Which part of the ECG tracing does line 2 intersect? ________ Which part of the stethoscope tracing does this line intersect?

Solution

Answer: Part 1

The magnitude of the recorded voltage in the ECG is directly proportional to the amount of tissue being depolarized. Most of the mass of the heart is made up of ventricular myocardium. Therefore, the largest recorded waveform, the QRS complex, reflects the depolarization of the ventricles.

QRS interval caused by ventricular depolarization represents the majority of the electrical activity of the heart and causes Intersect 2.

Answer: Part 2
