5 days after left pneumonectomy patient was transfered from ICU to Med-Surg floor. about 30 min. later he developed tachycardia. HR was running between 130-140 bpm for 24 hours. Next day when the pt received d/c order he suddently went to v-fib. D/c order was canceled and pt stayed overnight. New orders were : cardizem drip, titrate and keep HR under 110 bpm; Amiodaron PO ( I think it was 400 mg BID).
My question: is it common when pt. becomes tachycardic after this procedure? Is it dangerous sign? Why is this happen?
