Final answer:
Wide QRS complex tachycardia can be caused by ventricular tachycardia, bundle branch block, or Wolff-Parkinson-White syndrome.
Step-by-step explanation:
A wide QRS complex tachycardia refers to an abnormally fast heart rate with a wide QRS complex on an electrocardiogram (ECG). There are several possible causes for this condition:
- Ventricular tachycardia: This is a potentially life-threatening arrhythmia where the QRS complex is broad and abnormal.
- Bundle branch block: A blockage or delay in the electrical conduction within the bundle branches of the heart can cause a wide QRS complex.
- Wolff-Parkinson-White syndrome: This is a congenital condition where an accessory pathway in the heart causes rapid conduction, resulting in a wide QRS complex.
It is important to determine the underlying cause of the wide QRS complex tachycardia in order to provide appropriate treatment.
