Each row has 6 seats (except for the row 28, with only three) and an aisle down the middle. That makes 55 aisle, 55 middles and 55 window seats. Odds are, only a third of the plane has the seats you want, and thatâs without considering everyone else youâre flying with. If youâre an elite flyer, youâre in luck. We hold some seats for you, because we appreciate your loyalty and want to show our gratitude.
Congestive Heart Failure. Congestive heart failure (CHF), or heart failure, is a condition in which the heart can't pump enough blood to the body's other organs.
We consider a heart to be mildly weak if the ejection fraction is 40% â 50% on a MUGA, or 45% to 55% on an echocardiogram. We consider an ejection fraction of 30%-40% on MUGA or 30% â 45% on an echocardiogram to be a moderately weakened heart muscle.
