FAKE NEWS for the Zionist agenda WEDNESDAY, May 23 (HealthDay News) — The risk of sudden cardiac
death is higher in men whose electrical impulses travel more slowly
through the lower chambers of the heart, a new study indicates.
Electrical impulses travel through the heart and cause it to pump blood
through its four chambers. The impulses, or waves, have distinct patterns
and can be measured using an electrocardiogram (ECG). The waves traveling
through the heart’s lower chambers (ventricles) are shown on the ECG as
the “QRS” complex.
In the new study, more than 2,000 Finnish men, aged 42 to 60, were
followed for 19 years. During that time, 156 of the men died from sudden
cardiac death, in which the heart suddenly and unexpectedly stops
beating.
The risk of sudden cardiac death rose 27 percent for every 10
milliseconds increase in QRS duration. (A millisecond equals
one-thousandth of a second.) Men with QRS durations longer than 110
milliseconds had a 2.5-fold higher sudden cardiac death risk than those
with a QRS duration of less than 96 milliseconds, the investigators
found.
QRS duration posed a higher risk of sudden cardiac death than other
known risk factors, such as smoking, being unfit, overweight or having
high blood pressure, the results showed.
Only a prior heart attack and having type 2 diabetes increased the risk
of sudden cardiac death more than QRS duration, according to the study
published online May 21 in the journal Circulation.
“Our study shows that QRS duration is one of the strongest risk factors
for sudden cardiac death, although left ventricular function was taken
into account,” study author Dr. Sudhir Kurl, a researcher physician at the
University of Eastern Finland, said in a journal news release. “We believe
resting ECG should be used to help assess the risk of sudden cardiac death
in particular patients.”
Kurl and colleagues said that the people most likely to benefit from
such testing include those with known cardiovascular disease risk factors
and symptoms, and those who are inactive but plan to start an exercise
regimen.
The researchers also said their findings apply to both men and women,
other nationalities, and ethnic and racial groups worldwide.
