I remember reading something about "over a year" when I thought people who got heart transplants could live for as long as normally healthy people. What happens after a while? Does the body start rejecting the new heart? Does it not last as long? Why do people with a new heart still die early?

Patients who recieve transplants have to take anti-rejection medication for the rest of their lives. These meds don’t work forever in all patients, and then the body may attack the transplanted organ. People with new hearts have to care for their bodies very well and follow up closely with the doctors. They can live up to normal life expectancy and are able to do almost anything, but usually if they needed a heart transplant, that’s not the only issue with their health.
What you might have seen with the "one year" issue is that the transplant is considered "successful" if the patient lives a full year after the transplant… in other words, having the transplant did not kill them, their body has ‘accepted" the new organ and it is working well.

I need to know because I have few, but very strong heart palpitations nearing a climax which made me stop all sexual activity.

Is that the "He’s home early" syndrome? LOL

Seriously, that’s worth a doctor’s appointment regardless of what activity started it.

Taken from Burt Sugarman’s The Midnight Special show aired in 1976.

Ann Wilson had (has) one of the finest voices in rock history (my opinion anyway), and sister Nancy sure could play that guitar…

A lot of people are remarking that Roger Fisher is looking like Luke Skywalker, but remember this clip is from 1976 while the first Star Wars movie is from 1977… Who is posing who I might ask?

For example my heart beat went from 120-160 in seconds whilst I was in hospital which is a pretty big gap – and it was really irregular, I had an injection to regluate it. Anyone else had a heart beat thats been really irregular?
Just wondered what is the MOST irreglar heart beat because surely if your heartbeat becomes too irregular wouldnt it class as heart failure and you would die?

The most irregular heart beat I had was 211 beats per minute. Thank goodness I was in the ER when this event happened, had a early event in the morning at home. Now have a heart failure pacemaker/defibrillator.

If the systolic is the product of heart contraction how can a relaxed heart squirt blood throughout the circulatory system? Why does a pressure (Diastolic) is the result of a non motion action (relaxed heart) Not even my teachers can explain this.They ‘ve been taught the way it is but they can’t explain why there’s still blood moving (blood pressure) between heartbeats. Please help!

So your right, the systolic is the number in which the amount of pressure is in the artery of the heart during contraction. Diastolic however is the minimum pressure reading which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. Diastolic is not based on the contraction of the beat, although the heart is relaxed its still working as it refills with blood, in return is where you obtain the minimum pressure in the heart when this occurs.

Don’t you want someone
To care about you?
What about love?
Don’t let it slip away
What about love?
I only want to share it with you
You might need it someday”

Resumindo mesmo: ainda há muita coisa a descobrir!

I understand that a higher heart rate means a higher workload for your heart. I have a fairly low resting heart rate (mid 50’s) and am active, so how does this compare with someone who is less active with a higher resting heart rate with the same weight/height ratio? Thanks for any input!

Nearly every time you pick up a magazine or newspaper these days, you see advertisements for products that supposedly raise your metabolism. Whether they’re trying to sell you exercise equipment or food supplements, these ads claim that the products turn up the heat in your body so you burn more calories even when you’re not exercising. Sounds logical enough, but is it true?
No question, in today’s fitness world people are mad for everything metabolic. But what exactly is this thing called "metabolism" and how much do we really know about raising it? For example, what’s better for the boost- weight training or aerobics? And is it true that eating hot chili peppers fires up your rate of fat combustion? Here are some burning questions about burning calories, plus some answers that are sure to surprise you.

What does "metabolism" mean?
Your metabolism is the sum of processes involving energy production- specifically, the chemical changes in your living cells by which energy is provided for your vital processes and activities and new material is assimilated. You can also think about your metabolism as the number of calories you’re burning at any given moment, whether you’re watching "Seinfeld" or pumping away on the StairMaster. Naturally, your metabolic rate- the rate of energy production and expenditure- will be higher when you’re exercising than when you’re crashed on the couch.

Will aerobic exercise raise your resting metabolic rate?
Several studies have failed to show any significant increase in resting metabolic rate due to aerobic workouts. One, for instance, found that men who jogged three times a week for 30 minutes at about 70 to 80 percent of their maximum heart rate did not increase their RMR. But they were certainly burning lots of calories on the run.

What is "afterburn"?
This term refers to the fact that your metabolic rate stays elevated after you do any kind of exercise. But the effect varies greatly depending on the type of workout, how hard and, to some extent, how long you just exercised.
In a recent study, Christopher Melby, Dr.P.H., associate professor of nutritional science at Colorado State University in Fort Collins, and his colleagues monitored seven men who did a killer, 90-minute weight workout- six sets of 10 exercises with very little rest between sets. Two hours after the workout, their metabolic rate was 11 percent higher than normal. When the subjects were measured the next morning, 15 hours after the workout, their metabolism was still elevated by a hefty 9 percent, which could translate into as much as 150 extra calories burned.
In another study, Melby cut the workout down to five sets of each exercise and let the subjects rest longer between sets. The subjects’ post-exercise metabolic rate also was 11 percent elevated after two hours; but by the next morning, the increase had dropped to less than 5 percent. "What that indicates is, the post-exercise metabolic rate [of a weight-training workout] is a function of exercise intensity primarily, and to some extent duration," Melby says. The numbers in both studies were impressive, but the workouts were far longer and more strenuous than most people have the time, strength, stamina and motivation to maintain. Melby believes that the concept of afterburn gets too much hype. After all, the calories you burn post-exercise are negligible compared to what you burn during the workout.

Does aerobic exercise also give you an afterburn?
Yes, but it probably doesn’t last as long as the weight-training afterburn- unless you work out intensely or do interval training. Most studies have found that mild to moderate exercise elevates metabolic rate for only a few minutes to a few hours. If, for instance, you jogged at 70 percent of your maximum heart rate for a half-hour, you probably wouldn’t experience an afterburn for more than an hour. "For most people it’ll be less than that," Melby says, burning no more than 15 to 30 calories. On the other hand, highly trained athletes who can run for, say, 90 minutes at 75 percent of their maximum heart rate, might have significant afterburn for several hours. The bottom line: Focus on burning calories during your workout, not after.
As for why strength training has more of an afterburn than moderate aerobic exercise, scientists aren’t sure. One possible explanation, Melby says, is that anaerobic exercise, such as weight training, might elevate levels of the hormone epinephrine, which stimulates metabolic rate. Another theory: The repair of microscopic tissue damage caused by weight lifting might expend more energy.

What about aerobic interval training?
Go for it. Afterburn seems to depend mainly on workout intensity (duration doesn’t have nearly as much effect). So if you do aerobics, interval training with alternate bursts of activity will get the best post-workout rise out of your metabolism. "If you did a number of short bouts, say on the treadmill or the bike, at 95 percent of your max, the afterburn would be significantly greater than if you used the same number of calories, or even more, doing one longer, lower-intensity bout at 50 or 70 percent of your max," says Melby. "Your metabolic rate would be elevated for a longer period at a higher magnitude."
So there is truth in advertising. Some kinds of equipment can rev up your body’s calorie-burning rate; just be sure to do high-intensity interval training for the best metabolic results.

Is there any way to lower metabolism?
Yes. Go on a very low-calorie diet. Your body will sense that it is being starved and will fight back by slowing down. "If you don’t get enough calories, your metabolic rate can go down profoundly, says Callaway. Severely anorexic women, he says, burn 30 to 40 percent fewer calories a day- sometimes 50 percent- than women who eat normally. (In other words, an anorexic who takes in only 200-300 calories a day uses it up much more slowly that her normal counterpart.) It’s not clear how much of a calorie deficit triggers a drop in RMR- there’s probably a continuum. But, says Callaway, you can get into trouble by consuming fewer calories than your RMR requires.

Can’t you prevent your resting metabolism from dropping by exercising when you diet?
Not necessarily, especially if you’re on a very low-calorie diet. Two late-breaking studies divided subjects into four groups: diet only, diet plus aerobic exercise, diet plus weight training, and diet plus aerobics and weight training. After many weeks, After many weeks, both studies found no significant weight loss among any of the groups. "When you add a lot of exercise on top of a marked caloric restriction, you’re not going to prevent resting metabolic rate from falling," says Thomas A. Wadden, Ph.D., a psychology professor and director of the weight and eating disorders Program at the University of Pennsylvania School of Medicine in Philadelphia who conducted one of the studies.
That doesn’t mean you should skip the exercise. To the contrary, you should diet and work out with moderation. In Wadden’s study where the diet was severe- 128 obese people ate only 925 calories a day for the first 16 weeks and 1,500 daily for the next 32- there were no significant differences in weight or body composition changes among the groups. (Both calorie amounts were severe for this population.)

From their 1985 self titled album the video for “These Dreams”

Spare a little candle, save some light for me. Figures
Up ahead moving in the trees. White skin in linen,
Perfume on my wrist, and the full moon that hangs over
These dreams in the mist.

CHORUS
These dreams go on when I close my eyes. Every second
Of the night, I live another life. These dreams that
Sleep when it’s cold outside, every moment I’m awake,
The further I’m away.

Is it cloak and dagger, could it be Spring or Fall?
I Walk without a cut through a stained-glass wall.
Weaker in my eyesight, a candle in my grip, and words
That have no form are falling from my lips.

CHORUS
These dreams go on when I close my eyes. Every second
Of the night, I live another life. These dreams that
Sleep when it’s cold outside, every moment I’m awake,
The further I’m away.

BRIDGE
There’s something out there I can’t resist. I need to
Hide away from the pain. There’s something out there
I can’t resist.

The sweetest song is silence that I’ve ever heard.
Funny how your feet in dreams never touch the Earth.
In a wood full of princes, freedom is a kiss. But the
Prince hides his face from dreams in the mist.

CHORUS
These dreams go on when I close my eyes. Every second
Of the night, I live another life. These dreams that
Sleep when it’s cold outside, every moment I’m awake,
The further I’m away.

CHORUS
These dreams go on when I close my eyes. Every second
Of the night, I live another life. These dreams that
Sleep when it’s cold outside, every moment I’m awake,
The further I’m away.
