per minute. This agrees with the 72 beats per minute shown.
