Digitalis/Digoxin
-EKG findings
-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.

Toxicity sx:
-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
-Sinus Block
-AV blocks
-VT/VF
-PVC

2

Hyperkalemia
-ekg findings

EKG:
-peaked T waves* (eiffel tower) (may be as high as 15mm in precordial leads)
-Pwave flattening, widening, or no p waves.
-QRS widening

3

Hypokalemia
-ekg findings

-U waves*
-T wave flattening or possibly inverted
-irritation of ventricular foci which can lead to Torsades, VT, VF

4

Hypercalcemia
-ekg findings

Hypocalcemia
-ekg findings

-short QT interval & J waves

Hypocalcemia:
-prolonged QT interval

5

Hypomagnesemia
-ekg findings

-prolonged QT
-torsades
-frequenct PVC and PACs
-ventricular and supraventricular tachyarrythmias

6

Hypothermia
-ekg findings

-osborne wave (Jwave) is a positive deflection at the Jpoint most commonly seen in precordial leads

7

J waves may be seen in a number of other conditions...list some :)

-hypercalcemia
-medications
-neurological insults such as intracranial HTN, severe head injury and subarachnoid hemorrhage

8

Pulmonary Embolus
-ekg findings

-sinus tachycardia** (first change you will see)
-S1Q3T3
-RAD
-Transient RBBB
-Twave inversion V1-V4
