Not true- sometimes with a relatively fast ST the P wave will get burried in the T wave of the previous complex- But it also depends upon exactly how you define SVT- as the term SVT in and of itself is rather broad technically speaking.
hello great video! i am confused on #3 can you explain what makes this SVT and not sinus tach. im not sure what the major difference is between SVT and VT. also for #9 i am confused b/c you wrote rapid ventricular tachycardia. or did you just mean tachycardia b/c then i would understand to continue monitoring.
What makes this SVT as opposed to sinus tach is rate- Sinus tach is most usually limited to UNDER 150 (some say 130). as for the rapid v-tach the thing is that it's a trick question really- the key is that it says the patient is not symptomatic. Of course even then, in the long term of things, we're still going to most likely cardiovert this patient with synchronized cardioversion in short order anyways. The catch is that in reality it would be extremely rare (if i'd venture to say it is even possible) for a patient to be in VT and NOT be symptomatic unless it is a short run that converts to something less ominous relatively quickly. However, all actuality a patient that's in VT for long will most likely convert to v-fib if things are allowed to take the natural course without intervention.
