Electrocardiographic Findings
- EKG changes are observed in 20% of patients who are at therapeutic doses
- Prolongation of the QTc, displacement of the ST segment, T wave abnormalities, QRS widening, supraventricular and ventricular tachycardias can all occur.
- In overdose, widening of the QRS is frequent, and there is also QTc prolongation
Examples
Shown below is an image of EKG in a patient of nortriptyline intoxication demonstrating wide QRS complex and prolonged QT interval
Shown below is an image of EKG in a patient of nortriptyline intoxication demonstrating wide QRS and peaked T waves.
Shown below are the EKG images of a patient with amitriptylin intoxication showing tachycardia with heart rate 130.
- Before treatment
- After treatment
