ECG changes typical for digitalisintoxication (digitalis = Lanoxin) are: | |||
* | *odd shaped ST-depression. | ||
*T- | *T-wave flat, negative or biphasis | ||
*QT | *Short QT interval | ||
* | *Increased u-wave amplitude | ||
* | *Prolonged PR-interval | ||
*Brady- | *Brady-arrhytmias: | ||
** | **Sinusbradycardia | ||
**AV | **AV block. Including complete AV block and Wenkebach. | ||
* | *Tachyarrhythmias: | ||
** | **Junctional tachycardia | ||
** | **Atrialtachycardia | ||
** | **Ventricular ectopia, bigemini, monomorphic ventricular tachycardia, bidirectional ventricular tachycardia | ||
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 fibbrillation'') may develop. | |||
