Intrinsicoid deflection
Intrinsicoid deflection is a term used in Electrocardiography to describe the initial downward deflection in the QRS complex on the electrocardiogram. It is an important aspect of Cardiology and diagnostic medicine.
Definition[edit | edit source]
The intrinsicoid deflection is the time taken from the onset of the QRS complex to the peak of the R wave in the precordial leads. It is also known as the R wave peak time. This deflection is used as an indicator of the time taken for the depolarization wave to spread from the endocardium to the epicardium.
Clinical significance[edit | edit source]
The intrinsicoid deflection is used in the diagnosis of several cardiovascular diseases. An increased intrinsicoid deflection time can indicate Ventricular hypertrophy, while a decreased time can suggest a Myocardial infarction.
Measurement[edit | edit source]
The intrinsicoid deflection is measured in lead V6 of the Electrocardiogram. A normal intrinsicoid deflection time is less than 0.05 seconds.
