Hey all ...I have a question and I find myself prefering to ask it here among a court of my peers. In our E.R. have noticed that pts presenting with tachycardia sometimes symptomatic some times not..with otherwise stable VS, anf essianially negative lab work ups. Yet Low Kcl.levels ex: 3.2, 3.4 certainly not critical but still low...In my mind this tachy...seems corelated to the Kcl levels.....had a Doc..state in a rather condescending voice.." the potassium level has nothing to to do with (her) tachycardia" . Yet he was callin other docs in concern with this one pts.asymptomatic tachy( HR-120's) EKG nrml. I later looked up hypokalemia..and its symptoms..dysrhythmia is listed..isnt tachycardia a dysrhythmia?.....and wouldnt some simple potassium therapy help correct her Tach?...or am I just way they heck off base?.....Please set me straight/clear Thanks....

If the K+ isn't the cause, then treating with K+ isn't going to bring the HR down. Sometimes a problem with the SA node will cause the fast rate. I've seen cardiac meds given for this. We had a lady this weekend that was transferred to us with HR in the 170's to 180's, non-symptomatic, normal EKG -other than the SVT...K+ was fine. She got a Cardizem bolus and has been NSR in the 70's and 80's ever since.
Keep in mind...if the k+ level is too HIGH, you can have probs as well. So, if the K+ level is WNL, or just slightly low, that may not be the thing to give.
