I am practicing to get my tele certification. The only thing I am having difficulty with is distinguishing between 2nd degree AV block type 1 and 2. I know that in type 1, usually the PR interval gets longer, longer, longer, then a block. But in some of my practice strips, this is not always the perfect case.
I figured someone here would be able to give a good explanation of the two!!! Thanks for any help. I take my exam on Thursday and I definitely want to pass. I've been an RN since the end of September and work on a tele floor, so it will be nice to finally read my own strips.:redpinkhe
You are dating a guy and you tell him to pick you up at 8 o'clock. Instead the first date he picks you up at 8:15..second date..8:30...third date....9:00.(PR INTERVAL is getting longer and longer.)
He always shows up (QRS) BUT IS ALWAYS LATE AND LATER LATER for each date. You forgive him but he starts all over again...8:15...8:30....9:00 HE IS PROGRESSIVELY LATE BUT ALWAYS SHOWS UP.
Second degree TYPE 1.
You are dating this guy for quite sometime now. He is still late.(PR INTERVAL) He is doing the same crap as before (SAME AS FIRST DEGREE) 8:15..8:30...(later and later each date) BUT THIS TIME.....Hes late...he's late...he's late..but then..HE DOESNT SHOW UP! (QRS) HE IS PROGRESSIVELY LATE and DOESNT SHOW UP.
But there is something about him you like and you forgive him and he does it all over...late..late..late..NO SHOW!
Second degree TYPE 2:
So you decide to have a talk with the guy. He said he is going to try to not be late.
He is still late but least he is constant. Instead of the agreed time of 8:00..he keeps showing up at 8:30...8:30..8:30..then BAM HE DOESNT SHOW UP. You are devesatated!
(ALSO HE COULD OF BEEN ON TIME ON TIME ON TIME (PR 0.12-.20) BUT AFTER AWHILE HE DOESNT SHOW UP (QRS) YOU HAD NO WARNING. YOU ARE HEART BROKEN.
HE IS CONSTANT BUT THEN FOR NO REASON DOESNT SHOW UP.
You forgive him and decide to marry this IDIOT WHICH LEADS TO THIRD DEGREE HEART BLOCK.
He is on the couch..always on the couch..always there doing his own thing. You are always there too (P wave) but you are doing your own thing as well.
HE IS ALWAYS THERE BUT YOU WANT NOTHING TO DO WITH HIM.
HEART RATE GIVES 3RD DEGREE AWAY...SLOOOOOW, dont confuse it for whatever reason with 1st DEGREE.
