Sinus rhythm, bradycardia and tachycardia 

I was 28 year old when finally a doctor realized that I have tachycardia and my hearbeat is over 115 when I am sitting. Till then doctors who saw that only said that oh I must be nervous because I am at a doctor or I have to loose weight and I only got shamed, but never treated. Since That one doctor gave me medicine I was finally be able to loose weight because I was able to be more active without my heart jumping out of my chest but even if I lost weight I still have this problem without the medicine and we found out my dad was also having heart issues. So dear to be doctors is you see a bigger person with a problem, don't shame them, please help them...

Especially important to know how to interpret ECGs when you aim to simulate cardiac function with computational modelling. Thank you, doctor!

Great channel . Thank you sir for your lesson . From iraq we thank you My allah protect you and your family and give you happiness .

Hi doctor thank you I'm a paramedic and this was very helpful!

I am a zoology student from Pakistan. Your videos are very helpful Dr. John. Keep up your good work Sir.

Thanks Dr. John. That's very informative

This lecture is great. For a better understanding, you can watch Dr. Najeeb's lecture from his RU-vid channel, and his premium lectures are also available on his website. He has explained everything about Cardiac Arrhythmias | Atrial and ventricular | Tachycardia and bradycardia and it's beneficial for me to understand the whole concept.

Dr. Campbell, I am a nursing student from USA, AZ. I love your videos! Your calming and confident voice gives me the strength to conquer this material late at night! :)

Thank you doctor. Have a nice day

Thank you and Much Love from the Philippines.

Good content, very much appreciated.

Nice Innovative teaching...

Aula Excepcional, Very good, Thansk you doctor

При 130/50 и пульсе 70 давление будет 105,79мм рт ст. При таких показателях давление будет высокое. При 130/50 и пульсе 37, давление будет 31,41мм рт ст. При таких показателях давление будет критически низким. При показателях 130/50 и пульсе 145, давление будет 214,89мм рт ст. Давление очень высокое. Подобное давление можно наблюдать при беге на 20км в 45°С жару, в теплой одежде с утяжелением.

Amazing!! Thank you sir. I finally understood!! 😊

Plus your talking about blood pressure and heart disease and anemia . Weakness , fatigue , anxiety , panic attacks , overthinking, etc .

I'm Iraqi doctor,thanks a lot sir,i hope to see more lessons plz

Your voice is so calming wish you was my GP i have been recently diagnosed with tachycardia have been given 40mg propranolol to take 3 times a day however propranolol isn't working so they would like to try Ivabradine.

Very good video!

@Dr. John Campbell Hello Dr. Campbell, I'm having trouble finding your books since the description links don't seem to work for me. Are these texts available elsewhere? I'm an ER Technician and I will be working tele, would like to be top notch in my EKG interpretation.

Thanks doc!

Ive had an ablation for SVT in 1999. I get tachycardia still, sinus. Panic attacks can do it and can cause chest pressure in neck left upper chest

If I remember correctly, the cutoff for bradycardia is 30 bpms. Anything lower than that is an agonal rhythm.

i watched this because my heart rate is over 100 and im still young. :(

Thanks

The ERC guidelines from the year 2015 states we shouldn't be injecting Atropin in Bradycardia. Why is that ?

Wonderful..

For most of my adult life I've cycled a lot, so been pretty fit. My resting HR was always below 60bpm, and during the night it would drop to 45!

I have 50-58 bmp while resting and my blood pressure is usually 110/70. My echocardiogram and blood analysis are perfectly fine. I feel well and not sure about the cause of my bradycardia. Can bradycardia be natural,like,without any causes?

My home kardia EKG said I'm in tachycardia. I take 100 mg potassium each day. I popped 200 mg extra and I got normal sinus rythum. Did that for a few days. Now I 've did continued all I and I want the brain stem to start controlling the heart rythmn.

Is this the same patient you’re demonstrating? Or different bpm?

Damn..... I got tachycardia with only 22y.o and holter results more than 75% of it sinus tachycardia. Light headed i thought was normal from lack of sleep. Only after dengue shock with ekg 140 bpm then i gone to a cardiologist. Thanks for the simple explanation.

I have sinus bradycardia. 6ft3 250 lbs. Definitely not an athlete. My hr when laying in bed usually goes to 45 beats per minute but when im up its around 75 resting. Ive seen 3 cardiologist and all have said im fine. I am on 20mg of lisinopril and 10mg of lexapro for anxiety and stress. Do those meds interfere with heart rate?

Thanks for such an elaborate demonstration.

My bpm is 53-57 while at rest and I’m 18 years old but I don’t feel like fainting nor any symptoms at all but I’m worried because it wasn’t like that before I had a couple panic attacks from weed. I feel like if I’m worried, I should go get it checked right? Edit. I’m pretty athletic I’m 145 lean, 5’11 and I workout. I’m a fast worker that I almost always sweat.

My walking average is 120bpm and my resting rate is at 70-75bpm i was diagnosed at the hospital with tachycardia but all my labs, X-rays, and ekg came back fine. They even preformed an echo and couldn’t find nothing. I am out of shape I’m 5’6 200lbs but I have no chest pains or shortness of breath I do have anxiety and my blood pressure was at 125/93 I’m going to see a cardiologist on the 23rd hopefully it’s nothing serious.

I have tachycardia whenever I go upstairs, (14 steps in my house) I have to take a rest after I’m up for like 2 minutes. I’m not overweight and I’m not underweight, I’m around 120 pounds in 8th grade, I’m not sure if that’s really bad or not. Dont know if I should go to the doctors again or not.

I have bradycardia. I’m 72 and play Pickleball 4 times a week. I go to a heart doctor also. I watch my heart rate while playing and it goes from 70 to 135. I come home and I fall asleep when I go home . I don’t think I’ll ever get better. I’m good for one activity a day . Any cure in the future or is it just going to get slowly worse?

دخيل ربك😍

What causes sleep induced tachycardia,

High potassium can also cause bradycardia.

If you ever get tachycardia are you going to have it for the rest of your life? I was on a medication for ADD called Elvanse and i had a bpm of 120-140 for a few days. I got very scared because i had a panic attack when feeling how hard and fast my heart was beating, i have been on that medication for 3-4 days and everyday my bpm went higher and then i quit it completely.

sometimes my heart rate just starts beating really fast and i can’t feal it pounding through my body and i get a tickle in my throat and when it stops it stops really abruptly and goes back to normal do you think this is sinus tachycardia?

Thanks for sharing! Perhaps a business card Dr. John Campbell M.D. Duke Would be fitting? I would be more than happy to write a letter a recommendation in terms of

How do you distinguish between sinus rhythm and pa ryrhmn n als situation

I have svt and it freaks me out but I havent had an episode in a long time thank god…but also I have bradycardia too 😒 why is this my life.

I had tachycardia when I was 7 and it was so painful. I had to keep standing up and down, whenever I stood up my heart rate would spike up

Please what is the difference between sinus tachycardia and svt

My heart rate is some times 35 and sometimes 135 bpm... What condition m i having... And how it can be treated

Short of breath...I get toted chest pain...sinus tachycardia...I have chest pain Heart rate , is 104 sometimes 134 or 99 ....my exg and cardiologist said heart is good...but I feel very cough...my heart..and short breath at night sleep and tensed anxiety and body sends abnormal rhythm stress and deep sharp stabbing chest pain in like costochondritis and back pain..behind heart region...I want to cure this permanently. Only 35

My heart very fast pounding actually IAM suffering from 6 years how can I treated

My heart beat during exercise increases 182 .... Is it harmfull ?

Am 16 and my heart rate some time goes 48bpm to 31 Bpm is that normal

My heart rate is sometimes between 55 and 60 is this considered bradycardia? I’m like 5’3 weighing 168lbs

I have hospital anxiety

Why am I even watching this? How did I get here?

If my resting heart rate stays at 54 -56 is that ok? Am I ok, will I be ok?

I have IST and POTS so I have tachycardia just about all the time

I have IST inappropriate sinus Tychardia

Hi sir what I would like to ask what is the mean of vertical heart?

tq sir I'm perfusionist perfusion important details take a class ple

Sir can we cure sinus tachycardia permenantly?? Please reply sir.......

I have sinus tachycardia, im getting hot very fast after walk or run. I had heart “burn” and pain in chest. Im very anxious and stressed. So i had blood tests and i have calcium a bit higher, LDL and HDL. Im 21yo, 165cm, 63kg. I cant find my doctor because of this corona situation.. im using propanolol (i have normal blood pressure 110-130). So if anyone have experience about this pls comment 🙂

Sir, I wanna become a doctor, because I love biology specially human physiology and anatomy. But I can't as I'm weak in chemistry and physics, What will I do?😖😭

I discontinued all potassium t.o.

I know this is an d video but some comments are just very mindless.Illness and disease don’t discriminate meaning doesn’t matter what age you are you can get an illness or a disease.Just the other day in the news they talked about a 17 year old having a massive heart attack.

can a Child have Tachycardia?

My heart is alway at 37 BPM I FAINTED IN A MATH ROOM BECAUSE OF MY PHOBIA CALLED NAGANUMEROPHOBIA FEAR OF NAGATIVE NUMBER

Wow

My hr spiked up to 189 age 13

the other day my bpm was at 34

I have sinus tachycardia:>

Who has sinus arrhythmia here??

😅😅😅
