===Digoxin===
[[Image:med_digitalis.png|thumb|300px|Typical for digoxin intoxication is the odd shaped ST-depression]]
ECG changes typical for digoxin intoxication (digoxin = Lanoxin) are:
*odd shaped ST-depression.
Intoxication can lead to a SA-block or AV-block, sometimes in combination with a tachycardia. '''NB''' these effects are increased by hypokaliemia. In extreme high concentrations rhythmdisturbances (''ventricular tachycardia, ventricular fibrillation, atrial fibrillation'') may develop.

===Anti-arhythmics===
* '''anti-arhythmics:''' These may lead to several ECG-changes;
=== Nortriptyline intoxication ===

In hypothermia a number of specific changes can be seen;<cite>hypoth</cite>
* sinubradycardia
* ST-elevation (inferior and left precordial leads)
* Osborne-waves (slow deflexions at the end of the QRS-complex)
