|
|
|
apparent P wave that occurs at the end of the QRS complex.
|
|
|
acute widening of the QRS complex immediately after the R wave.
|
|
|
slurring of the upstroke of the first part of the QRS complex.
|
|
|
delay between the end of the P wave and the beginning of the R wave
|
Detailed explanation-1: -“ A delta wave is slurring of the upstroke of the QRS complex. This occurs because the action potential from the sinoatrial node is able to conduct to the ventricles very quickly through the accessory pathway, and thus the QRS occurs immediately after the P wave, making the delta wave.
Detailed explanation-2: -A delta wave occurs at the beginning of the QRS complex, usually causing a distinctive slurring or hump in its initial slope. A delta wave isn’t present in BBB. On the 12-lead ECG, the delta wave will be most pronounced in the leads “looking at” the part of the heart where the accessory pathway is located.
Detailed explanation-3: -The hallmark electrocardiographic (ECG) finding of WPW pattern or preexcitation consists of a short PR interval and prolonged QRS with an initial slurring upstroke (“delta” wave) in the presence of sinus rhythm.
Detailed explanation-4: -Kardia Advanced Determination “Sinus Rhythm with Wide QRS” indicates sinus rhythm with a QRS, or portion of your ECG, that is longer than expected. This could indicate a bundle branch block in which there is a delay in the passage of heart’s electrical signals along the bottom of the heart.
