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.
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
The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG
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.
adrenaline speeds the heart and the ecg will reflect that.
the ECG signal is traveling faster than the pressure recording wave.
ECG recording over a prolonged period during which the patient can move around
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.
An ECG or EKG is a recording of the electrical activity of the heart. An echocardiogram is an ultrasound recording of the heart and its blood flow.
the P wave
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
A
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
P wave
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
oops
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).
