How Much Heart Rate Variability Is Normal?: Each person has their own distinctive heart rate variability (HRV), which cannot be measured against a chart, range, or averages. A person’s HRV can change from day to day and from season to season. A person’s age, gender, and even circadian rhythm can affect HRV.

Heart Rhythm Disorders

Arrhythmias or heart rhythm disorders are conditions that causes changes in the normal heartbeat. There are numerous types of arrhythmias, for example, supraventricular tachycardia, sinus sick syndrome, atrial fibrillation, atrial flutter, and ventricular fibrillation. Signs and symptoms of an arrhythmia may include: Chest pain or discomfort Shortness of breath Palpitations Racing heart sensation Treatment for arrhythmias depend upon the cause.
Heart Attack Symptoms or Hiatal Hernia Differences

A heart attack happens when a blood clot blocks a blood vessel in the heart, which causes heart muscle death. A hiatal hernia is a GI tract problem that occurs through the opening of the diaphragm where the esophagus meets the stomach. When the muscles surrounding the diaphragm become weak or damaged, the upper portion of the stomach protrudes through the opening of the diaphragm. Both a heart attack and hiatal hernia can cause the same symptoms of chest pain that radiates down the arm, back, and neck, they are not the same. Heart attack is a medical emergency while a hiatal hernia usually is not. Heart attack symptoms that do not occur with a hiatal hernia include shortness of breath with chest pain that feels tight, full, achy, or pressured, heart palpitations, and jaw ache. Heart attacks in women also cause symptoms of extreme weakness and fatigue. Hiatal hernia symptoms that are different from heart attack are severe heartburn, belching, indigestion, coughing, problems swallowing, hiccups, and upper abdominal pain. Both heart attack and hiatal hernia may be preventable diseases. Heart attack is a medical emergency. Call 911 of you think you or someone you are with is having a heart attack; even if you think it may be heartburn or indigestion.
Chest Pain on a Plane Heart Attack

A harrowing airplane journey across the Atlantic demonstrates what doctors do in the event of a heart attack in mid-flight.
Congestive Heart Failure

Congestive heart failure (CHF) is a condition in which the heart can't pump enough blood and oxygen to the body's tissues. Learn about symptoms and treatment.
Checkup

Some people expect to have a yearly medical checkup, and others feel that a checkup once every two to three years is sufficient. In the past, most medical groups advocated an annual health exam. However, more recently, the American Medical Association and other similar groups have moved away from the yearly exam.
Understanding Heartburn/GERD Medications

GERD and heartburn medications include: antacids, histamine-2 blockers, proton pump inhibitors (PPIs), coating drugs, and promotility drugs. Side effects, drug interactions, and patient information should be reviewed prior to taking any medication.
Heart and Lung Transplant

Heart-lung transplants are indicated when the heart is unable to pump blood to all the organs of the body and does not respond to other medical or surgical treatments. Patients with end-stage heart failure who receive a heart-lung transplant must be on immunosuppressive drugs for the rest of their lives.
Heart Attack

A heart attack is an interruption in blood flow to the heart muscle. Arterial plaque rupture is often the cause of a heart attack. Symptoms of a heart attack may include chest pain, shortness of breath, sweating, and nausea. Emergency heart catheterization and thrombolytic therapy may be used to treat a heart attack.
Heart Attack Symptoms and Signs

The heart is a muscle like any other in the body. Arteries supply it with oxygen-rich blood so that it can contract and push blood to the rest of the body. When there isn't enough oxygen flow to a muscle, its function begins to suffer. Block the oxygen supply completely, and the muscle starts to die.
Coronary Heart Disease

Coronary heart disease (CHD) is a group of different types of heart disease. Symptoms of heart disease depend on the cause and inclue chest pain or angina, shortness of breath, palpitations, and dizziness. Many conditions causes heart disease, for example, genetics, obesity, high cholesterol, and smoking. Treatment for heart disease depend on the cause and include diet and other lifestyle changes, medications, procedures, and surgery. The prognosis (outlook) and life span for someone with heart disease varies depending on the cause.
Heart Failure Symptoms

Heart failure is an inability of the heart to pump blood adequately. Early symptoms and signs of heart failure include shortness of breath, peripheral edema, exercise intolerance, weight gain, increased urination, fatigue, pleural effusion, and paroxysmal nocturnal dyspnea.
Heart Tumors in Children

Most tumors that form in the heart are benign (not cancer). Heart tumors that may appear in children include 7 different types. Before birth and in newborns, the most common benign heart tumors are teratomas. An inherited condition called tuberous sclerosis can cause heart tumors to form in a fetus or newborn.
Congestive Heart Failure Survival Rate

The life expectancy for congestive heart failure depends on the cause of heart failure, its severity, and other underlying medical conditions.
How Serious Is an Irregular Heart Beat

There are a number of causes for an irregular heartbeat. Sometimes, irregular heartbeat (arrythmia) is a relatively benign condition. In other contexts, irregular heartbeats may be the precursor to a heart attack or an indication of some other serious problem.
How Serious Is Heart Ablation Surgery?

Cardiac (heart) ablation is a minimally invasive procedure that uses radiofrequency energy to destroy small areas of heart tissue that cause irregular heartbeats. In general, cardiac (heart) catheter ablation is a minimally invasive procedure and risks and complications are rare. When the procedure is done as part of a larger, open surgery, however, you need time in an ICU and at least a week in the hospital.
Is Takotsubo Cardiomyopathy A Heart Attack

Takotsubo cardiomyopathy is not a heart attack. Takotsubo cardiomyopathy, also called stress cardiomyopathy or "broken heart syndrome," is a heart condition that causes sudden and temporary chest pain, difficulty breathing, and lightheadedness and fainting. It commonly occurs in older women and may be triggered by intense emotional or physical stress such as the death of a loved one (this is why it’s sometimes called broken heart syndrome), an acute illness, or even a stressful argument.
Staying Up to Date Heart Attack Guidelines

Medical conferences help keep doctors up-to-date on the latest best medical practices, such as heart attack guidelines.
SVT Supraventricular Tachycardia vs Heart Attack

Supraventricular tachycardia (SVT) is a rapid heart rate that affects the upper ventricles of the heart. In contrast, a heart attack is a severe reduction or complete blockage of blood to one or more segments of the coronary arteries that can cause death of heart muscle.
What a Heart Attack Really Feels Like

Symptoms of a heart attack include chest pain that is sudden, feels like a squeezing or fullness, feels like mild chest pressure or discomfort, feels like heartburn, lasts for more than a few minutes, or may go away and come back. It can also involve pain, tingling, or discomfort in other areas of the body.
What Are Four Common Types of Heart Disease

Coronary artery disease, arrhythmia, heart valve disease and heart failure are the four most common types of heart disease.
What Are Signs Your Heart Is Quietly Failing

Heart failure is what happens when the heart fails to pump and cannot circulate oxygen-rich blood throughout the body normally. Warning signs and symptoms of heart failure include shortness of breath, chronic coughing or wheezing, swelling, fatigue, loss of appetite, and others.
What Are Target Heart Rates Chart

A target heart rate refers to what your heart rate should be while doing exercise, while a resting heart rate is the number of beats per minute (bpm) when at rest. An adult’s target heart rate is calculated based on their maximum heart rate, which is calculated based on a person’s age.
What Are First Signs of Heart Attack in a Woman

Symptoms of a heart attack that tend to happen more often in women than in men include shortness of breath, nausea, vomiting, dizziness, lightheadedness, extreme fatigue, back or jaw pain. If you think you might be having a heart attack, call 9-1-1 immediately.
What Are the 4 Stages of Congestive Heart Failure

The four stages of heart failure are classified by the letters A, B, C and D. “A” is the least severe stage with no symptoms, and the scale progresses to “D,” the most severe, requiring aggressive medical treatment.
What Are the Signs of An Impending Heart Attack

A heart attack, also called myocardial infarction (MI), happens when the blood flow from the coronary arteries to the heart is reduced or blocked completely. When this occurs, it starves the heart muscle of oxygen and nutrients, resulting in damage to the heart and potential death.
What Are the Silent Signs of a Heart Attack

When blood flow from the coronary arteries to the heart is reduced or blocked completely, this causes a heart attack (myocardial infarction or MI). Silent symptoms of a heart attack include mild chest pressure or discomfort, shortness of breath, dizziness or lightheadedness, nausea, cold sweats/clammy skin; and pain, tingling, or discomfort in one or both arms, the back, neck, jaw, or stomach.
What Does a Mini Heart Attack Feel Like

A mini heart attack, also called a mild heart attack or a non-ST elevation myocardial infarction (NSTEMI), is when there is only partial blockage of the artery, the symptoms don’t last as long as a regular heart attack, and the heart may only suffer minimal damage.
What Is A Good Heart Rate for My Age?
Why Are Diuretics Used in Heart Failure

Diuretics (water pills) help the kidneys get rid of excess water and salt in the body, which makes it easier for the heart to pump. The definition of heart failure means the heart is not pumping as it should to circulate oxygen-rich blood throughout the body. Diuretics are frequently used to treat swelling and water buildup caused by heart failure.
