Answer 1

Correct Answer: Z-Wave

Rationale:

An Electrocardiogram (E.C.G. or EKG) is a test that measures the electrical activity of the heart and is used to detect heart problems. The E.C.G. waveform consists of several key components which represent different phases of the heart’s electrical cycle.
The key components of an E.C.G. include the P-Wave, QRS complex (which includes the Q-Wave, R-Wave, and S-Wave), and the T-Wave. These waves correspond to the depolarization and repolarization of the atria and ventricles.
The P-Wave represents the atrial depolarization, which is the electrical activity associated with the contraction of the atria.
The Q-Wave is part of the QRS complex, which represents the depolarization of the ventricles, leading to their contraction.
The T-Wave represents the repolarization of the ventricles, which is the recovery phase of the ventricles before the next contraction.
There is no such thing as a Z-Wave in the E.C.G. Hence, Z-Wave is not a part of the E.C.G. waveform.

Explanation of Other Options:

P-Wave

Rationale: The P-Wave represents the electrical activity that triggers the atria to contract. It is an essential part of the E.C.G. waveform and is the first wave in the E.C.G. cycle.

Q-Wave

Rationale: The Q-Wave is part of the QRS complex, which represents the depolarization of the ventricles. It is a crucial component in diagnosing various cardiac conditions.

T-Wave

Rationale: The T-Wave indicates the repolarization of the ventricles, preparing them for the next cycle of depolarization. It is a vital part of the E.C.G. waveform.

Conclusion:

Among the given options, the Z-Wave is not a recognized component of the E.C.G. waveform. The E.C.G. consists of the P-Wave, QRS complex (including Q-Wave), and T-Wave, which are critical for understanding the electrical activity of the heart.
