There are several different kind of arrhythmias. Heart rhythm problems (arrhythmias) occur when the electrical impulses in your heart that coordinate your heartbeats don't function properly, causing your heart to beat too fast, too slow or irregularly.
Arrhythmias are common and usually harmless. Most people have occasional, irregular heartbeats that may feel like a skipped, fluttering or racing heart. However, some heart arrhythmias can be life-threatening.
Arrhythmias may not cause any signs or symptoms. But often, abnormal heart rhythms cause noticeable signs and symptoms, which may include:
A fluttering in your chest
A racing heartbeat
A slow heartbeat
Chest pain
Shortness of breath
Lightheadedness
Dizziness
The best thing you can do is see your doctor about this so he/she can perform tests. Always better to be safe. I have experienced arrythymias and they can be aggravating and worrisome.
Caffeine and certain over the counter medications such as cold medicines, asthma medications, etc. are stimulants and can cause arrhythmias and faster heart rates. If your potassium level is too low, it can also cause arrhythmias. There are many things that can cause arrhythmias.
Again, set up an appointment with your physician to be on the safe side.

ARRHYTHMIA-
An arrhythmia is an abnormality in the heart's rhythm, or heartbeat pattern. The heartbeat can be too slow, too fast, have extra beats, skip a beat, or otherwise beat irregularly.
Arrhythmias are deviations from the normal cadence of the heartbeat, which cause the heart to pump improperly. The normal heartbeat starts in the right atrium, where the heart's natural pacemaker (the sinus node) sends an electrical signal to the center of the heart to the atrioventricular node. The atrioventricular node then sends signals into the main pumping chamber to make the ventricle contract. Arrhythmias occur when the heartbeat starts in a part of the heart other than the sinus node, an abnormal rate or rhythm develops in the sinus node, or a heart conduction "block" prevents the electrical signal from traveling down the normal pathway.
Arrhythmias are characterized by their site of origin: the atria or the ventricles. Supraventricular arrhythmias occur in the upper areas of the heart and are less serious than ventricular arrhythmias. Ventricular fibrillation is the most serious arrhythmia and IS FATAL UNLESS MEDICAL HELP IS IMMEDIATE
Arrhythmias can be prevented by managing stress, controlling anxiety, stress and avoiding caffeine, alcohol, decongestants, cocaine, caffeine diet pills, chewing tobacco and cigarettes apart from heart disease.
It is also VERY ESSENTIAL you have regular medical check-up and medicines as prescribed by your Cardiologist.-

A heart rate faster than 100 beats/minute is considered tachycardia. This number varies with age, as the heartbeat of a younger person is naturally faster than that of an older person's. With exercise the sinus node increases its rate of electrical activity to accelerate the heart rate. The normal fast rate that develops is called sinus tachycardia. Arrhythmiae that are due to fast, abnormal electrical activity can cause tachycardias that are dangerous. If the ventricles of the heart experience one of these tachycardias for a long period of time, there can be deleterious effects. Individuals may sense a tachycardia as a pounding sensation of the heart, known as palpitations. If a tachycardia lowers blood pressure it may cause lightheadedness or dizziness, or even fainting (syncope). If the tachycardia is too fast, the pump function of the heart is impeded, which may lead to sudden death.
Most tachycardias are not dangerous. Anything that increases adrenaline or its effects on the heart will increase the heart rate and potentially cause palpitations or tachycardias. Causes include stress, ingested or injected substances (ie: caffeine, alcohol—see Holiday heart syndrome), and an overactive thyroid gland (hyperthyroidism). Individuals who have a tachycardia are often advised to limit or remove exposure to any causative agent. However, these causative agents are not the only contributors to tachycardias and their prevalence has not been evaluated statistically.
A slow rhythm, known as bradycardia (less than 60 beats/min), is usually not life threatening, but may cause symptoms. When it causes symptoms implantation of a permanent pacemaker may be needed. Either dysrhythmia requires medical attention to evaluate the risks associated with the arrhythmia.

I assume you are talking about heart arrhythmia. it means an irregular heartbeat. There are forms that are dangerous, and others that are not. You really need to get a medical workup to know the difference.
I have had occasional heart arrhythmias all of my life (I'm 62), and the tests I've had show they are not dangerous, so I don't worry about it.
One thing that I've read, and it seems to work for me, is that coughing when you feel your heart beat getting irregular helps. It has to do with the action of your diaphragm stimulating your heart.
But please, don't just treat yourself. Get checked out. If there is a problem, you can work on it, and if not, you can relax.

i have irregular sinus tachycardia...which means i experirnce rapid heart beats(up tp 220 a min) and i still dont know if its dangerouse? the doctors havent helped in answering and a i did have ablashia(tube in thigh up to hart) and nothing........i have giving up on worring in 2000 i had a "mild" heart attack and still nothing fromthe doc,,,,so good luck finding out. i work out 5 days a week running 5 miles a day-now and its better so all i can tell you is take care, its scarey, but so is the docotors-they are clueless on this..........

No its not dangerous in some situations.I assume yours are not dangerous because they are returning and nothing happened before. To be on a safe side talk to a doc. and let them run testes
