An electrocardiogram (EKG or ECG) machine remains necessary in most many medical offices and is absolutely essential for all hospitals. The machine measures the electrical activity present in the heart. The technician attaches several electrodes to the patients body both at the location of the heart in the torso and at the extremities. These electrodes measure when the electrical energy builds up and releases as the valves in the heart tense and relax. This technology not only helps general practitioners identify any chronic problems through a careful analysis, but remains absolutely vital for the life of patients in any emergency medical institution which deals with sever cardiac events. However, it can remain unclear what one should look for when purchasing an EKG.

Ironically, most EKGs are pretty similar when it comes to the core features. One can expect them to read the impulses of the heart clearly and have the ability to print out those readings. In this case, machines which can’t accurately read seldom gain approval from the government. Instead, one should look for a machine which has easy calibration to increase accuracy. One should also check the size of the printer paper along with its cost as that can quickly add up over the life of the machine. However, it’s the secondary features which really separate EKGs from one another.

The secondary features of an EKG can simplify the entire process, save money, and help in the analysis itself. A screen remains the most important secondary feature. It makes it much easier for the technician to get an accurate baseline reading, see the real-time beating of the heart, and immediately visualize any abnormal readings. The ability to connect the EKG to a PC. This allows you to store all the EKG records together without the hassle of paper filing or the coast of buying reams of paper. Finally, it’s often quite helpful to get an EKG with computer memory. This allows you to immediately compare previous scans making it easier to identify any discrepancies.

Smoking is a hard habit to break. There are several products that promise to help people quit, but many people go back to their habit eventually. Whether it is gum or a patch, the use of these sometimes becomes inconvenient while the person still craves the cigarette that they had easy access to before. Something like an e-cig, however, has none of the dangers of the real thing, and also poses no danger to anyone else nearby.

Tobacco smoke has long been known to have many health risks, some that don’t show up for many years or even decades. It does not only affect the smoker, but people who are exposed to the smoke. Those who never smoked themselves can have problems later on if they are regularly exposed. The smell it adds to the breath or even people’s clothes can be very undesirable, and cigarette butts and ashes are quite unsightly when thrown around.

An electronic version tastes and feels like the real thing, without the harmful compounds that are inhaled from regular cigarettes. It looks like the real thing too. While a dose of nicotine is provided with each smoke, there is no smell or a single chemical that is harmful to the person using it or to anyone nearby. You can use at home, at a movie theater, or in clubs while socializing.

Don’t expect this to make you want to quit anymore, but it does have some nicotine to avoid withdrawal symptoms. You will at least have a healthy alternative, and if you like the look of having something to smoke, as some people do, then you can do so without inconveniencing, or even jeopardizing the health of, other people. E-cigs are sold in brands that come in kits with colored cartridges, batteries, cases, chargers and more.

The same technology that brings us computer chips and electronics is also used to improve prescription drugs. Scientists use microfabrication to shrink laboratory experiments and tests onto chips as small as a ladybug. These so-called labs-on-chips are tiny, but they have big implications for the future of medicine.

Computer chips are made by taking a silicon wafer, etching channels for microcircuitry, and coating it with metal to form wires. Successive steps of removing old material and then adding new can make a very complicated circuit. Etching and adding can also be used to make tiny chambers for cells and tiny tubes to add test chemicals. In this way, we can use a microchip both as an electrical device and as an environment for medical testing. Combining electricity, biology, and low cost means that doctors and scientists can perform difficult and expensive electrobiological tests with ease.

A great example of a lab on a chip is the chip-based patch clamp. Before microchip technology, the patch clamp was a wired syringe with an opening small enough to capture just a patch of the cell’s membrane. When a scientist put current through the syringe, she could figure out whether the cell’s membrane was resisting electricity. This helped her to figure out whether the cell was allowing certain chemicals, like calcium ions, to pass through its membrane. Calcium flow issues cause heart problems—this is why the painkiller Vioxx was recalled.

If the cell was immersed in a drug that made calcium pass abnormally, the scientist would find out without endangering patients. But syringe patch clamps are slow—it takes a scientist hours to catch a single cell on the syringe. By contrast, chip-based patch clamps can capture and test 20 cells at once.

By borrowing manufacturing techniques from the computer industry, scientists and doctors are making experiments faster and cheaper—and thus making medicine faster and cheaper for everyone.

These days, technology is changing almost everything, even the ways you can get nicotine. An electronic cigarette is just the latest and greatest when it comes to an old addiction. Who would have guessed that paper cigarettes might become out-dated, not because people decided to get healthy and kick the habit. No, there’s just a cooler way to get your fix. Actually, this invention should not be surprising, since the whole world seems to be going electronic. Even now, most people can’t imagine a world without the Internet, cell phones, or hand held devices. More and more people are finding that their interests and need for information can be met in the palm of their hands–they can socialize, play games, access data, communicate, recreate, and more with just the touch of a few buttons. Now the question is, can people ever stop using electronics or lessen their dependency on them? They are a powerful drug. Some would say they’re more powerful than nicotine. Instant gratification, feedback, and pleasure can all be heady temptations. Things that require work become less tantalizing with the passing of each day. Having the attention span to read a challenging book of 200 pages or so is becoming rare. (Even 200 page books are available on electronic hand-held devices.) Having the energy to run a mile seems like a distant dream. It seems like there are highly addicted people who are zoned out from reality and are tuned in to the virtual world of texting, social networking, watching videos online, and playing computer games. Who knows what kind of world the future will be, whether this trend will continue or whether people will wake up and begin to pull the plug on the electronics that surround them? It’s anybody’s guess, but it looks as if it’s a habit that’s here to stay.

Pacemakers have made rapid advances from their early days. Early pacemakers were large external machines which required a wall socket to be powered. These pacemakers required frequent charging and would cause physical pain through their use. However, modern pacemakers have advanced to provide ease and comfort to patients, but also include a whole host of additional features. Nevertheless, certain features remain important for the treatment of all patients.

Battery life remains the most important part of any pacemaker. The battery remains the primary part to keep the pacemaker going. Pacemakers require service every few months to maintain its battery status. The battery life can last from five to ten years. In this case, one should aim for the highest battery life possible. Pacemakers have advanced to the point that one can have an outpatient surgery to replace the battery, but those who have pacemakers to begin with are often those most vulnerable to infection and complication. Battery life allows both the patient and their health care specialists to cut down on surgeries it proves the number one consideration.

Shielding remains another strong consideration. Early pacemakers were often unshielded. This could lead to death if the patient had even the most minimal interactions with electronic devices. However, current pacemakers have often installed shielding to protect the patient from disruptions. Magnetic fields provide the greatest challenge to electronics. Frequently, magnets leave various electronic components and nothing more than a worthless heap of silicon. However, advances in shielding have created pacemakers that can not only stand up to consumer electronics, but to magnetic resonance imaging machines (MRIs) which create some of the strongest magnetic fields in the Earth. One can help the identification and treatment of other ailments.

Finally, there a host of options which can aid patients above and beyond the core pacemaker statistics. Most newer pacemakers have complex computer systems within them. These complex systems include both information gathering and processing capabilities to keep the pacemaker within the most optimal rate for the heart. They even have pacemakers which can use the phone to call in a status update.
