Question

Which of the following is shown on the EKG Tracing? Hint- *Spike* .

1) QRS Complex
2) T Wave
3) P Wave
4) U Wave

Answer 1

The 'spike' hinted at in an EKG Tracing corresponds to the QRS complex, indicating the depolarization of the ventricles.

Step-by-step explanation:

When referred to which of the following is shown on the EKG Tracing with a hint of 'Spike', the correct answer is the QRS complex. This portion of the EKG represents the depolarization of the ventricles, which is a much stronger electrical signal due to the larger size of the ventricular cardiac muscle. The spike mentioned refers to the sharp and tall waves that make up the QRS complex, with the R wave typically being the tallest peak. In contrast, the P wave represents atrial depolarization and is smaller, while the T wave indicates ventricular repolarization and follows the QRS complex. The U wave is a small wave that sometimes follows the T wave but is not commonly focused on when talking about spikes in EKG tracings.
