A few times a month, at least one or two patients in cardiologists’ Pikesville and Baltimore, Maryland practices bring in their smartwatch or smartphone with ECG data. In these cases, the wearable has a single-lead ecg that captures and stores a recording when the user places their finger or fingers on sensors. This data can then be viewed on an app.

ECG, or electrocardiogram, is a medical test that shows how your heart beats by measuring and recording the electrical activity of the cardiac cells (which create the signals that cause each beat). The results are usually displayed electronically or printed on paper. Health practitioners can use the resulting trace to look for various conditions, including arrhythmias like atrial fibrillation and coronary artery disease.

A Doctor’s Perspective: How ECG Devices Improve Diagnosis and Treatment

The most common way a physician takes an ECG reading is with a machine that requires you to lay down on a table while small sticky dots (electrodes) and wire leads stick to your chest, arms, legs and feet. The device then records the electrical activity and sends the information to a computer that displays it on screen or prints it out. The resulting trace can indicate things like your heart rate, the strength of the signal, and whether your heartbeat is regular or irregular.

Portable ECG machines are useful in identifying certain arrhythmias, particularly those caused by long QT syndrome (LQTS). They can also be helpful for monitoring a serious condition known as ST-elevation myocardial infarction, or STEMI, which is typically brought on by exercise and can lead to sudden cardiac arrest or death.

The advantage of solar energy is a clean, renewable energy source that doesn’t produce any greenhouse gases during its production process. It also saves homeowners money on electricity costs, reduces reliance on the grid, and contributes to environmental sustainability.

The sun’s endless supply of energy is a resource that can be harnessed in a variety of ways to generate power for homes and businesses. The two primary types of solar energy are photovoltaics and concentrated solar-thermal power. PV cells convert sunlight into electrical energy, and CSP uses mirrors to concentrate solar radiation for heat generation.

As more and more homeowners go solar, they’re finding new reasons to love their panels. Solar panels provide a steady stream of free power, significantly reducing monthly utility bills and increasing home values. Plus, they help to protect against rising electricity rates and grid instability.

Harnessing the Power of the Sun: 5 Key Advantages of Solar Energy

Solar energy has the potential to drastically improve the quality of life for millions of people who do not have access to a stable, affordable power source. These people rely on fuel-based lighting, which causes significant health and productivity costs. Unlike traditional power sources, solar energy can be produced locally, allowing for more security and independence.

The best way to maximize solar power efficiency is to change your energy-use habits during the day. For instance, use a solar water heater instead of a conventional one. Also, limit the number of appliances running at the same time and replace incandescent light bulbs with LED or CFL bulbs, which use up to 80% less energy. Lastly, invest in high-quality solar panels that feature anti-reflection coatings and a textured surface to increase their energy efficiency.
