ECG Cardiac Cycle

Image Description:

An image showing an ECG Cardiac Cycle. The cycle can be split in to the following sections:

• P waves represent atrial depolarisation.
• The QRS complex represents depolarisation of the ventricles.
• The ST segment starts at the end of the S wave and ends at the beginning of the T wave.
• The T wave represents ventricular repolarisation.
• The RR interval begins at the peak of one R wave and ends at the peak of the next R wave.
• The QT interval begins at the start of the QRS complex and finishes at the end of the T wave.
