Medicine For 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
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
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
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
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
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
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
Hi Jan, just wanted to let you know that I have C6 compression documented by neck spine MRI, nerve conduction studies and it is not postcholecystectomy syndrome as you diagnosed yesterday. Just goes to show you that medicine online doesn't work. I am st

Is a nonspecific intraventricular conduction delay with a left posterior fascicular block anything to be concerned with? Chest hurts! Normal echo.
Can you help me understand this? POSSIBLE RIGHT VENTRICULAR CONDUCTION DELAY LEFT ANTERIOR FASCICULAR BLOCK POSSIBLE ANTERIOR MYOCARDIAL INFARCTION,
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..
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
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
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
AV block: Fatigue is typical of complete av block, common with second degree av block and unusual with first degree av block. ...Read more
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

I was just told today I have 2nd degree atrioventricular block type 1...do I need to stop walking on treadmill? I haven’t scheduled my appointment with cardiologist yet probably next week. I only walk 2 miles at 3.0 takes me 40 min. Worn out when I’m fin
Yes: Slows down the heart rate by blocking the sinus node and there by slowing the av node. ...Read more

I'm curious as to what effect would lidocaine have on action potential generation and conduction?
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
Maybe uncomfortable: Most patient's tell me it was not as painful as anticipated. The ncs involves electrical stimulation of the nerves, the EMG involves inserting a very small needle into several mucles. I think most patients describe the test as uncomfortable not painful. ...Read more
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
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
