AND all these leads look at the heart form deferent angles...👇👇

And they are shown in this pectures...👇👇

-but there are 12 leads which will be shown in the ecg paper... -AVF -AVR -AVL -lead I -lead II -lead III -Leads form V1 TO V6 12 right....🙃

10 right..? 🙃

So in standard ECG There is 10 electrodes which are in this picture...👇👇👇

السلام عليكم و رحمة الله ...✋ -Hi every one there is just a point which usually cause confusion in ECG ....that i want to crelfy... So read sllllllllllowly...🙃.. -and it is that what is the deference between ECG leads and electrodes ?!!!🤷‍♂

⭕But to take it as a general rule ....because there are a lot of drugs which are receptor #agonists and some are receptor #antagonists So what is the deference?!!! An agonist is any chemical that binds to a receptor and #activates the receptor to produce a biological response. Whereas an antagonist #blocks the action of the agonist....you get it...🙃🙃

-so in summary the beta 2 agonists are a group of drugs that selectively mimic the actions of the endogenous catecholamines epinephrine (adrenalin) and norepinephrine....which is bronchodilation.... -which make sense if you are running from a dog...🏃‍♂🏃‍♂🏃‍♂🐶🐶 you need more oxygen....so your bronchioles dilate.... -I'm really #sorry about this unintended mistake😔

بندي beta 2 agonist drugs

-Always remember that: #S3(when it pathological) is usually related to dilation of the ventricles .... #S4 is the sound of hypertrophy...🤔 Because it is produced due to the blood being forced into a stiffed or hypertrophic ventricle....

-The best way l know for studying is #SCAR .... -Stop -Complaining -And -Read 😒😊😊 So you just need to sit down and read I mean like a lot...😅 and then evry thing will fall into place....
