WPW / Wolff-Parkinson-White Syndrome: ECG / EKG findings, symptoms, pathology, & treatment

Understand WPW ECG findings, pathophysiology, symptoms, treatment options, common pitfalls, and more. WPW syndrome can cause life-threatening arrhythmias via accessory pathways in the heart. Learn the key EKG findings of Wolff Parkinson White pattern as well as treatment options for WPW.

This complete ECG/EKG interpretation course provides:

- 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
- WPW syndrome (Wolff-Parkinson-White) and WPW pattern.
- 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.

MedCram: Medical education topics explained clearly including: Respiratory lectures such as Asthma and COPD. Renal lectures on Acute Renal Failure and Adrenal Gland. Internal medicine videos on Oxygen Hemoglobin Dissociation Curve and Medical Acid Base. A growing library on critical care topics such as Shock, Diabetic Ketoacidosis (DKA), and Mechanical Ventilation. Cardiology videos on Hypertension, ECG / EKG Interpretation, 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 bundles and lectures have been particularly popular with RTs. NPs and PAs have given great feedback on Pneumonia Treatment and Liver Function Tests among many others. Many nursing students have found the Asthma and shock lectures very helpful.

Recommended Audience - medical professionals and medical students: including physicians, nurse practitioners, physician assistants, nurses, respiratory therapists, EMT and paramedics, and many others. Review and test prep for USMLE, MCAT, PANCE, NCLEX, NAPLEX, NBDE, RN, RT, MD, DO, PA, NP school and board examinations.

I am 34 years old and I was diagnosed during normal checkup. I never had speed heart beat or any visible symptoms. My cardiologist said after echo and egc that it appears to be by birth and no medication is needed until I have any symptoms in future. I have always been into sports and luckily I never had visible symptoms. I wish it doesn't increase much with age

[RashidaB]

I'm pretty sure that's THE best I've ever heard WPW explained in addition to its treatment effects. Thank you!

[MAKEITGROW]

I’m going through this experience right now.. omg

[Y-Hopper-Z]

Had an ablation done on me. WPW was gone but it came back, looks like round number 2 is coming.

[motheraiya]

I was recently diagnosed and I'm waiting for an appointment to decide what's going to be done. This has really helped me better understand what's going on.

[zaphood]

Thanks for a great explanation. I had my wpw ablated some years back by a a real professional team at the Sahlgrenska Hospital in Gothenburg, Sweden.

[jessibrown]

I was diagnosed in 2016 and got Ablation in January 2017. Never came back until recently I was joking and feel it twice in a week all while joking. I do workouts an hour or more but don't know if it's a good idea. But i believe exercise help the heart. My doctor told me I can exercise. I don't think this WPW will never get cured its just like a ticking time bomb. I feel like I can die at any time especially while doing workouts

[kurtsinger]

I’ve had WPW for 45 years and have yet to get catheter ablation. Standing on my head has been my go to in getting out of AF. I has 1 reset in 2007 when all techniques failed and was given Varapamil (I exhibit a very wide QRS). Thank you so much. I now understand
That in the event I can’t produce sufficient vagal response I know what drugs not to take
To avoid another DC cardio aversion.

[omartorress]

I had this when i was younger.. and this is the the first time in 18 years that i understand it! 2 thumbs up!

[BigSmelly]

i have it now and may be having surgery on Monday to remove the pathway had it since i was born and this would mark my second surgery.

[zhanglisa]

I have type A WPW syndrome. Meanwhile I also have mild pectus excavatum. Being a geneticist myself, I am very nervous to think about the possible linkage between these two defects. But I don’t want to perform any research on myself. I am very nervous about passing the genetic mutation to my offspring because it’s showing a dominant inheritance pattern in my family.

[nicebunsmagoo]

Nice job explaining WPW I have a much better understanding now. I have asymptomatic WPW which happened to be caught on a routing checkup with my primary care doctor. I have been told that I may never show symptoms as you stated, and at least one cardiologist said they would not consider ablation if I didn't have any symptoms. I just hope that one day I don't go from not having any symptoms to some catastrophic signaling event.

[ramonatrifoi]

Great explanation. I had cardiac ablation because of WPW and your video makes so much sense. it is also a great help in my preparation for CSCT exam.

[khizarhayat]

Great illustration. But i have one query can you tell me why is the qrs complex broad in an all accessory pathway?. Shouldn’t it be narrow as there is no nodal delay or you meant both av node and accessory pathway participate in generating the qrs at two different rates and refractory period so it gives an overall broad complex ?.

[adonsstorre]

Thanks for the video.I already undergone the Procedure in 2010. Thanks God, i never experience anymore palpitation.May I ask if there is possibility that i will experience again this palpitation? By the way I'm 50 yrs old now and I regularly do workouts and play ball games without any problem at all. Thank you.Hoping to hear from you

[thepalettewhispererasmr]

Best explanation of WPW I've seen

[grandstorm]

I've kind of recently been bumped back and forth between WPW Syndrome and Pattern by doctors, and all of them including cardiologists are throwing every type of beta blocker at me. Your video says beta blockers are actually very bad for wpw. So then are doctors trying to kill me? Should I be asking them for Procainamide instead?

[mealex]

I have this and was great to know more 👍

[angeldark]

Also, as someone who first encountered this in 2009, as a patient, the astounding amount of consumer friendly info available now is astounding and fantastic!
