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

T waves on an ECG represent the repolarization of the ventricles of the heart, indicating the relaxation phase of the heart's electrical activity.
T waves in an electrocardiogram (ECG) represent the repolarization of the ventricles in the heart, indicating the recovery phase after contraction.
Two T waves on an ECG indicate that the heart's electrical activity is normal and functioning properly.
The absence of P or T waves on an ECG may indicate abnormalities such as atrial fibrillation, ventricular tachycardia, or electrolyte imbalances.
ECG waves represent the electrical activity of the heart, showing how it beats and functions. They can help diagnose heart conditions and monitor cardiac health.
In an ECG reading for atrial fibrillation (AFib), there will be irregular and rapid electrical signals in the atria, leading to a chaotic heart rhythm. This is shown as erratic waves on the ECG tracing. In a normal ECG reading, the heart's electrical signals follow a regular pattern, resulting in a steady and organized heart rhythm with distinct waves on the ECG tracing.
Yes, a flutter typically does not have distinct P waves present on an electrocardiogram (ECG).
Peaked T waves on an electrocardiogram (ECG) indicate a potential problem with the heart's electrical activity, which could be a sign of conditions like hyperkalemia or myocardial infarction.
