Question

Abnormally slow conduction through the

ventricles would change the shape of the
______ in an ECG tracing.
A. P wave
B. T wave
C. QRS complex
D. P–R interval
E. R–T interval

Answer 1

Answer: C. QRS complex.

Step-by-step explanation:

Abnormally slow conduction through the ventricles is known as bundle branch block or intraventricular conduction delay, and it can result in a widened QRS complex on an ECG tracing. This is because there is a delay in the spread of electrical impulses through the ventricles, causing them to contract later than they should. The P wave, T wave, P–R interval, and R–T interval are generally not affected by ventricular conduction delays.
