Bradycardia, also known as bradyarrhythmia, is a slow heart rate, namely, a resting heart rate of under 60 beats per minute (BPM) in adults.It is a type of cardiac arrhythmia. It seldom results in symptoms until the rate drops below 50 BPM.
Bradycardia can cause dizziness, weakness, lack of energy or fainting spells.If bradycardia is caused by a medical illness, there will be additional symptoms that are specific to that illness. For example, people whose bradycardia is due to severe hypothyroidism also can have constipation, muscle cramps, weight gain (often despite poor appetite), very dry skin, hair that is thin and dry, an abnormal sensitivity to cold temperatures and other symptoms related to low levels of thyroid hormones.
Patients are test driving a pacemaker outside the skin before deciding whether to have a permanent implant, reveals novel research presented today at EHRA EUROPACE - CARDIOSTIM 2015."Patients have numerous concerns, such as body image issues. There will be an incision in the upper chest, perhaps some discolouration of the skin and a lump which may be visible depending on what you wear. In women there are intimacy issues with upper chest device implants and usually consider a submammary location.
A World Health Organization study found a 10-fold variation in the age-adjusted annual incidence per 100 000 in Finland. A later systematic review supported a high incidence of aSAH in Finland and Japan, a low incidence in South and Central America, and an intermediate incidence of 9.1 per 100 000 population in other regions. In a more recent systematic review of population-based studies, the incidence of aSAH ranged from 2 to 16 per 100 000.5 In that review, the pooled age-adjusted incidence rate of aSAH in low- to middle-income countries was found to be almost double that of high-income countries. Although some reports have suggested the incidence of aSAH in the United States to be 9.7 per 100 000, the 2003 Nationwide Inpatient Sample provided an annual estimate of 14.5 discharges for aSAH per 100 000 adults. Because death resulting from aSAH often occurs before hospital admission (an estimated 12% to 15% of cases) the true incidence of aSAH might be even higher. Although a number of population-based studies have indicated that the incidence of aSAH has remained relatively stable over the past 4 decades,5,10–16 a recent review that adjusted for age and sex suggested a slight decrease in incidence between 1950 and 2005 for regions other than Japan, South and Central America, and Finland These data are consistent with studies that show that the incidence of aSAH increases with age, with a typical average age of onset in adults ≥50 years of age.3,7,17,18 aSAH is relatively uncommon in children; incidence rates increase as children get older, with incidence ranging from 0.18 to 2.0 per 100 000.4,19 The majority of studies also indicate a higher incidence of aSAH in women than in men.7,11–13,20–22 Most recent pooled figures report the incidence in women to be 1.24 (95% confidence interval, 1.09–1.42) times higher than in men.4 This is lower than a previous estimate of 1.6 (95% confidence interval, 1.1–2.3) for the years 1960 to 1994.23Evidence of a sex-age effect on aSAH incidence has emerged from pooled study data, with a higher incidence reported in younger men (25–45 years of age), women between 55 and 85 years of age, and men >85 years of age.4 Differences in incidence of aSAH by race and ethnicity appear to exist. Blacks and Hispanics have a higher incidence of aSAH than white Americans.6,24,25
