P wave - represents atrial depolarization (contraction)
QRS complex - ventricular depolarization
T wave - ventricular repolarization (relaxation)
atrial repolarization is "buried" within the QRS Complex

What is R-R interval in an ECG?
the time between the two R waves in ECG
How many deflection waves in an ecg?
6
ST and T waves are elements of?
ecg
What is the first wave of an ECG?
I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order. P Wave, Q-R-S Waves and the T Wave
What does high T waves on ECG mean?
High potassium in cells. hyperkalemia
Who assigned the letters associated with the formation of the PQRST waves on an ECG?
Wilhelm Einthoven
Why are the waves in the same direction in an ECG?
The wave direction indicated whether the electrical impulse from the heart is going towards or away from the ECG lead that is being studied.
What waves are found on an electrocardiogram?
There are no waves in an electrocardiogram. An electrocardiogram (ECG) is performed by putting electrodes on the body and measuring heart activity directly.
The deflection waves in an ecg tracing include?
the T wave, which indicates ventricular repolarization.
Deflection waves in an ECG tracing include?
the T wave, which indicates ventricular repolarization
What is the flat horizontal line that separates the various waves of the ECG cycle?
its a flat horizontal line separator....
What change in polarization is the t waves on an ecg tracing?
t wave just appears before the ventricular relaxation
