Final answer:
The term for two premature ventricular contractions are with different QRS wave shapes is ventricular ectopy.
Step-by-step explanation:
The term for the two premature ventricular contractions with different QRS wave shapes is known as
Ventricular ectopy.
Ventricular ectopy refers to abnormal electrical signals originating from the ventricles, causing the ventricles to contract prematurely. These premature contractions can result in QRS waves that look different from the normal QRS complex.
