No. Not everyone with heart failure will benefit from CRT. In general, patients who are good candidates for a CRT device are those with: Moderate to severe heart failure symptoms (for example, difficulty breathing or extreme tiredness), despite other therapy electrical problem that causes uncoordinated pumping of the ventricles (Learn more about the heart's electrical system.) Patients who respond favorably to other treatments, such as lifestyle changes and medication, may not need a CRT device.

When the flame goes out, the unit tries to reignite and does not give any system failure alarm. After 10 tries, the system failure alarm will activate. The system alarm is failsafe. See similar questions...

and device failure. Since you are making a decision that will impact your life for a long time, the long term reliability of the internal device is an important consideration in choosing your cochlear implant. Overall, cochlear implants are very reliable. However, reliability does vary from manufacturer to manufacturer. It is important that you investigate this as part of the CI decision by discussion it with your surgeon or audiologist or by contacting the manufacturers. See similar questions...

The typical failure mode of the device is to fail in a high resistance state. This means that the device does not return to its original low resistance value such that it can maintain the original specified hold current. In order to achieve UL recognition, the device must meet two criteria: (1) be tripped 6,000 times and still exhibit PTC behavior and; (2) stay in a tripped state for over 1,000 hours while exhibiting PTC behavior.

NFPA 70E: 130.1 requires employers perform a flash hazard analysis to identify work tasks performed on energized electrical conductors. Appropriate flame retardant clothing (FRC) as well as voltage rated tools may then be selected. See similar questions...

Yes, FRC garment care and laundering requirements are specified by ASTM F1449 (2001 Edition): Standard Guide for Care and Maintenance of Flame, Thermally and Arc Resistant Clothing. In addition, inspection requirements for FRC garments are outlined in NFPA 2113 (2001 Edition): Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire. No, the hazard risk category (HRC) classifications are based upon estimated incident energy. See similar questions...

Reporting multiple failures in a single test is generally a sign that the test does too much, compared to what a unit test ought to do. Usually this means either that the test is really a functional/acceptance/customer test or, if it is a unit test, then it is too big a unit test. JUnit is designed to work best with a number of small tests. It executes each test within a separate instance of the test class. It reports failure on each test. See similar questions...

Solution: The exterior termination cap on your exhaust system must constantly be free of any element that could block it, such as snow, ice, bird nests, etc. Sometimes, wind may cause a turbulence zone that will cause the burner and the pilot to shut off. If your burner or pilot flame has gone out during a very windy day, there may be nothing wrong with your fireplace. Simply re-light the fireplace. Solution: B-Vent gas fireplaces have a thermal switch. See similar questions...

The typical failure mode of the PolySwitch device is to fail in a high resistance state. This means that the device does not return to its original low resistance value and will not maintain the original specified hold current. In order to achieve UL recognition, the device must meet two criteria: If a device is subjected to fault events that exceed its rated voltage and current, or is exposed to multiple trip events that exceed the UL test conditions, the device may exhibit arcing and flame.

Run Sigverif.exe from a command prompt to verify that all the drivers are signed. If a device fails and its driver is not signed, replace the driver with the original and retest. If you determine that the problem is the result of a recent driver or hardware change to the system, undo that change. For more information about the File Signature Verification tool, see article Q259283 at http://support.microsoft.com/support/kb/articles/Q259/2/83.asp. See similar questions...

Chances are, the wick has been cut too short. If a wick becomes too short to light, carve away enough wax around the wick(s) in order to re-light the wick(s). You may get a fairly large flame at first, but as the melt pool expands, the level of the melt pool will rise, creating a smaller flame. When you have achieved a full melt pool, you can extinguish the flame(s), let the wax cool, then trim again if necessary. See similar questions...

Heart failure is a clinical syndrome said to present when the heart fails to adequately pump enough blood to meet the body's needs. The terms congestive heart failure or "CHF" are also used to describe this syndrome. Symptoms a patient may experience include exertional fatigue, shortness of breath with activity, shortness of breath lying down, and shortness of breath at rest. See similar questions...

Hyperparathyroidism occurs in most dogs and cats with chronic renal failure. Its extent is proportional to the increases of serum creatinine, and is quite directly related to the extent of uremic hyperphosphatemia. Serum phosphorus (Pi) is elevated primarily because of failure of renal excretion but its level is also affected by dietary intake, use of intestinal phosphorus binders and to some degree by the extent of PTH-mediated bone resorption. See similar questions...

The current state of knowledge of calcitriol-PTH relationships allows better interpretation of the classical views that the genesis of hyperparathyroidism in chronic renal failure is due to (a) hypocalcemia, (b) increased skeletal resistance to PTH, and/or (c) increased parathyroid gland set point for calcium suppression of PTH secretion.

First and foremost we must understand what failure really is. It's the same with everything we fear. Understand it and the fear will start to disappear. Take the cave-men for example, when they see lighting they were fearful ? because they don't understand it. Now let's analyse a case. A person wanting to climb up to the summit of a mountain. Do you think that throughout the journey he may not slip or step wrongly at all? Sure he would slip sometimes, step wrongly at times. See similar questions...

In the event of power failure the system is equipped with a heavy-duty backup battery. It will recharge itself once the power returns. Our basic alarm system does not talk to you. However we do have systems that can talk to you. This can especially be an advantage for the blind or for people where eyesight is a problem. The security consultant can better advise you on which system would best suite your needs. See similar questions...
