A normal resting heart of an adult beats regularly between 60 and 100 times per minute, according to MedlinePlus. Heart palpitations are characterized by uncomfortable sensations due to irregular beating of the heart. Some individuals experience heart palpitations as a result of an abnormal heart rhythm, while others have no known explanation for their heart palpitations. Treatment may include changing one's lifestyle by diet, minimizing stress and eliminating caffeine and tobacco. Other treatments may include beta blockers.
Abnormal Heart Rhythms
Abnormal heart rhythms are common symptoms of heart palpitations, notes MedlinePlus. A disorder of the heart rate is referred to as arrhythmia. Individuals can have heartbeats that are too rapid, too slow, too early and irregular. When a normal heart responds to a disease state or condition, it may rapidly contract, known as sinus tachycardia. Sinus tachycardia is associated with fever, low blood oxygen, exertion and pain. Low blood oxygen may be due to a lack of magnesium or potassium, which can cause heart palpitations. Heart palpitations may also be due to heart valve disease or heart failure, in which immediate medical attention is necessary.
Dizziness
Dizziness is another symptom associated with heart palpitations. A person can experience periods of dizziness that may lead to a loss of consciousness. Several causes may explain why a person with heart palpitations can experience dizziness or faint. High and low blood pressure can affect the normal functioning of the heart. According to Penn State University Milton S. Hershey Medical Center, if the heart cannot pump enough blood or oxygen through the brain, a person will feel dizzy or weak and pass out. Also according to Penn State, people who are susceptible to dizziness from high blood pressure or cardiac medications should avoid sudden changes of position.
Chest Pain
Chest pain associated with shortness of breath is another symptom of heart palpitations. When a person experiences heart palpitations, it generally means that the heart is not pumping blood normally throughout the body. An insufficient blood supply to the coronary arteries can result in chest pain, also called pressure angina. According to MedlinePlus, angina is characterized by squeezing or tightness in the chest due to a decrease in blood oxygen supply to the heart muscle. Individuals may also feel pressure, heaviness and aching throughout the upper portion of the body. If symptoms persist, sufferers are encouraged to seek medical attention.
