Flashcards in EKG Meds and Metabolic Derangements Deck (8)
-Sx of digoxin toxicity
-what rhythm is common with toxic levels of digoxin
EKG findings: scooped ST depression (slows down repolarization)
-should see this in ALL of the leads, if only in V5 V6 you are maybe worried about ischemia.
-N/V, anorexia, diarrhea
-blurred vision, yellow/green discoloration halos
-palpitations, syncope, dyspnea
-confusion, delirium, fatigue
-increased automaticity and decreased AV conduction
-Atrial tachycardia with block is a common rhythm of digoxin toxicity.* (supraventricular tachycardia with a slow ventricular response) AND everything bad that can happen on ekg...
-PAT w/ block
-peaked T waves* (eiffel tower) (may be as high as 15mm in precordial leads)
-Pwave flattening, widening, or no p waves.
-T wave flattening or possibly inverted
-irritation of ventricular foci which can lead to Torsades, VT, VF
-short QT interval & J waves
-prolonged QT interval
-frequenct PVC and PACs
-ventricular and supraventricular tachyarrythmias
-osborne wave (Jwave) is a positive deflection at the Jpoint most commonly seen in precordial leads
J waves may be seen in a number of other conditions...list some :)
-neurological insults such as intracranial HTN, severe head injury and subarachnoid hemorrhage
