FIRST DEGREE AV BLOCK ALL WAVES PRESENT NORMAL

FIRST DEGREE AV BLOCK ALL WAVES PRESENT, NORMAL AND CONSISTENT ATRIAL RATE 60 -100 BPM VENTRICULAR RATE 60 -100 BPM PR INTERVAL IS CONSISTENLY PROLONGED NO ARTIFACTS PRESENT RHYTHM IS REGULAR 1

SECOND DEGREE AV BLOCK; TYPE I ALL WAVES PRESENT; OCCASIONAL EXTRA P WAVE ATRIAL RATE 60 -100 BPM; SLIGHTLY HIGHER THAN VENTRICULAR RATE 60 -100 BPM PR INTERVAL PROGRESSIVELY LENGTHENS UNTIL QRS COMPLEX IS DROPPED NO ARTIFACTS NOTED RHYTHM ESSENTIALLY REGULAR UNTIL DROPPED QRS COMPLEX 2

SECOND DEGREE AV BLOCK; TYPE II ALL WAVES PRESENT; OCCASIONAL EXTRA P WAVE ATRIAL RATE 60 -100 BPM, SLIGHTLY HIGHER THAN VENTRICULAR RATE 30 -100 BPM PR INTERVAL NORMAL NO ARTIFACTS NOTED RHYTHM IS ESSENTIALLY REGULAR UNTIL DROPPED QRS COMPLEX 3

THIRD DEGREE AV BLOCK ALL WAVES PRESENT, WAVES ARE DISASSOCIATED, QRS IS WIDENED ATRIAL RATE 60 -100 BPM VENTRICULAR RATE 20 -60 BPM PR INTERVAL INCONSISTENT NO ARTIFACTS NOTED RHYTHM IRREGULAR 4

SINUS ARREST ALL WAVES PRESENT, NORMAL AND CONSISTENT; APPEARS TO HAVE DROPPED ONE OR MORE CYCLES ATRIAL RATE 40 -100 BPM VENTRICULAR RATE 40 -100 BPM PR INTERVAL NORMAL PROLONGED PERIOD OF BASELINE NOTED BETWEEN CYCLES ESSENTIALLY REGULAR WITH DROPPED CYCLE 5

RIGHT BUNDLE BRANCH BLOCK ALL WAVES PRESENT, QRS COMPLEXES WIDE AND NOTCHED ESPECIALLY IN V 1 ATRIAL RATE 60 -100 BPM VENTRICULAR RATE 60 -100 BPM PR INTERVAL NORMAL NO ARTIFACTS NOTED RHYTHM REGULAR 6

LEFT BUNDLE BRANCH BLOCK ALL WAVES PRESENT; QRS WIDE AND NOTCHED ESPECIALLY IN V 5, V 6 ATRIAL RATE 60 -100 BPM VENTRICULAR RATE 60 -100 BPM PR INTERVAL NORMAL NO ARTIFACTS NOTED RHYTHM REGULAR 7

LET’S PRACTICE! REMEMBER TO USE THE SIX STEPS TO EVALUATE EACH RHYTHM STRIP DETERMINE WHICH ABNORMALITIES ARE PRESENT IDENTIFY THE ARRHYTHMIA BY IT’S ABNORMALITY 8
