1...P wave...shows depolarisation of the atria
2...PR interval....time between the first deflection of P wave and first deflection of QRS complex.i means wave of depolarisation is now going to doplarize interventicular segment
3.QRS complex....means depolarisation of ventricles
4. means the resting phase of the heart when all chambers of the heart are in a phase of repolasrepolar
5.ST segment...it reflects the the period of zero potential between venttricular depolrization and repolrsation.
6.T wave...means repolarization of ventricles

Procedure 1 Interpreting an ECG You will now perform some basic ECG interpretation. Following are two tracings for which you will calculate the heart duration of key periods of the ECG. 1 Identify and label the P wave, QRS complex, T wave, P-R interval, R-R interval, and Q-T interval on Tracings 1 and 2 in Figure 11.27 Tracing 1 Tracing 2 FIGURE 11.27 ECG tracings 2 Cakulate the heart rate for each tracing, Are the values normal or abnormal? Heart...
