Explain How Ecg (electro Cardio Gram) Nodes Are Represented?
ECG machine will show five waves PQRST • P Wave: It represents the normal atrial depolarization ( contraction of atria) • QRS Wave: It represents the depolarization of the right and left ventricles (Contraction of ventricles • T Wave: It represents the re-polarization of the ventricles (Relaxation of ventricles)
