Study Notes
- An ECG tracing shows the electrical activity of the heart.
- During asystole, the ECG tracing would show a flatline, which is a straight horizontal line indicating that there is no electrical activity in the heart.
- During diastole, the ECG tracing would show a series of peaks and troughs representing the electrical activity of the heart as it contracts and relaxes.
- The peaks, called "QRS complexes," represent the contraction of the ventricles, while the troughs, called "T waves," represent the relaxation of the ventricles.
- The distance between each peak and trough represents the duration of diastole, which is the time when the heart is filling with blood.
