A notched QRS complex on an electrocardiogram (ECG) typically indicates the presence of a conduction delay or abnormality in the heart's electrical system, often seen in conditions such as left or right bundle branch block. It can also suggest myocardial hypertrophy or other structural heart changes. In some cases, a notched QRS may be associated with specific cardiac conditions, such as hypertrophic cardiomyopathy. It's important for clinicians to interpret this finding in conjunction with other clinical data and ECG characteristics.

What is an electrocardiogram's QRS pattern?
QRS-- A pattern seen in an electrocardiogram that indicates the pulses in a heart beat and their duration. Variations from a normal QRS pattern indicate heart disease.
In a normal ECG trace, what does a QRS wave indicate?
the contraction of the ventricles
What does a inverted QRS wave indicate?
In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
What does an irregular mole indicate?
A cancerous mole may have ragged or notched edges.
What is QRS elongation medical QRS?
QRS elongation, also known as QRS widening, refers to an increased duration of the QRS complex on an electrocardiogram (ECG), typically exceeding 0.12 seconds. This elongation can indicate various underlying conditions, such as bundle branch block, ventricular hypertrophy, or electrolyte imbalances. It can suggest impaired conduction through the ventricles and may be associated with an increased risk of arrhythmias. Proper evaluation by a healthcare professional is essential to determine the underlying cause and appropriate management.
How many seconds are in a qrs interval?
The QRS interval, which represents the time taken for the ventricles of the heart to depolarize, typically lasts between 0.06 to 0.10 seconds. This translates to 60 to 100 milliseconds. Abnormalities in this interval can indicate various cardiac issues.
When was QRS Records created?
QRS Records was created in 1928.
What is difference between QRS duration and QRS interval?
Nothing, they are equivalent.
What does qrs in text messaging?
"QRS" generally means to send messages slower.
What does the normal QRS complex measure?
does a normal qrs complex measures <.12
What is resting height of QRS deflection?
The resting height of the QRS deflection, also known as the baseline or isoelectric line, refers to the level of the electrocardiogram (ECG) trace when no electrical activity is occurring in the heart. It serves as a reference point for measuring the amplitude of the QRS complex, which represents ventricular depolarization. Ideally, the QRS complex should rise above this baseline during a normal heartbeat, indicating proper electrical conduction through the ventricles. Any significant deviation from this resting height can indicate underlying cardiac issues.
Why does the QRS complex have the largest amplitude?
More cells depolarize during this QRS complex(ventricular contraction). The reason is because the muscle mass of the atria is small compared with that of the ventricles. The ventricles have a larger muscle mass. Therfore the electrical impulses within the atria are shorter and are less. The ventricles are larger so there is a larger deflection of the ECG when the ventricles are depolarised this is called the QRS complex
