On the QT Origin. The slang term 'qt' is a shortened form of 'quiet'. There's no definitive source for the phrase ' on the q.t .', although it appears to be of 19th century British origin-not, as is often supposed, American.The longer phrase ' on the quiet ' is also not especially old, but is first recorded somewhat before ' on the qt ', in Otago: Goldfields & Resources, 1862:ll early citations of the phrase have it as 'on the strict q.t.'. The first recorded use of any version of the phrase in print that I can find documentary evidence for is by the Irish novelist George Moore, in A mummer's wife 1884: . It will be possible to have one spree on the strict q.t..

prolonged QT syndrome This electrical activity, in turn, is the result of small molecules (ions such as sodium and potassium) passing in and out of channels in the membranes surrounding heart cells. A prolonged QT interval indicates an abnormality in electrical activity that leads to irregularities in heart muscle contraction. One of these irregularities is a specific pattern of very rapid contractions (tachycardia) of the lower chambers of the heart called torsade de pointes, a type of ventricular tachycardia.

- QT Interval. 1  The QT interval is the time from the start of the Q wave to the end of the T wave. 2  It represents the time taken for ventricular depolarisation and repolarisation.

- 1 TID, also t.i.d., is a medical abbreviation for ter in die, meaning to give medication three times a day. 2  QID also q.i.d, is a medical abbreviation which means to give the medication four times a day.  PRN is a medical abbreviation for pro re nata, meaning to give medication as the situation demands or according to need.

QT interval QT interval. In cardiology, the QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle. The QT interval represents electrical depolarization and repolarization of the ventricles. A lengthened QT interval is a marker for the potential of ventricular tachyarrhythmias like torsades de pointes and a risk factor for sudden death.

- The condition is named for the appearance of the electrocardiogram (ECG/EKG) on which a prolongation of the QT interval occurs. Normally, the QT interval duration is between 350 and 440 milliseconds. In some individuals, the QT prolongation occurs after the administration of certain medications, which may be dangerous.

- The QT interval represents the time from the electrical stimulation. (depolarization) of the heart’s pumping chambers (ventricles), to their recharging. (repolarization). It is measured in seconds on the EKG and closely approximates. the time from the beginning of the ventricles’ contraction until the end of.

What does a Quality Assurance Technician do? You won't believe these 10 facts about people. A quality assurance (QA) technician reviews products and services to make sure they meet certain standards of quality. In many companies, the quality assurance/ quality control (QC) lab or department is a focal point of the corporate mission and administration. Because of the importance of quality, this technician must often be highly educated and experienced in the particular manufacturing methods and products he or she deals with. Quality assurance is accomplished by a variety of methods depending upon the product or service to be assessed.

The QT interval: How long is too long? The long and short of it. The QT interval on the ECG is measured. from the beginning of the QRS complex to. the end of the T wave (see ECG components). It represents the time it takes. for the ventricles of the heart to. depolarize and repolarize, or to. contract and relax. The QT interval is longer when. the heart rate is slower and short-. er when the heart rate is faster.

Sudden Cardiac Arrest Long QT syndrome (LQTS) is a disorder of the heart's electrical activity. It can cause sudden, uncontrollable, dangerous arrhythmias (ah-RITH-me-ahs) in response to exercise or stress. Arrhythmias are problems with the rate or rhythm of the heartbeat.People who have LQTS also can have arrhythmias for no known reason.ong QT syndrome (LQTS) is a disorder of the heart's electrical activity.

Long QT syndrome The upper limit of a normal Q-T interval takes into account age, sex, and regularity and speed of the heart rate. Long QT syndrome results from abnormalities in the heart's electrical recharging system. However, the heart's structure is normal. Abnormalities in your heart's electrical system may be inherited or acquired due to an underlying medical condition or a medication.

Arrhythmias The electrical activity that occurs between the Q and T waves is called the QT interval. This interval shows electrical activity in the heart's lower chambers, the ventricles (VEN-trih-kuls). The timing of the heart's electrical activity is complex, and the body carefully controls it.

What does qd mean? What does qd on a prescription mean? QD is Latin for quaque die which means once a day. For example, if your prescription says PO QD it means you are suppose to take your medications by mouth once a day. There …is another abbreviation that can be confused with QD, which is QID. QID is Latin and stands for quater in die which means four time a day.

Publications QT prolongation is a measure of delayed ventricular repolarisation. Excessive QT prolongation can predispose the myocardium to the development of early after-depolarisations, which in turn can trigger re-entrant tachycardias such as TdP.
