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 ›
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
VER: A very nice test can be done to measure the optic nerve conduction velocity. This is the visual evoked response or ver. A p100 can be measured that can be compared with the normal range for the laboratory where the testing is done. Delays in conduction can be seen in a variety of disorders, most common with the diagnosis of multiple sclerosis. ...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
