What are the ECG characteristics of Atrial flutter?

1- Inverted P waves (F waves) in II, III and AVF. 2- saw-tooth pattern between QRS complexes in II,III and AVF. 3- Atrial rate is 250-400 and regular but ventricular rate depends on AV node and between 60-150 and typically regular. 4- QRS is not wide 5- T waves not identifiable.


If there is a complete block between the SA node and the AV node how would the ECG be affected?

The rate of P waves will be faster than the rate of QRS complexes.


In an ECG pattern the P-Q interval indicates how long it takes for the cardiac impulse to travel from the?

An ECG pattern the P-Q interval indicates how long it takes for the cardiac impulse to travel from the SA node through the AV node.


Does the ECG record the electrical stimulation of cardiac muscle by conduction system?

Yes, an ECG records the electrical activity produced by the heart as it contracts and relaxes. This includes the electrical stimulation of the cardiac muscle by the conduction system, such as the SA node, AV node, and Purkinje fibers.


What is AV junction delay?

Atrioventricular (AV) junction delay refers to a delay in the conduction of electrical impulses through the AV node, which connects the atria and ventricles of the heart. This delay can affect the timing of heartbeats, potentially leading to arrhythmias or other cardiac issues. It is often assessed using an electrocardiogram (ECG) and can be caused by various factors, including medications, ischemia, or structural heart disease. Monitoring and managing AV junction delay are crucial for maintaining effective heart function.


How would the ECG be affected If there is a complete block between the SA node and the AV node?

If the atrial conduction system (the SA node and bachmann bundles) and the ventricular conduction system (the AV node and purkinje system) are completely separated, third degree heart block develops. In this case, the SA node will continue to depolarize the atria at its own intrinsic rate and the ventricles will be depolarized by a focus either in the AV node or in the ventricles.


What is meant by AV delay and what purpose does the delay serve?

The term AV delay refers to Atrioventricular Node delay. It is an important function in the human body as it makes sure that the atria have gotten all of their blood transported to the ventricles before they contract.


What size is the AV node?

AV ~1x3x5mm


Correct order of intrinsic cardiac conduction?

Its one of these, cant remember which one though: AV node, SA node AV bundle, Purkinje fibres. SA node, AV bundle, Purkinje fibres, AV node. SA node, AV node, AV bundle, Purkinje fibres. Purkinje fibres, SA node, AV node, AV bundle.


Which camcorder has av in?

Many models of camcorder have AV In.


Is av used in Scrabble?

No. Av is not allowed in Scrabble.


What happens during the p-r interval?

During the P-R interval on an ECG, the electrical impulse travels from the atria to the ventricles through the AV node and the bundle of His. It represents the time it takes for the atrial depolarization to reach the ventricles, allowing for coordinated contraction and efficient pumping of blood.
