Cardiac Conduction Defects
What type of cardiac conduction problems can adderrall cause if overused? Can it cause permanent svt?
Permanent SVT: Unlikely but may exacerbate svt.Get a more detailed answer ›
No not serious: Your rhythm is normal. The nonspecific intraventricular conduction defect means that your complexes are wide in no specific ( right or left bundle branch pattern) pattern. This can happen as you age, if you smoke, as part of ischemic or other heart disease. It depends on the context in which you had the ECG done. In general it is nothing to worry about but good to know and possibly have a copy ...Read moreSee 1 more doctor answer
Can congenital heart defects or certain drugs result in increased cardiac output? What else causes it? Mine is 7.2lmin squared.
CO = HR x SV: Cardiac output (co) is the volume of blood pumped per minute, and related to heart rate (hr) and stroke volume (sv) (volume per heart beat). It can be affected by many bodily activities. An increase in either hr or sv can result in inceased co. So any drug that increases hr (caffeine, etc) can result in incresed co. Certain congenital heart defects (such as septal defects) can alter co. ...Read moreSee 1 more doctor answer
Diagnosis 2/8 from 11/12 stress test. Fixed inferolateral apical defect, myocardial infarct, 2 month a-fib/electric shock. Do i need a cardiac cath?
Is it possible to have a genetic cardiac defect leading to ventricular arrhythmia/sudden death ... Even with no family history of any heart defect?
Yes: It is possible for all of your family to be heterozygous for an abnormality and therefore asymptomatic and you are homozygous and at risk. It is unlikely that you would have a problem of this nature and not have had serious symptoms or diagnostic evidence by the time you were 20. You need to get control of your anxiety. You have a normal echo and a loop recorder in place. Take your Xanax (alprazolam) and chill ...Read more
Confusing: Adults cardiologists often use the 3-letter acronym, chd, for coronary heart disease. Pediatric cardiologists use the same for congenital heart disease. Answer depends on who is using it usually. Always ask physicians to speak in words, not letters. They should. ...Read moreSee 1 more doctor answer
Test nerve function: They are a way to test the function of nerves in the body, looking for focal (like carpal tunnel) or generalized (like diabetic neuropathy) problems. They are performed by stimulating the nerve electrically (which feels like touching a doorknob after shuffling your feet on a carpet on a dry day), and recording the response. They are uncomfortable, but very helpful in clarifying a diagnosis. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Tolerable discomfort: There are two parts to an EMG test: nerve conduction studies and electromyography. Nerve conduction studies feel like a short, electrical impulse and are, in a word, annoying. Emg uses a fine wire electrode to record from muscles and feels like an insect bite. It is not as bad as a shot or IV or blood draw. Several muscles and several nerves are usually checked. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
See below: An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerve conduction studies measure how well and how fast the nerves can send electrical signals. An EMG is done to find diseases that damage muscle tissue, nerves. A nerve conduction study is done to find damage to the peripheral nervous system. ...Read moreSee 2 more doctor answers
Well: Semmes Weinstein is the name of type of monofilament that is used to assess integrity of tactile stimulation to see if you might have a discrepancy or possible neuropathy. Nerve Conduction Study is a test that evaluates the speed of signals through nerves. If there is a slowing of nerves it can suggest abnormalities. ...Read more
