ARE THERE GENDER DIFFERENCES IN LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
Studies show there are significant gender differences in genotyped LQTS patients relative to age of first episode, syncope, cardiac arrest and sudden death. Males seem to have a higher risk of cardiac events (meaning syncope or blackout spells, cardiac arrest and sudden death) during childhood (with an average earlier age of onset in males at 8 years old vs.14 years in females), through puberty. Studies reveal females have an increased risk relative to males during adulthood.

WHAT IS THE LONG QT SYNDROME (LQTS)?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The long QT syndrome (LQTS) is causing an abnormality of the heart's electrical system. The mechanical function of the heart is entirely normal. The electrical problem is due to defects in heart muscle cell structures called ion channels. These electrical defects predispose affected persons to a very fast heart rhythm (arrhythmia) called "Torsade de Pointes" (TdP) which leads to sudden loss of consciousness (syncope) and may cause sudden cardiac death.

HOW IS LONG QT SYNDROME DIAGNOSED?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The diagnosis is commonly suspected or made from the electrocardiogram (ECG). All children and young adults should have an ECG as part of their evaluation for an unexplained loss of consciousness episode. On the other hand, there is the possibility to check blood samples for known gene mutations that cause LQTS.

CAN PREGNANCY BE A TRIGGER IN LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The 9-month interval during pregnancy and the delivery itself are not associated with an increased occurrence of heart events in any of the LQTS women. However, it appears that the physical and emotional stress during the 9-month period after pregnancy (the postpartum period) may be a factor in triggering heart rhythm disorders in some vulnerable women with LQTS.

WHY IS THE DISEASE NAMED LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The name of the long QT syndrome refers to the QT-interval measured on the electrocardiogram (ECG or EKG for the German term "Elektrokardiogramm"). Your specialist may refer to long QT syndrome as Romano-Ward syndrome or Jervell, Lange-Nielsen syndrome (see point 3).

WHAT DOES MEDICINE KNOW ABOUT LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
INHERITED: Inherited long QT syndrome was first clearly described in 1957. There are two variants, the autosomal dominant Romano-Ward (named by the doctors who first described the disease, O. Connor Ward and C. Romano) type and the autosomal recessive Jervell, Lange-Nielsen (Doctors A. Jervell, F. Lange-Nielsen) type. Inherited long QT syndrome is caused by mutations of at least 9 genes, and possibly more. Five different genes have so far been found.

HOW COMMON IS INHERITED LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The frequency is unknown but it appears to be a common cause of sudden and unexplained death in children and young adults. It is certainly much more common than previously thought. It may be as frequent as 1 in 5000 to 7000. This means, one of 5000 to 7000 newborns have the disease. The Jervell, Lange-Nielsen form is rare, but the Romano-Ward variant is being recognized with increasing frequency. In the USA, the presence of long QT syndrome is estimated to affect about 50.

IS LONG QT SYNDROME ALWAYS OBVIOUS ON THE ECG?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
It is generally estimated that approximately 10% to 12% of all patients with long QT syndrome show a normal QT-interval on their ECG. However, this does not mean that these patients are not affected by long QT syndrome. In such cases, a more profound evaluation is needed.

CAN HEAT BE A TRIGGER IN LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
It has been noticed that several cardiac arrests occur during summer time. But it is not sure if it this may be an excess in statistical terms. It is however hard to define if these cardiac arrests are related to a specific "risk" due to heat or sweating or if it is mainly a reflection of increased physical activity, excitement and playing during the summer.

CAN AN AUTOPSY REVEAL LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
There are two ways to make a diagnosis for QT syndrome. The first is to check if the QT-interval on the ECG of a suspected patient is prolonged. Because the heart stopps beating when death occurs, this possbility is out of question - except an ECG of the dead person already exists, of course. The only possibility would be to check body fluids of the dead person - in this case blood - for the known gene mutations that cause QT syndrome.

DO GENERIC BRANDS OF BETA BLOCKERS ALSO PROVIDE A COMPLETE PROTECTION AGAINST LONG QT SYNDROME?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
Most of the studies in the medical literature confirm that no major differences exist between brand and generic drugs. However it is fair to recognize that occasional reports have raised concern that certain generic brands may be less effective than brand name products (see: Cervera Barba EJ. [Increase of arterial pressure caused by generic atenolol] Aten Primaria. 2001 Feb 15;27(2):146-8).

Are there other gender differences when it comes to heart disease?

LifeHeart.com
Yes, many. Women who have heart attacks are more likely to die from them. New research suggests that having diabetes is a much stronger risk factor for heart disease among women than men. Also, women get Syndrome X more often, a type of angina in which chest pain occurs, but heart arteries appear normal on X-rays. Such factors lead some doctors to advocate taking female physiology and symptoms into account in research, prevention and treatment. Visit Women and Heart Disease for more information.

Are there any gender differences in frequency of vomiting?

Frequently Asked Questions about Vomiting
Are there ever! In the survey of non-emetophobics, women reported having vomited 4.9 times on average in the past year, while for men the figure was only 1.4 times. The women said a typical year for them is 1.49 illnesses causing vomiting on average while men reported .9 such illnesses. All of the measures find women vomiting more often than men. The median woman most recently vomited 155 days ago; for the median man, it was 189 days. The differences in the average are even more striking.

WHAT IS THE QT-INTERVAL?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The duration of the QT-interval is a measure of the time required for depolarization and repolarization to occur. In long QT syndrome, the duration of repolarization is longer than normal. Thus, the QT-interval is prolonged. An interval above 440 milliseconds (msec) is considered prolonged. QT-prolongation in is due to overload of myocardial cells with positively charged ions during ventricular repolarization.

WHAT IS BORDERLINE QT?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
to 470 milliseconds is considered borderline. The average QTc for someone who has long-QT syndrome is 490 milliseconds. A QTc at or above 480 milliseconds in females or 470 milliseconds in males, is probably a sign for long-QT syndrome, in the absence of drugs, electrolyte disturbance, or other conditions that might independently lengthen the QT-interval.

What will the gender ratio be?

WNBR Frequently Asked Questions (FAQ)
While many rides have been gender-balanced, it is rare that females outnumbered males on any ride. Of course we would like it if every mass ride had a good gender balance, but the only people who can help make it happen is the promotion team and the people who show up themselves. One good example of a gender-balanced painted naked cycling group is the painted cyclists of the Summer Solstice Parade in Fremont, Seattle.

WHAT IS THE CORRECTED QT-INTERVAL (QTc)?

QTsyndrome.ch - Frequently Asked Questions (FAQ)
The term "corrected" QT-interval may be misunderstood. It does not mean the measured QT-interval is incorrect, but adjusted for heart rate. The reason is that the QT interval is affected by the heart rate. QTc in concept is best compared to the Body Mass Index (BMI).

Can I get Toxic Shock Syndrome from leaving the DivaCup in for too long?

Lunapads: Frequently Asked Questions about the DivaCup menst...
The DivaCup has not been linked at all to getting Toxic Shock Syndrome. Toxic Shock Syndrome results from a chemical imbalance in the vagina caused by the absorption of vaginal fluids that carry dead cells and other organisms away. Tampons absorb these fluids, disturbing your body's natural cleaning cycle, which is why they put you at risk of Toxic Shock Syndrome and bacterial infections (read the warnings on the side of your box of tampons for more info).
