Feeling your heart palpitate can be a frightening experience. If your heart begins to palpitate after you've eaten a food that contains gluten, you may be having an allergic reaction to the gluten. Unlike mild allergy symptoms, heart palpitations are a sign of a serious complication called anaphylaxis.

With congestive heart failure -- commonly referred to as simply heart failure -- your heart cannot adequately pump blood throughout your body. More than 2.5 million women in the United States have heart failure, according to 2015 American Heart Association statistics.

Congestive heart failure, CHF, is a condition in which the pumping action of your heart is compromised and the heart fails to pump as efficiently as it should. Your tissues and organs rely on the blood pumped from the heart for the delivery of oxygen and nutrients, hence CHF affects the entire body.

Congestive heart failure effects about 5 million people in the United States and is responsible for more than 300,000 deaths annually, according to the website MedlinePlus.

Dieting is a serious endeavor that requires conscientious effort and dedication. Just like any other challenge you face, there is a right way to approach a diet and a wrong way. Unfortunately, improper dieting can cause permanent damage to your physical and mental health and can even endanger your life.

Heart rhythm is controlled by the sinoatrial node and the atrioventricular node, which reside in the heart. These send out electrical impulses that cause the heart to contract at about 60 to 80 beats per minute. A heart palpitation is an abnormal heart beat that makes you aware of the beating.

The American Academy of Family Physicians points out that while most times an increased or abnormal heartbeat is not a serious symptom, heart palpitations can be a sign of a life-threatening cardiac arrhythmia.

Heart palpitations, a type of cardiac arrhythmia, have been described as an electrical storm in your heart. Heart palpitations can range from mild and sporadic occurrences to life-threatening emergencies.

Heart palpitations are irregular heartbeats that can cause your heart to race, flutter, pound, skip beats or briefly stop. A variety of factors can trigger heart palpatations, such as anxiety, stress, emotional distress, panic, heart problems, an overactive thyroid, nicotine, alcohol and caffeine.

Congestive heart failure occurs when the heart fails to efficiently pump a sufficient amount of blood to the body's organs and tissues. As fluid pools in areas such as the lungs, they become congested. Also called CHF, congestive heart failure can come on suddenly or develop gradually.

The mineral iron plays an important role in oxygen transport and helps regulate cell growth and division. According to the Office of Dietary Supplements, approximately two-thirds of the iron in the body is found in red blood cells.

The entire body relies upon the heart's ability to pump that's blood rich in nutrients and oxygen. When the heart is damaged by high blood pressure, heart attack, infections or other diseases, other organs begin to show symptoms of damage.
