Research on the structure of the heart in different groups of animals includes, among others, the relationships between heart size
and body size (Prothero, 1979; Heusner, 1991; Koritiaki et al., 2013), body performance and the effect of effort or its cessation on the morphological traits of the heart and cardiac contractility (Steel et al., 1976; Nielsen & Vibe-Petersen, 1980; Pape et al., 1984; Gunn, 1989), or the association of heart morphological parameters with various environmental factors (Viscor & Fuster, 1987; Simpson et al., 2007).
The reports pointed out expansion of heart size
due to its thickened muscles while Sharif's echocardiogram (echo) test was also declared unsatisfactory.
Studies of the heart and circulation in disease; Estimations of basal cardiac output, metabolism, heart size
and blood pressure in 235 subjects.
Macaques were chosen because their heart size
and physiology are close to that of humans.
Correlation of cardiac enlargement as assessed by vertebral heart size
and echocardiographic and electrocardiographic findings in dogs with evolving cardiomegaly due to rapid ventricular pacing.
Their study found that losing 510% of body weight was linked to a decrease in heart size
and artery thickness which are both good news for your heart attack risk.
Their study found that losing 5-10 per cent of body weight was linked to a decrease in heart size
and artery thickness - which are both good news for your heart attack risk.
Their study found that losing 5-10% of body weight was linked to a decrease in heart size
and artery thickness -- which are both good news for your heart attack risk.
Among those sampled, abnormal ECG results, as identified by the International Criteria, were more common in older subjects and in those who demonstrated increased thickening of the left ventricular wall relative to their overall heart size
. Athlete body size and race/ethnicity were not associated with the prevalence of abnormal ECGs.
Moreover, due to their small heart size
, selecting pacing lead positions is very difficult in infants.
was normal with low normal qualitative right ventricular systolic function and normal left ventricular size and systolic function.
Cardiac examination showed increased heart size
on percussion and a grade II/VI Levine systolic murmur.
