I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order.

Atrial repolarization coincides in time with?
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG
What happens during p wave of an ECG recording?
The P Wave on and ECG shows depolarization of the Atria, and the characteristics should be smooth, round, no more than 2.5 mm in height, no more than .11 seconds in duration, and positive in leads I,II, aVF, and V2 through V6.
What changes can occur on ECG due to coronary artery disease?
The ECG shows ST elevation or depression and pathological Q waves. The pathological Q wave is a sign of an old infarct (heart attack) as the muscle doesn't conduct an impulse at a certain point.
What are the effects of adrenaline on ECG?
adrenaline speeds the heart and the ecg will reflect that.
Does ecg hurt?
NO
The portion of the ECG that corresponds to atrial depolarization is the?
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
What is the ECG wave that results from the depolarization of the ventricle?
the P wave
What portion of the ECG indicates ventricular repolarization?
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
Why is the T wave positive in the ECG?
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
What contraction of the atria results from which wave of depolarization on the ECG tracing?
P wave
What is QRS in ECG?
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
If you have an ECG conducted what causes the P wave?
oops
What are the 3 components of the ECG trace?
The EKG or ECG components are the P wave (contraction of the atria), the QRS complex (the contraction of the ventricles) and the T wave (repolarization of the ventricles).
How does hyperkalemia relate to the ECG?
Hyperkalemia cause tall t wave and wide qrs wave
What ecg curves represent recovery of the ventricles?
t wave
What does the ecg wave tracing represent?
Electrical Activity of the Heart
What part of the ECG records atrial contraction?
ECG records electrical activity and not mechanical, hence it has nothing to do with contraction. But P wave represents atrial depolarization.
