It is considered an overall measure of cardiac function and is a calculated value as below: cardiac output = heart rate x stroke volume/1000 or CO = HR x SV/1000 Normal range is 4.0 – 8.0 L/min (Source: Inside Surgery) Inside Surgery blogs http://www.medworm.com/rss/comments.php?id=5181679 Fri, 02 Sep 2011 06:00:21 +0100 5181679 http://www.medworm.com/index.php?rid=5103340&cid=t_112913_87_f&fid=39187&url=http%3A%2F%2Fgetbetterhealth.com%2Ftips-to-beat-the-heat%2F2011.08.06 Dehydrated, cramped, limping? on a bike. Road nationals 2010. People who exercise outdoors face a new threat. It’s unrelenting. Consistent. Inescapable. Perhaps, even more dangerous than distracted or mean motorists. It’s the heat. Gosh, is it hot. If only I had a dollar for every time I heard someone say, “Doctor M, you aren’t riding in this heat; are you?” Well…Other than the fortunate souls smart (or lucky) enough to live in cooler climates, most of us are facing an extreme wave of hotness. As a Kentuckian, I live in the epicenter of this summer’s cauldron. Louisville sits in a wind-protected valley alongside the heat sink that is the Ohio River. Think hot and steamy. The excessive heat smacked me hard last evening. Normally, my highly-veined skin and northern European h...

It’s the enemy of creativity, productivity, and, well, sanity. In The Artist’s Way, author Julia Cameron writes: “Perfectionism is a refusal to let yourself move ahead. It is a loop — an obsessive, debilitating closed system that causes you to get stuck in the details of what you are writing or painting or making and to lose sight of the whole.” But you don’t even have to be creating anything to be crippled by perfectionism. It can also frustrate your efforts as a mom, a wife, a friend, and a human being. Because no one and no thing is perfect in this blemished world of ours. I tackle this adversary everyday. And although my inner perfectionist clearly has hold of my brain many days, I do think I am handcuffed less often by the fear of mes...

The Phone Oximeter uses a traditional FDA approved pulse oximetry sensor, but researchers have modified it to interface with a phone, in this case, your iPhone. Currently the setup is being interfaced with an iPhone for trial studies, but is compatible with Android, and other mobile operating systems. What makes the Phone Oximeter special is its ability to capture SpO2 (blood oxygen saturation), heart rate, and respiratory rate — then dynamically comprehend the variables using the decision support software, giving...

Although it’s tempting to reduce patient care to a checklist of “normal” bloodwork targets, we all know that this is only a fraction of the total health picture. Today I made a mistake that brought this truism home: “Don’t treat the number, treat the patient.” I’m turning 40 this year and decided to make an ambitious fitness goal for myself — to be in better shape at 40 than I was at 30. No small feat for a person who used to be in good form a decade ago (not so much now, ahem). So, I joined a gym owned by an affable triathlete and invited her to make me her project.

Consider how the word turbulent is defined: “Characterized by conflict, disorder, or confusion; not controlled or calm.” Those traits don’t sound very heart-healthy. But when it comes to heart rhythm, it turns out that a turbulent response — to a premature beat — is better than a blunted one. The more turbulent the better. No, you haven’t missed anything, and turbulence isn’t another of my typos. Until [recently], heart rate turbulence was an obscure phenomenon buried in the bowels of heart rhythm journals. What Is Heart Rate Turbulence (HRT)? When you listen to the heart of a young physically-fit patient, you are struck not just by the slowness of the heartbeat, but also by the variability...

Total and cardiac mortality rates in Los Angeles County increased after the football team’s 1980 Super Bowl loss but overall mortality fell after the 1984 the team’s Super Bowl win, researchers concluded from a review of death certificates reported in Clinical Cardiology. First, authors gave a clinical review. Stress causes a cardiac cascade. The sympathetic nervous system increases and releases catecholamines. This triggers a rise in heart rate and blood pressure, and ventricular contractility increases oxygen demand, causing blood the sheer against and fracture atherosclerotic plaque, the authors...

For the first time that I can recall, there’s a very helpful article published in Circulation addresses the concerns of implantable cardiac defibrillator (ICD) patients and sexual activity. There’s all kinds of helpful tidbits, like this one: A study of 1,774 patients who had experienced an acute myocardial infarction showed that sexual activity was a likely contributor in fewer than 1 percent of cases. In fact, regular physical exertion, such as that associated with sexual activity, was associated with a decreased risk of cardiac events in patients. Now that’s helpful! Recall that defibrillators are designed to detect rapid, potentially life-threatening arrhythmias. Most of the time, sexual activity does not lead to hea...

A tea made from the plant is used to produce hallucinations, but they can progress to extremely unpleasant experiences. Moreover, Angel’s Trumpet can be deadly, accelerating the heart rate and causing fatal cardiac rhythmic disturbances and bronchoconstriction that can trigger asthma attacks in sensitive individuals.

The mental and physical strength that it must take to complete such a task is mind blowing. I searched around to figure out how the body and human heart can stay strong and continue to beat under such exhaustion. Here is what I found… The researchers found that throughout the course of the races, the runners’ heart rate increased in a very controlled way, which appeared to be scaled to the distance of the race. When the heart rate response was scaled to the proportional distance completed, the results across races of different lengths were virtually identical. These findings support the notion that athletes actively manage the increasing strain on their body, in anticipation of ...

But a new modified version of the popular puzzle game Tetris -- soon be available online -- actually teaches people to calm themselves down to raise their score. The game measures a player's pulse, and if it rises the game speeds up. As the pieces fall faster and faster, players have to calm down and focus to get a higher score.

There is research that shows after just 10 sessions of biofeedback and relaxation therapy, diabetics blood sugars and A1c were lowered and stayed that way for up to 3 months. And a bonus… depression and anxiety among these patients also decreased. Here would be my hunch why this type of treatment could be effective… The Stress Effect Biofeedback may decrease cortisol, a stress hormone linked to insulin resistance. Some of you may remember me writing abo...

The idea behind the fat-burning zone is that if you keep your workout at a moderate level, you'll burn more fat. But if you take your workout up a level of high intensity, you'll burn mostly stored carbohydrates. Fitness experts have long tried to those trying to lose weight in the fat burning zone, but, according to Prevention Magazine those who exercise in the high-intensity zone burn more calories, which they say is more important than burning fat. It's an interesting debate.

Here is some good news that is somewhat related, and may mean that in the future some people will get to avoid surgery: scientists have discovered an enzyme that works to put the brakes on a racing heartbeat. A person's heart rate is set by a single cell within the heart, called the pacemaker cell, and a naturally occurring enzyme called Pak 1 has been found to interact specifically with that cell -- telling it to slow things down.This discovery will obviously have a potentially huge effect on treatments, drugs, and the lives of people living with heart disease.Read | Permalink | Email this | Linking Blogs ...

No? Maybe it's just my gym. But I see them so much that I've started to wonder whether I need one. Heart rate monitors aren't a bad investment, but as fitsugar points out, they're usually more for keeping track of your workout than your heart. You know those heart-rate charts they have all over the gym? Well, in a nutshell, they're telling you what your heart rate should be at depending on what you're aiming for. For cardio-vascular conditioning, your heart-rate should be a bit higher than if, say, you're trying to burn fat. So the heart rate monitor helps you monitor that, and it's a heck of a lot easier than trying to count your pulse while your running o...
