ECG changes typical for digitalisintoxication (digitalis = Lanoxin) are:
ECG changes typical for digitalisintoxication (digitalis = Lanoxin) are:
*odd shaped ST-depression.  
*odd shaped ST-depression.  
*T-wave flat, negative or biphasis
*T-wave flat, negative or biphasic
*Short QT interval
*Short QT interval
*Increased u-wave amplitude
*Increased u-wave amplitude

* '''anti-arhythmics:''' These may lead to several ECG-changes;
* '''anti-arhythmics:''' These may lead to several ECG-changes;
**brede en onregelmatige P-top
**broad and irregulair P-wave
**verlenging en brede QRS-complex
**broad QRS-complex
**verlenging QT-interval (brady-, tachycardieën, AV-blok, ventriculair tachycardie)
**prolonged QT-interval (brady-, tachycardia, AV-block, ventricular tachycardia)
**ontstaan van U-golf
**prominent U-wave
**bij intoxicatie is er een versterking van de bovengenoemde kenmerken--> ontstaat het effect van een glijbaan
**In case of intoxication, the above mentioned characteristics are more prominent


Daarnaast kunnen er als bijwerking ritmestoornissen optreden (pro-aritmische werking)
Additionally, several arrhtythmias can be seen.
