Question	Answer
vary .08 sec bw r - r intervals	rhythm regular
varience greater thatn 0.08 sec bw r - r interval . may occur due to one isolate early or late beat or pause . may be completely irregular with no consistency bw r - r interval .	irregular rhythm
irregular or regulat with 1 early / late beat	how is a irregulart heart beat charted?
divide 300 by the number of large squares bw r waves	how to calculate rythm if it is regular?
count number of r waves and multiply by 10 = 6 sec strip	how to calculate if 6 secnd strip?
p = present or abscent, shape - upright or inverted, constant or varing Pr interval = width, fixed or variable qrs = width, shape - normal, wide or bizarr, varing in shape	how to chart p, pr, qrs complex, what comes next?
floating, prejelled, cushioned, conduct for 24 hourse shave area as needed. avoid bony protuberance, joints, and skin folds prep area with alcohol and let dry attach lead wires and apply electrodes to pt.	electrodes characteristics?
determine which leads are positive and negative than the monitor will select which one is positive negative and ground lead 1 11 111 lead wires are often labeled RA LA LL whci is were the electrodes should be placed RA right arm or shoulder LA left arm or shoulder LL l eft leg(reference lead or ground usually placed on the 6th - 7 th rib left antirior axiliary line)	lead placement?
lead l = RA negative LA positive LL ground lead ll = RA negative LL positive LA ground lead lll = LA negative LL positive LA ground	if lead l if lead ll if lead lll
low gain setting on ecg monitor poor electrode contact and or disconnected electrode disconnected or broken lead wire loose cable connection from monitor loss of amplitude of QRS insufficinet decrease in low rate alarm setting below pts own rate	low voltage signal cause ?
intervnetion Increase Gain Setting On Ecg Monitor Check Connections At lead Wires And Cables Reapply Electrodes If Required Repostiions Pt And Or Leads	LOW VOLTAGE SIGNAL
