Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more

What is the difference between "contractility" and "force of contraction" of cardiac muscle?

What is the difference between "contractility" and "force of contraction" of cardiac muscle?

Very complicated: This gets pretty nuanced! Contractility is a concept that refers to the inherent ability for heart muscle cells or the heart in general to develop a certain amount of force for the same given amount of stretch (preload) and load (afterload). Force of contraction is how hard the muscle or the heart is contracting no matter what the loading conditions are. ...Read more

Which layer of heart is affected in heart attack ?

Which layer of heart is affected in heart attack ?

The Inner One: Blood vessels run from the outside of the heart to the inside, so the area that gets hit first is what we call "endocardium" - it's the layer of heart muscle on the inside of the heart chambers. That said, that's only where the damage starts. Depending on the severity of the heart attack, it can involve the entire thickness of the heart wall. ...Read more

What kind of heart palpitations could possibly cause a heavy heart beat and throbbing in the back of the neck? Echo shows Ok heart structure.

What kind of heart palpitations could possibly cause a heavy heart beat and throbbing in the back of the neck?  Echo shows Ok heart structure.

Sorry to frustrate: I know you're asking about cardiac conditions. I don't think it was a mistake to investigate - but it is a mistake to persist if there is a null result - especially at your age. Be reassured. Instead - consider a really skilled Health Psychologist who can teach you how to take your health seriously w/out anxiety and unneeded procedures. It can be the best way to feel better. Worth a try! ...Read more

Is a rapid heart rate one of the symptoms of congestive heart failure or coronary disease?

Is a rapid heart rate one of the symptoms of congestive heart failure or coronary disease?

Not primary symptom: Congestive heart failure may be associated with rapid heart beat but this is not the primary symptom. Rapid heart beat is not usually a sign of coronary artery disease. Rapid heart beat can also occur in otherwise normal hearts. ...Read more

MRI =Mild" thickening of heart muscle not HOCM.Tortuous descending aorta. Aberrant right subclavian artery which courses posterior to the trachea. ??

MRI =Mild" thickening of heart muscle not HOCM.Tortuous descending aorta. Aberrant right subclavian artery which courses posterior to the trachea. ??

Mild thickening's OK: See my comment to your previous post regarding the other findings (tortuous aorta, subclavian artery). The mild thickening of the heart muscle is common, and not necessarily from HCM. It could be the effects of long-standing hypertension. Keeping ur BP low with a -pril or a -sartan (Enalapril, Valsartan, etc.) could even reverse the thickening of the heart. Thanks 4 ur question on HealthTap, & GL! ...Read more

Is a rapid heart rate one of the main symptoms of congestive heart failure?

Can be: Rapid heart rate is definitely one of the constellation of symptoms of untreated heart failure. As the heart weakens, the only mechanism for it to maintain its output is to increase the rate, the feedback mechanisms in the body which dictate more cardiac output lead to the increased heart rate. ...Read more
