The term "arrhythmia" refers to any changes from the normal sequence of electrical impulses. The electrical impulses can happen either too fast, too slowly, or too erratically –in turn causing the heart to beat either too fast, too slowly, or too erratically. When the heart does not beat properly, it cannot pump blood effectively. When the heart does not pump blood effectively, the lungs, brain and all other organs cannot work properly and may shut down or be damaged. Heart rhythm problem (heart arrhythmias) occurs when the electrical impulses those coordinate your heartbeats do not work properly, causing your heart to beat too fast, too slow or irregularly. Heart arrhythmias can feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias can cause bothersome — sometimes even life-threatening — signs and symptoms. Heart arrhythmias treatment can often control or eliminate fast, slow or irregular heartbeat. In addition, because troublesome heart arrhythmias can often be made worse — or can even be caused by a weak or damaged heart, so we may or might be able to reduce our arrhythmia risk by adopting a very effective heart-healthy lifestyle.
The term cardiac arrhythmia can cover a very large variety of very different conditions.
The most common of all symptom of an arrhythmia is an awareness of having an abnormal heartbeat, called palpitations. These may be frequent, infrequent, or continuous. Some of these arrhythmias can be harmless (though they might be distracting for patients) but some of them predispose to have an adverse outcome.
Arrhythmias can not cause any signs or symptoms. In fact, our doctor might find we have an arrhythmia before we do, during a routine examination. Noticeable signs and symptoms don't necessarily mean we have a serious problem, however.
A fluttering in our chest
A racing of heartbeat
A slow heartbeat
Pain in chest
Lightheadedness / dizziness
Fainting or nearly fainting
Many things can lead to, or cause, an arrhythmias, including; a heart attack that is occurring right now, scarring of heart tissue from a prior heart attack, changes to our heart's structure, such as from cardiomyopathy, blocked arteries in our heart (coronary artery disease), high blood pressure, overactive thyroid gland (i.e. hyperthyroidism), underactive thyroid gland (i.e. hypothyroidism), smoking, drinking too much alcohol or caffeine, drug abuse, stress, certain medications and supplements, including over the counter cold and allergy, drugs, and nutritional supplements, diabetes, sleep apnea, genetics. So it is better to prevent these things if possible.
