AV Nodal Reentry Tachycardia (AVNRT) on ECG / EKG

Atrioventricular nodal reentry tachycardia (AVNRT) is the most common type of supraventricular tachycardia. This is a selected video from Dr. Seheult's mini EKG / ECG course: www.medcram.com/courses/ekg-ec...
In this video, you will learn a systematic progression to spot AV node reentry tachycardia (AVNRT) as well as other key findings on ECG.
In this online ECG course, you'll learn the skills to confidently interpret EKGs and EKG rhythms in a systematic way, including:
- The physiology of the heart
- EKG leads and vectors
- Leads and EKG paper
- The ECG tracing
- EKG waves, complexes, and intervals (p waves, QRS complexes, PR interval etc.)
- Axis on EKG and precordial leads
- The autonomic nervous system and the heart
- Heart rate and automaticity on the ECG
- The R to R interval
- Rhythm, arrhythmias, and escape rhythms,
- Premature beats and pauses on EKG
- Bigeminy, trigeminy, and tachyarrhythmias
- V-tach and torsades de points
- Atrial and ventricular flutter
- Atrial fibrillation and ventricular fibrillation on ECG
- Heart blocks and escape rhythms (1st, 2nd, and 3rd degree heart block)
- Bundle branch blocks, hemiblocks, and fascicular blocks
- Hypertrophy (LVH) and atrial enlargement
- COPD, PE, Hyperkalemia, Digoxin and the EKG
- How to systematically read an EKG (and what a normal ECG looks like)
- Many practice EKG strips (that Dr. Seheult interprets step by step)
- EKG quizzes follow each video.
Dr. Seheult is famous for his ability to explain and illustrate key concepts with just enough detail so they are understood, not memorized... You won't become overburdened with too much EKG information too quickly.
Dr. Seheult will be your step by step mentor: reinforcing key cardiac physiology, explaining abnormal findings and how they develop in the first place, the appearance of a normal EKG, and a clinical perspective of EKG nuances, scenarios, and rare findings.

MedCram = More understanding in less time
Medical education topics explained clearly including: Respiratory lectures such as Asthma and COPD. Renal lectures on Acute Renal Failure, Urinalysis, and The Adrenal Gland. Internal medicine videos on Oxygen Hemoglobin Dissociation Curve / Oxyhemoglobin Curve and Medical Acid Base (approved for CME / CE). A growing library on critical care topics such as Shock, Diabetic Ketoacidosis (DKA), aortic stenosis, and Mechanical Ventilation. Cardiology videos on Hypertension, ECG / EKG Interpretation (Approved for CME / CE), and heart failure. VQ Mismatch and Hyponatremia lectures have been popular among medical students and physicians. The Pulmonary Function Tests (PFTs) videos and Ventilator-associated pneumonia lectures have been particularly popular with RTs. NPs and PAs have provided great feedback on Pneumonia Treatment and Liver Function Tests among many others. Mechanical ventilation for nursing and the emergency & critical care RN course is available at MedCram.com. Dr. Jacquet teaches our EFAST exam tutorial, lung sonography & bedside ultrasound courses. Many nursing students have found the Asthma and shock lectures very helpful.

You are not giving the key to diagnose the disease rather than general interpretation of the ECG, please take about the topic more e.g. : why the p wave is after QRS, why it's nigative what to lock for to diagnose AVNRT

[@Medcram]

Thanks for the comment. This video features a practice ECG only -- AVNRT is covered in detail in the ECG mini-course www.medcram.com/courses/ekg-ecg-interpretation-explained-clearly

[@stoyanmuhovski3186]

I am not quite sure about hypertrophy, because Sokolow criteria for hypertrophy is deeper S wave in V1 or V2 plus Tallest R wave in rather V5 or V6. So if we add Sv2 plus Rv5 it's definitely more than 35 mm

How successful are ablations for avnrt

[@hit2cupid]

What about ST segment in avR lead, doesn't it signify the MI caused by occlusion of left main.

[@samkitto010]

The way I try to diagnose avnrt is.
1- rate too fast for 2:1 flutter conduction. So from say >160ish bpm( more like 180)
2- is regular. So not RAF
3- signs of retrograde p wave in St segment.
4. Narrow qrs.
There is always other rare/odd stuff that can fit the same criterea. E.g Slow flutter with 1:1 conduction on a post ablation patient etc.

[@JT-fz3wk]

retrograde P is only in AVNRT slow-fast

[@nursep18]

this made no sense to me, the axis part
