Grounding Transformers Explained
By R. W. Hurst, Editor Grounding transformers are used to provide a path to ground for unbalanced load current and for fault currents on systems where a suitable ground is otherwise not available. Grounding transformers are normally constructed with one of the two configurations: Zig-Zag (Zn) with or without an auxiliary winding or a Wye (Ynd) with a delta connected secondary. The Zig-Zag connection is preferred as it is more cost effective and physically smaller than the Delta-Wye unit.
3 Things Everyone With High Blood Pressure Needs to Know
If you have high blood pressure, you’re probably concerned about getting it under control. And you should be. High blood pressure is a major risk factor for heart disease (the leading cause of death) and stroke (the fourth leading cause of death) and contributes to over 1,100 deaths per day. The more striking aspect is most of these deaths are preventable. We have effective and inexpensive treatments for high blood pressure, yet less than 44% of high blood pressure cases are controlled.
Can Antioxidant Supplements Prevent Heart Disease? The Answer May Surprise You
Do you take antioxidants to prevent heart disease and cancer? Millions of people do. Antioxidants such as vitamin C, vitamin E, selenium, beta-carotene, and coenzyme Q10 are among the most common supplements I see on my patients' medication records. The typical reasons for taking antioxidants include promoting health, slowing aging, and preventing heart disease and cancer. But do they really work? The Antioxidant Story The reasoning behind our enthusiasm for antioxidants makes a lot of sense.
Considering Statins? What a Cardiologist Wants You to Know
Expert Blogs | Heart Health About 35 million people take statins in the United States, but research says only 55% of those who are recommended to take a statin are taking one. This is a big problem because research also shows those at high risk who are not taking a statin have more preventable heart attacks and strokes. Many people who would benefit from taking a statin don’t because they are concerned about the side effects. But does the risk of side effects really outweigh the benefits?

Not All Blocked Arteries Should Be Fixed. Here's Why
If you think all heart artery blockages should be fixed, you’re not alone. For years, cardiologists also thought if we can open a blocked artery with a stent or a balloon, we should. It makes sense, but in some cases, it’s wrong. Let me explain. Doug is a 67-year-old man who came to see me because he feels like he’s a little slower during vigorous exercise than he should be. He doesn’t have chest pain or shortness of breath, and his endurance is good, but he’s not able to keep up as well as he wants.
Should You Be Taking Fish Oil? What a Cardiologist Tells His Patients
Expert Blogs | Heart Health You may have heard that it’s a good idea to take fish oil or another kind of omega-3 supplement for heart health. Many people do – about 20 million people in the US take omega-3 supplements, mostly with the goal of preventing heart attacks and strokes. The question is, are they wasting their money, or getting essential health benefits? The answer may depend on which type of omega-3 they are taking. Are Fish Oil Supplements Good for Your Heart?
Would You Recognize the Symptoms of a Heart Attack?
Someone dies of heart disease in the United States about every 40 seconds. And more than one in three of those deaths occur suddenly – something doctors call “sudden cardiac death.” Here’s why this is important. Most of the people with sudden cardiac death had symptoms in the hours and days before dying; they either just didn’t recognize the signs as worrisome or ignored them.
The effect of New Zealand blackcurrant on sport performance and related biomarkers: a systematic review and meta-analysis
Abstract Background Blackcurrants have come to be regarded as a superfood because of their high polyphenol content, namely anthocyanins. While many berry types have been studied, blackcurrant-anthocyanins may be the superior berry when it comes to athletic performance. The purpose of the review was to evaluate the effects of blackcurrant supplementation on athletic performance, oxidative markers, cognition, and side effects. Methods Systematic review and meta-analysis.
The COVID-19 Risk Factor You Can Control
If you are concerned about your risk from COVID-19, then you should know that there may be significant opportunities to lower your risk beyond hand washing and social distancing. COVID-19 is stabilizing or decreasing in many parts of the world, and this is good news. However, many experts predict the pandemic is far from over, and the worse may be yet to come. The concern is there may be further surges in COVID-19 with the world starting to open.

7 Simple Steps to Avoid a Heart Attack
Expert Blogs | Heart Health Every 37 seconds, someone in the United States dies from heart disease. That’s about 650,000 people a year. And the numbers have been INCREASING every year since 2014. Perhaps even more shocking than those numbers is the fact that this disease, in most cases, is largely preventable – and the steps of prevention really aren’t very complicated. The problem is that most of us just aren’t doing it.
Could COVID-19 Be Causing Strokes? Know the Signs
A new, and frightening, expression of COVID-19 infection has surfaced. Numerous physicians around the world are reporting a possibly increased risk for blood clots in patients with COVID-19. Blood clots (what doctors call thrombosis) are particularly worrisome because of the potential consequences. Blood clots in the veins can travel to the lungs (which is called pulmonary embolus), a potentially life-threatening problem.
Heart Disease and COVID-19: Answers From a Cardiologist
As COVID-19 continues its devastating spread across the country and the world, we are learning new information daily that is important for those with heart disease who want to stay healthy. Of course, following social isolation guidelines and proper hygiene techniques is essential to maintaining your health during this pandemic. However, if you have heart disease or have a loved one with heart disease, there are additional things to consider.
A Cardiologist's Tips for Staying Healthy During the COVID-19 Outbreak
Many of my patients are asking how they can stay healthy in the setting of COVID-19. They are concerned because they have read that those with heart disease, high blood pressure, and diabetes may be at an even higher risk for serious illness from the novel coronavirus (COVID-19, which is also called SARS-CoV-2). And they are right to be concerned.
What This Cardiologist Is Telling His Patients About COVID-19
The COVID-19 coronavirus has turned the world upside down. My heart disease patients are particularly concerned because of reports that they may be at even higher risk. Here are the most common questions I am hearing from my patients and what we know so far. However, I will emphasize that new information is becoming available regularly, and opinions and recommendations are subject to change. I’m concerned about the coronavirus, what are the most important things I need to know?

Do You Need a Stress Test?
When I asked my new patient Steve why he came to see me, he answered, “I think I need a stress test.” It wasn't that Steve had any heart-related symptoms. He had no chest pain or shortness of breath. At 72 years of age, he still exercises vigorously and feels great. However, he’s concerned about heart disease.
What a Cardiologist Eats
“What’s your secret to staying so trim?” The question came from a patient I had been seeing regularly for over 15 years. The painful truth? Not long before then, I had been more than 20 pounds overweight. Although that’s difficult to admit as preventive cardiologist, it was being overweight that set me on the path to my current diet. And my healthier weight. Like many of us, becoming overweight snuck up on me. I grew up thin, but around the time I finished residency, things changed.
How to Lower Your Blood Pressure Without Meds
Expert Blogs | Heart Health High blood pressure is surprisingly common, affecting 46% of American adults – that’s over 100 million people. And it’s a serious threat. High blood pressure increases the risk for heart attack, heart failure, stroke, kidney failure, and several other life-threatening health problems. In fact, high blood pressure causes about 1,000 deaths in the U.S. PER DAY. Even more disturbing is that most of these deaths are preventable.
Industry Voices-We could be getting blood pressure readings wrong. This program aims to change that
For most of my career as a cardiologist, I’ve failed to take patients’ blood pressure readings in the most accurate way, and so have most healthcare providers. Measuring blood pressure is usually the first thing that we do in an office visit. But now that researchers are examining the process more closely, we are learning that these readings are often inaccurate—as much as 60% of the time—and can significantly undermine treatment decisions.
Is Alcohol Really Good for Your Heart?
You’ve probably heard in the media, and maybe from your doctor, that a “moderate” amount of alcohol is good for your heart. But more recent research has called that into question. In fact, this new information has made me re-think the way I talk to my patients about alcohol and heart health. Alcohol and Heart Disease The research on alcohol and its effect on our health has limitations.
How to Get a Handle on Your High Blood Pressure
High blood pressure is a condition that patients tend to dangerously underestimate – many people just don’t take it very seriously. But they should. It’s a leading cause of death and disability; in fact, it’s been estimated that high blood pressure is a primary or contributing cause of over 400,000 deaths per year – that amounts to more than 1,100 deaths per day. So why aren’t we more afraid of it? I think the answer is a mix of familiarity and treatability.
Why High ‘Good’ Cholesterol Is No Guarantee Against a Heart Attack " Heart Health
“You’ll never have a heart attack.” Jane heard this from several doctors over the years. Why? Because Jane had a very high HDL cholesterol level (171 mg/dL). HDL is often referred to as the “good cholesterol” because high levels are considered to be protective against heart attack. Yet, despite doctors’ reassurances that her HDL would protect her, Jane was still concerned about her heart disease risk. And rightly so. Jane was 61, and she felt great.
Should You Be Taking a Daily Aspirin?
“I should be taking aspirin, right?” Jeff, a 60-year-old patient, wants to make sure he’s doing everything he can to guard himself against a heart attack. Though he doesn’t have a history of heart disease, he does have risk factors, including high blood pressure and high cholesterol, so he’s wise to stay vigilant.

Think You’re Safe From Heart Disease? " Heart Health
Rob Steinberg never thought he would have a heart attack. Or, at least, not at 45 years old – and certainly not when he was in the best shape of his life. Rob had completed his 3rd Ironman triathlon, finishing near the top of his age group, and was training for his 4th. Focused on trimming critical minutes off of his time, he noticed his throat felt very dry during strenuous parts of his training. He ignored it for a few weeks, but the sensation wasn’t going away; in fact, it was getting worse.
7 Simple Steps to Avoid a Heart Attack

Heart Disease: Getting Serious About Prevention « Heart Health
By John Mandrola, MD Here’s one more way men and women are equal: neither sex should have heart disease. New data: Last year, Finnish investigators showed that 4 of 5 heart attacks in men could be avoided. All the men had to do were five things: be modestly active, eat a good diet, not smoke, drink alcohol moderately and maintain a normal body weight. The findings of this robust study made an impression on the cardiology community. But it was a study of just men.
