Question

Quizplus · Accepted Answer

The electrocardiogram is a recording of the electrical activity of the heart and provides information about the heart rate, condition of the conducting system, and effects of drugs and poisons. However, it does not directly reveal information about stroke volume, which is the amount of blood pumped out of the heart with each beat. Stroke volume is typically measured using other techniques, such as echocardiography. The electrocardiogram may indirectly provide information about stroke volume by reflecting changes in electrical activity that can be associated with changes in cardiac function, but it is not a direct measure of stroke volume. Similarly, the duration of the ventricular action potential is not directly revealed by the electrocardiogram, but rather inferred from changes in the shape and timing of the ECG waveform.
