The murmur from HOCM is from the mitral valve leaflet jamming into the septum, also called systolic anterior motion (SAM). This disappears when you increase the volume of LV because if you increase the volume, the ventricle becomes more distended and the leaflet is further away from the septum, so you have less murmur that can be heard.
MVP murmur decreases ...
In children, right atrial thrombosis is associated with placement of a central venous catheter.
Berman W Jr, Fripp RR, Yabek SM, Wernly J, Corlew S. Great vein and right atrial thrombosis in critically ill infants and children with central venous lines. Chest. 1991 Apr;99(4):963-7. PubMed PMID: 2009803.
For calculation of Bp and CO,
Bp = CO * TPR
CO = SV * HR
Where tpr is total peripheral resistance, HR is heart rate(bpm), SV is stroke volume
SV = End diastolic vol - end systolic vol
Now, there isn't any direct graphs for relation between BP and SV, theoretically we can see BP varies linearly with SV. However more important are changes which are ...
Your understanding about the mechanism by which the K+ ions leak out of the cardiac cell during ischaemia is correct.
But, regarding the latter part, lets discuss what is the situation of K+ ions in a normal cardiac cell.
In a normal cardiac cell, the concentration of K+ ions is more inside compared to the outside of the cell (150mM inside as compared to 4mM ...
Intense cardio training over sufficiently prolonged time tend to incerease the capacity of your cadiovascular system to carry oxygen to the muscle. One aspect (among many) is the increase in volume of the left chamber of the heart which is seen in professional athletes of enurance sports.
Blood pressure ...
While you seem to be asking several questions in this thread, I will try to answer them as well as I can.
Is chronic fatigue syndrome a symptom of myocarditis?
No, chronic fatigue syndrome can not be a symptom of myocarditis because CFS is a specific, separate medical condition that is pathophysiologically understood to be neurological, immunological, or ...
Unlike atrioventricular valves, semilunar valves' leaflets are concave, somewhat like shallow bags, which, during the diastole are filled with blood and therefore are pushed back to touch one another and so close the valve opening.
a good gif to visualise.
