What 3 electrical waves are present in an EKG?
|
|
P wave, T wave, QRS complex
|
|
|
T wave, U wave, R complex
|
|
|
All of the above

|
|
None of the above

Explanation:
Detailed explanation-1: -The three main components are P wave, QRS complex and T wave. The P represents depolarization of the atria, QRS complex denotes the depolarization of the ventricles and finally, the T wave represents repolarization of the ventricles.
Detailed explanation-2: -The P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.
Detailed explanation-3: -Each ECG cycles consists of 5 waves: P, Q, R, S, T corresponding to different phases of the heart activities.
