Question 1

is the heart doing the most of its work during systole?

Accepted Answer

Yes: Most muscle energy would be expected to be expended  during systole.

Question 2

why does end-systole volume (esv) changes with exercise?

Accepted Answer

This is a: physiological adaptation to improve cardiovascular performance as the heart rate increases. It is mediated through catecholamine effects.

Question 3

just woke up and it felt like my heart was beating very strangely, equally spaced out systole/diastole, could hear both "beats" clearly. what was this?

Accepted Answer

Possible bigeminy.: When premature beats occur frequently so they form every other beat, it's possible to feel as though one is experiencing a pause every other beat; it might be that the sensation you describe is this phenomenon.  Ones doctor can often hear the pattern by listening to ones heart.  In addition, an ekg and holter monitor test might be needed for accurate diagnosis.

Question 4

what does the aortic valve do during systole?

Accepted Answer

Open: The aortic vave is open during systole allowing blood to be ejected from the heart.

Question 5

is left ventricular wall thickness measured by echocardiogram using values from systole or diastole?

Accepted Answer

: I have seen left ventricular wall thickness measured in both systole, at end -diastole&amp;,at mid-diastole   However these readings can underestimate or overestimate and determination of ventricular mass is a much more accurate.assessment.

Question 6

what's missed beat called on the heart? is heart extra systole? whether missed beat can be syndrome sick sinus?

Accepted Answer

Needs holter: everyone has some minor arrhythmias. So, the risk of serious problems is statistically low.
BUT, cannot say in your particular case, and an EKG followed by a holter to see the exact pattern is necessary.

Question 7

hyperkalemia causes cardiac arrest in systole?

Accepted Answer

No: Hyperkalemia causes cardiac arrest in diastole.

Question 8

on echo lvid(diastole) is 5.2 cm with normal limits less than 5.7 cm, and lvid(systole) is 3.7 cm with normal limits less than 4 cm. according to the above data is left ventricular size normal (in senior citizens)? thanks?

Accepted Answer

: I believe that these measures of left ventricular diameter indicate that your left ventricle is of normal size and function. Did the echo report mention any concentric hypertrophy? Your physician or cardiologist who received the entire report can advise you best.

Question 9

in heart auscultation the sound coinciding with radial pulse is the sound during the heart's systole, is that correct?

Accepted Answer

First Heart Sound: or S1 is the sound of the atrioventricular valves closing for systole and usually coincides with the radial pulse. S2, (racepinephrine) the second sound is the closing of the aortic and pulmonic valve and indicates diastole. Thanks for trusting HealthTap!

Question 10

greetings doctor .... i have repeated episodes of extra systoles followed by sinus tachycardia several times a day ... at the same time i am suffering?

Accepted Answer

NeedCardiacEvaluatio: Repeated episodes of extrasystolies getting several times a day needs Cardiac Evaluation.A detailed History including history of smoking and any other medical condition,caffeine intake and complete examination and Ekg.24 hour Holter Monitor.Ech cardiogram.And if indicated Stress Test/Coronary Angiogram.We don't know your age.Consult a Cardiologist
