ECG & Heart Sounds (Korean)
The beating of the heart is associated with electrical activity and sound. The pattern of electrical activity recorded at the body surface is called the electrocardiogram or ECG. The aim of this laboratory is for you to record and analyze an ECG from a volunteer, and to examine the relationship between the ECG and the characteristic sounds of the heart.
Figure. The cardiac cycle.
By the end of today's laboratory you will:
- Know where to place electrodes to record the standard limb lead ECG (leads I, II and III )
- Be able to identify the major components of the ECG (P wave, QRS complex, T wave) in these leads
- Be able to relate the electrical activity in the heart to these major components
- Be able to provide estimates of the timings of the components of the ECG and their magnitudes
- Know how to calculate heart rate from the ECG
- Explain the time relationships between the electrical activity of the heart (as recorded in the ECG) and the mechanical activity of the heart (as judged from the heart sounds)
