“…1 Congenital LQTS is an important and previously underestimated cause of sudden death in young people. 2 It can be inherited as an autosomal dominant (Romano Ward syndrome) or autosomal recessive (Jervell and LangeNielson syndrome) condition. Drugs, electrolyte imbalances and some neurological, cardiac and metabolic conditions can precipitate acquired LQTS.…”

“…Perhaps surprisingly, and maybe for methodological reasons, few studies have related the mean Q-T interval to outcome [5]. However, the data presented here suggest that lead V 3 and lead II are acceptable substitutes for the mean Q-T interval, and there are several studies relating these leads’ Q-T interval to prognosis [6].…”

Which Lead for Q-T Interval Measurements?

There are several Q-T interval measures (individual lead, mean Q-T interval or Q-T dispersion) from a 12-lead ECG. Which should be used? As the ECG provides twelve different measures of the heart’s ‘true’ Q-T interval, and as, ‘a priori’, no one measure is any better or worse than any other measure at estimating the ‘true’ Q-T interval, the best measure is the average of these twelve measures, i.e., the mean Q-T interval. The best single lead to measure the Q-T interval is the lead that relates most closely to the mean Q-T interval which in 49 subjects with cardiac diseases was lead V₃, then lead II. The longest lead Q-T interval relates poorly to the mean and to the individual lead Q-T intervals and therefore carried information different to and quite unique from these measures. This unique information is Q-T dispersion which relates well to the longest lead Q-T interval (r = 0.71, p < 0.001).

Sudden unexpected nocturnal deaths among Thai immigrant workers in Singapore

Sudden Unexpected Nocturnal Deaths (SUND) occur in young, apparently healthy immigrant workers from Thailand, the Philippines and Bangladesh living among ex-patriot labour forces in countries such as Singapore and Saudi Arabia. Several factors associated with these deaths are similar to those observed for Sudden Infant Death Syndrome (SIDS): sleep related and mainly nocturnal occurrence; no prodromal illnesses other than mild respiratory tract infection; exposure to cigarette smoke; absence of invasive microorganisms at autopsy. The hypotheses proposed to explain these deaths in adults are examined. Based on our studies of the role toxigenic bacteria might play in some cases of SIDS, we suggest a new approach to the investigation of SUND.
