Respuesta :
An electrocardiogram is a diagnostic test that uses electrical activity to check the heart's rhythm. The distorted QRS complex of ECG can be premature ventricular contractions. Thus, option 4 is correct.
What are Premature ventricular contractions?
Premature ventricular contractions are heartbeats that are extra in number than the regular and occur in the ventricles of the heart. These extras alter the heart rhythm and QRS complexes.
The wide and distorted QRS complex gets altered in patients with ventricular fibrillation due to premature impulses in the ventricle. This leads to constant palpitations.
Therefore, in option 4. the disturbed QRS shows Premature ventricular contractions.
