How is the P wave produced in an ECG?
Atrial depolarisation
How is the QRS complex produced in an ECG?
ventricular depolarisation
How is the T wave produced in an ECG?
Ventricular repolarisation from apex to base and epicardium to endocardium
What is the sequence of conduction that produces the P wave?
What is the sequence of conduction which produces the QRS complex?
What is the sequence of repolarisation that produces T wave?
