Hi friends welcome back to all our law this is quick internal medicine and today i’m gonna talk about the ekg findings due to what you call digoxin so digoxin is really very important drug and this is a really very important topic for your usmle or any other medical board examination or even for your clinical practice so digoxin you know very well it has a what
You call a characteristic effect on sd segment so remember it can’t actually affect the st segment okay so there’s a particular sign i would like to tell you in a digoxin we’re gonna have a two things two ekg changes two types of akg changes one that at the therapeutic levels okay one that is at therapeutic levels and another one is at what you call toxic
Levels so remember if it’s a toxic then you have to be very cautious you have to treat that that’s why you should know the ekg changes equation changes will help you to know whether the what is the level of the digoxin in the blood okay guys so try to memorize these changes these are really very important so let’s start about what you call changes that are
Seen at therapeutic levels therapeutic levels okay so ekg changes of due to digoxin on vertical therapeutic levels are one is reverse stick sign that is the sd segment depression you know guys this is a normal right right q r s and t right what happens the s t segment over here due to d g oxin duo c r d oxin the tall always will be there okay so this sign is
Known as what you call reverse stick sign sd segment depression okay and remember the second change will be reduction in the t wave size there will be reduction in the t waves size okay become a smaller and a shortening of what you call qd interval qd interval shortening okay these are the changes that takes place at the therapeutic levels okay now let’s talk
About the toxic levels what happens when there is a digoxin is at the toxic level first is the t wave inversion okay and we have different types of arrhythmias almost all arrhythmias can take place but especially remember sinus bradycardia then we have proximal atrial tachycardia with block then your ventricle ectopics then ventricular what you call by gemini
Ventricular tichycardia and we have what you call atrial ventricular block these are really very important guys so try to memorize these things very important in the toxic at toxic level the t wave inversion you see you see the different almost all admins but the most important being sinus bradycardia okay peroxisomal literal trichycardia with the block then we
Have ventricular ectopics ventricular by germany ventricular tissue cardia and atrophical block so this is really very important thank you so much for watching this video take care you
