What is the definition or description of: Atrioventricular node conduction block?

What is the definition or description of: Atrioventricular node conduction block?

Slow heart rate.: Atrioventricular block results from impaired or absent conduction of electrical signals from the upper to the lower chambers of the heart. This may be caused by increased nervous system activity, medications that slow conduction in the atrioventricular node, or damage to the atrioventricular node. The severity may vary from no symptoms to slowing of the heart resulting in dizziness or fainting. ...Read more

Are there better and newer treatments for atrioventricular node conduction block?

Not really: There are really no medical treatments for av block. Best treatment is to avoid the medications that cause it or make it worse. If the block is severe enough, pacemaker is usually the treatment. ...Read more

Are there some genetic reasons I get atrioventricular node conduction block off and on?

Are there some genetic reasons I get atrioventricular node conduction block off and on?

No: There are some genetic conditions associated with heart block, some associated with deafness. In these cases, the heart block is permanent. If your heart block is transitory, it may be related to some medications you are taking (if any) or underlying conditions, depending on your age. You should see a doctor to determine if further tests or treatments (e.g. Pacemaker) are needed. ...Read more

What is the purpose of the avn (atrioventricular node)?

What is the purpose of the avn (atrioventricular node)?

Brakes: This is specialized conduction tissue between the atria (upper chambers) and ventricles. The normal heart beat arises from the atria an passes through this node to the ventricles to stimulate contraction. If something goes awry in the atria causing a very rapid heart rate, the AV node will prevent some of these impulse from getting through, limiting how fast your heart will beat in response. ...Read more

What is the purpose of the avn (atrioventricular node)?

What is the purpose of the avn (atrioventricular node)?

Modulate impulses: The AV node is electrical tissue that separates the upper from the lower chambers of your heart. On an ECG, it relates to the PR segment. The AV node slows impulses briefly from the top to the lower chambers of the heart and prevents very rapid upper heart beats from causing dangerous fast heart beating of the major lower chambers of the heart. Blockage of AV node (ablation) stops impulses. ...Read more

What is the differences between sinoatrial and atrioventricular node?

What is the differences between sinoatrial and atrioventricular node?

Two diffent areas: Eletrical impulses to start the heart beating originate in the sinoatrial node near the top of the heart and travel down fibers to the ac node which is lower in the heart. ...Read more

What sort of problem is an atrio-ventricular node conduction block?

What sort of problem is an atrio-ventricular node conduction block?

AVB has 3 flavors: There is 1st, 2nd and 3rd degree av block. 1st degree is just slower conduction through av node than normal. In 2nd degree there is a progressive slowing of conduction until complete failure to get through and then the cycle repeats itself. It is usually not symptomatic. In 3rd degree there is no conduction getting through and the ventricles beat by an escape beat that is usually very slow. ...Read more

Can you help me understand this? POSSIBLE RIGHT VENTRICULAR CONDUCTION DELAY LEFT ANTERIOR FASCICULAR BLOCK POSSIBLE ANTERIOR MYOCARDIAL INFARCTION,

Abnormal EKG: Abnormalities of the electrocardiogram sometimes indicate a heart problem. The EKG should be reviewed by a cardiologist together with your history to determine the significance of the abnormalities and whether additional testing is needed. ...Read more

34 y/o m waking with "shiver up spine" sensation, chest/left arm. Mri, blood tests normal. Ekg-conduction block, dr. Says not it. Help with cause?

34 y/o m waking with "shiver up spine" sensation, chest/left arm. Mri, blood tests normal. Ekg-conduction block, dr. Says not it. Help with cause?

Not sure/ck. Heart.: This can still point to a problem with your heart since it seems to go to your left arm. Your age is somewhat early for heart disease, but a positive family history for coronary artery disease could still mean you have to check it out. This is still nonspecific, so it could also be an early ulcer, or possibly an aneurysm in the aorta which has back pain. A full workup by your doctor would help. ...Read more

I have a very high blood pressure of 155/80, diziness. Found "sinus tachycardia" and "intraventricular conduction block". in ECG. Is this dangerous..

I have a very high blood pressure of 155/80, diziness. Found "sinus tachycardia" and "intraventricular conduction block". in ECG. Is this dangerous..

Potentially: While a blood pressure of 155/89 is NOT "very high", if you have other risk factors for cardiovascular disease, treatment should be considered. Regarding the sinus tachycardia, the seriousness of it depends on what's causing it. The intraventricular conduction block, by itself, isn't dangerous, but it may be a sign of more serious heart problems. You are right to take this seriously. ...Read more

What is second degree atrioventricular block or wenckebach phenomenon. I am diagnosed with this.

What is second degree atrioventricular block or wenckebach phenomenon. I am diagnosed with this.

It means there is: A delay of the elcetrical message in your heart coordinating the squeeze between your left upper chamber (atrium) and the left lower chamber (ventricle). This is not serious and can be monitored by ekgs. ...Read more

Are there any treatments for atrioventricular block?

AV block: Av block occurs in first, second and third degree forms. First is usually benign, second can be serious and might need a pacemaker, third degree almost always needs a pacemaker. ...Read more

Does atrioventricular dissociation cause heart block?

Does atrioventricular dissociation cause heart block?

Heart Block: Yes av dissociation can cause heart block, like third degree heart block is complete av dissociation but all av dissociation are not heart block. ...Read more

Will atrioventricular dissociation lead to heart block?

Will atrioventricular dissociation lead to heart block?

Arrhythmia: Av dissociation is a disorder of conduction that in some cases (3rd degree av block) can lead to bradycardia (slow hr) and syncope. ...Read more

Does atrioventricular dissociation precede heart block?

Does atrioventricular dissociation precede heart block?

AV dissociation: Atrioventricular dissociation can occur with or without heart block. For example, during ventricular tachycardia, the ventricular impulses are usually not going retrogradely to the atrium, so there is av dissociation without any heart block. The important thing is whether av dissociation is resulting in a ventricular rate slow enough to be symptomatic with dizziness or syncope. ...Read more

My ECG test indicated 1st -deg atrioventricular block, complete right bundle branch block. What are my next steps?

See a cardiologist: The next step after finding an abnormal EKG on a routine exam is to determine why. This is where a cardiologist will be most helpful. He will determine wether there is underlying structural heart disease or not and will likely order testing to find out ...Read more

Can nerve conduction tests be wrong?

No: Though there are limitations on what a nerve conductions test can show. If it shows something (and is done by a knowledgeable physician), it is definitely there. It may not be sensitive enough to pick up subtle changes. Not every nerve condition is detectable by this test. If done too soon after an injury (less than 3 weeks), may not show up. If symptoms are worsening, it is worth retesting. ...Read more

Difference between nerve conduction study and emg?

Difference between nerve conduction study and emg?

See below: The EMG portion uses a small needle to directly examine muscle function, and the nerve conduction part uses electrical shocks to measure nerve function. Together the study gives a good idea of the nature of the pathology and location, but can also assess the prognosis and character, and gives often guidance towards an eventual diagnosis. ...Read more

What does a normal emg/nerve conduction test tell you?

Interpretation: Assuming the test was comprehensive and technically competent, this can eliminate large fiber neuropathy, and most muscle diseases. But does not eliminate small fibre neuropathy, or disease of brain and/or spinal cord. Symptoms due to intermittent nerve compression are not fully excluded either. ...Read more
