There is not one video on this channel that I don't feel like commenting on and appreciating. Ma'am we are eternally grateful to you for sharing your immense knowledge with us and helping us on our journey to become great doctors! Thankyou so much ❤️❤️❤️

So much 💓. I am thankful

Thank you so much! I am a paramedic and a nurse, and I’m in nurse practitioner school. I had the question of why stemi looks the way it does. I had never heard of current of injury. I thank you so much for this explanation!

Glad to hear that

your lecture is great v well explained better than many others . mam i got a question at 4:25 you say there is a potential difference even at RMP but the ECG will record a straight line . why does the ECG record a straight line isn't it there is a potential difference between the injured point and normal point . why does the ecg not record any wave for this current ? i think there should be some changes in the PR segment at this point . isn't the ECG record the potential difference and make a wave on ECG paper according to its direction then why ECG not make any wave for this potential difference ?

You are the best mam ❤❤❤

Madam.. @5.35 Why didn't you draw the St segment as a straight line from the S wave.. (A little bit elevation in it - between S wave and J point) Please explain And at 10.25 also there is a little bit elevation between S wave and J point in lead 2 but not in lead 3 it goes as a straight line from the S wave.. What makes it different? Please explain

Oh I think you got it wrong that from where to extend the line to determine original state of voltage in heart. Just extend the TP segment backwards straight. You will get it. With this I suggest watch the video once more

Bear in mind , current of injury always travel from more depolarised cells to less depolarised cells.

Need to look into that

How the injured area is depolarised plz explain Bcz depolarisation is more positive inside but in injury there is leak of potassium then how it would be in depolarised state

@PhysiologyOpen

Жыл бұрын

Injured area - even sodium and calcium ions enter the cells. In healthy myocardium, at rest it is impermeable to these ions

thanks madam

If at rest there is an existing voltage difference wouldn't it show as a deflection instead of a straight line

@PhysiologyOpen

11 ай бұрын

Yes correct- deflection is actually the straight line above or below the isoelectric line…that’s why isoelectric line is ST segment and a line is drawn from deflected TP segment to determine elevation or depression

Ist u have to learn the action potential of cardiac myocyte then u can learn it

Question: Can you tell how will the record be in V2 in case of posterior wall infarction ? Watch the video, think and answer

@achieverspoint.3610

2 жыл бұрын

In posterior mi there will b st depression in v2 becoz it is electrically Opposite lead

@mohdyosri3622

Жыл бұрын

just reciprocal (mirror image to posterior leads) if STEMI shown in post. leads it will be as NSTEMI in V2 with tall R,,,, and unfortionetely its sometimes difficult to be differentiated from RVH and its strain pattern

Ma'am please tell how the physiology of each lead??

If there is any potential difference it will record a that potential which will be seen as a line. Wave is recorded when then there is continuous change in potential

@PhysiologyOpen

2 жыл бұрын

Obviously that line is not at zero , it will be either above zero or below zero potential..but we don’t know that until and unless we see that respect to ST segment

@muhammadhuzaifa8649

thank you mam i got it. in other words straight line doesn't,t mean zero potential it is called zero potential only at ST segment. so we have to compare the rest of waves and segment to it .
