i was able to leave her hooked to the 12 lead ekg, but if i couldn’t, i am pretty sure there is a way i could have monitored a v lead by moving electrodes. anyone know the placements? maybe shoulder leads in normal, red to v2? i suppose if i did this for one cycle of depression, it would confirm accuracy.
what you are referring to is the “modified chest lead (mcl).” if you google modified chest lead there are several sites that discuss this. to monitor in a modified chest lead the right/left arm leads are placed in the normal position. the left leg lead is placed in the position of the precordial lead_ that you want to monitor, and you then monitor in lead iii. this is referred to as mcl_.
while the qrs complex will not duplicate what you would get on a 12 lead ekg, the morphology is similar and might be useful for identifying changes, however you have to be able to place your monitor in diagnostic, rather than monitoring mode.
personally, i think the best thing you could do is what you did: leave the 12 lead ekg attached an on. if you only have access to one machine, let someone take it if needed, and when they are done reattach to your patient.
hope this information was helpful.
