Summary: 12 leads = 12 views of the heart 10 electrodes used. 4 in limbs, 6 in the chest. Right leg is used as a ground (earth). The electrodes in three limbs form a triangle, which gives 6 views ( 3 Biploar views (Lead I, II, III) and 3 unipolar views (aVR, aVL, and aVF). Other 6 leads (views) are obtained from 6 electrodes placed in the chest region that give Horizontal Plane.
This video is nothing short of a masterpiece. To explain a difficult concept so easily truly shows how much of an expert you are. Thank you, Dr. Campbell.
You did what multiple professors and hundreds of other videos on here couldn’t do. This was all I was missing to understand the bigger picture. Thank you 🙏🏻
Such a NICE video! I finally got it! Took me ages to read and get this and understand so well. Its teacher's like you that make medicine a beautiful art! Much love from Canada!
Thank you very much for this, doctor! I wish my trainers were anything like as clear and succinct when explaining these concepts. I'm extremely grateful to you for producing such high quality content.
Fantastic Video! Video summary 10 electrodes are used 12 leads/ format Eidnoven Triangle Lead I,II,III are first Lead I= view from the top RA and LA Lead II= view from the right arm to left leg Lead III= view from left arm and left leg avr= right side view of heart avl= left side view of the heart avf= view from the foot foot= left leg the right leg is used as the ground earrth There is 6 chest lead also known as precordial lead v1 on the 4th intercostal space to the right of the sternum v2 on the 4th intercostal space to the left of the sternum v4 on the 5th intercoastal space left midcalvicular line V3 between the middle of v2 and v4 V5 placed at same level of v4 but at the axillary line V6 placed at level of V5 midaxillarly line The purpose of all these leads is to give us view of the heart from different angles which is important to detect possible heart problems
Honestly, I am a Nurse and Physical Therapist by professions. Passed my board exams both in my country and the US; but is only now that 12 lead ekg is clear to me. thank you sir! nice
Wow. I have struggled with this concept for two weeks and you explained it in 10 minutes where I perfectly understood it. Thank you so much for posting this video
Thank you! I'm in Paramedic school and we just started cardiology, our textbook only gives this about 2 paragraphs of explanation before jumping into rhythms. This video helped me to understand how and why the different leads work, rather than "here's how to put the electrodes on, now just look at Lead II mostly".
such type of simple and understandable language and method is badly required for indian students. thanks dr. john campbell. you really wants to share your knowledge with the world without any hiccough.
I really appreciated this video. Dr. Campbell explained my questions thoroughly, about why it’s called a 12 lead ecg, when you actually only place 10 leads on the patient. I LOVE learning about the heart, and this video did not disappoint! Thank you, Dr. Campbell.
I have watched a number of your videos to help me understand what they don't seem to be able to teach in class, you are amazing! I always understand what your saying and you make everything clear, thank you!
Dr. Campble, you are the best. I am an auditory learner first and foremost and a visual learner second, you present both beautifully, I thank you emensly, thank you, thank you.
Simply spectactular explanation there Dr, you are wonderful. I have been trying to understand this concept all day till bumped into your vid. Thank you ever so much, from the bottom of my heart. no pun intended.
Thank you for this. I haven't done the ACLS cause I worked for 5 years in the NICU and ECG skills were barely utilized in our department, if at all. But now I'm trying to transition to adult nursing so I really need to review these topics. This was really helpful, thanks.
Brilliant. This should be on the curriculum of any one taking the role of lead placement and what they do and the areas of the heart they read. Certainly helps me understand a bit more.
Thanks so much, I am working in a coronary care unit on clinical placement at present and ECGs are going to be the death of me..... this is a great simple explanation. Thanks again
Thank you so much for this video. I have read the beginning of that stupid orange EKG book so many times and it never made sense. After watching your video once I totally understand!
Phenomenal. I love the way that you explain the information. It really helps me to learn the information and to understand it too. Thank you very much for all of your amazing videos.
Thank You very much for The Best explanation!!!!! English is my second language, I speak Ukrainian and Russian. I finished EKG class. But I couldn’t get it completely. I did it . Than You Very Much.
wow!!!!.. very well done and easy to understand. The 10 minutes time is short, precise and to the point. .. Now if you could give me your brain, I will gladly take my exams ...THANKS ALOT.
Impressive video! You made it simple in a way that we can easily understand and yet its straightforward! I’ve been looking for this kind of video and this is so helpful. Thanks!
MashaAllah you teach incredibly! such a grasping soul. I honestly wish all professors would teach as thoroughly and as comprehensively as you do! you're brilliant! May Allah (swt) bless you and all your loved ones endlessly.
