Ventricular tachycardia happens when the ventricles (the lower chambers) beat too fast, and it’s very dangerous. Common types of supraventricular tachycardia are atrial flutter and atrial fibrillation External Link. Supraventricular tachycardia is not usually life-threatening. The two main types of tachycardia are supraventricular tachycardia (problem with the upper chambers of the heart) and ventricular tachycardia (problem with the lower chambers). Some forms of tachycardia are easily treated and not serious, but others can be life-threatening. Tachycardia is when your heart beats too fast, generally more than 100 beats per minute. Other abnormal rhythms are more serious and can be life-threatening if left untreated.Ībnormal rhythms are classified by their rate and rhythm: fast heartbeat (tachycardia), slow heartbeat (bradycardia) or irregular heartbeat. Some may cause your heart to skip or add a beat now and again but will usually have no effect on your health or ability to lead a normal life. There are many kinds of abnormal heart rhythms. See your doctor if you have more frequent or consistent palpitations, which may be associated with a serious abnormal heart rhythm. Palpitations may have no obvious cause, but can be triggered by:Īn occasional palpitation that does not affect your general health is not usually something to worry about. Almost everyone has palpitations at some time in their life. It may feel like your heart is racing, thumping, fluttering, pounding or skipping beats. Palpitations are a sensation or awareness of your heart beating. Changes in your heart’s electrical system can cause abnormal heart rhythms External Link, also called ‘arrhythmias’. Sometimes, your heart’s electrical system may not work properly because of heart disease, some medicines, or sometimes for no known reason. In a healthy heart, regular electrical signals cause the heart to contract and relax in a steady rhythm of 60 to 100 beats per minute. Normally, the pumping action of your heart (your heartbeat) is controlled by your heart’s electrical system.

If you frequently experience heart palpitations, there is no reason not to see your doctor. Heart health is an important aspect of general healthcare. Benign palpitations, on the other hand, speed up but keep a steady pace before slowing down to normal. Individuals with thyroid conditions may be at a greater risk of AFib, as are individuals over the age of 65. Also, benign palpitations typically come and go more quickly than those attributed to electrical misconduct in the heart. Heart palpitations could coincide with sweating and nausea, two other symptoms of anxiety and stress. If you are in a stressful situation or time of life, there is a good chance that palpitations are the result of the body releasing stress hormones like cortisol. So how might you be able to notice the difference? A few details to look for include: In fact, palpitations, or a racing heart, is a prime symptom of atrial fibrillation. What makes discernment difficult is that benign palpitations mimic the symptoms of AFib. Blood then pools in these upper chambers rather than moving on to the lower chambers as it should. When this misfire occurs, the upper chambers of the heartbeat too quickly and at an abnormal pace. This event occurs as a result if a misfire of electrical signals to the heart. Because a lot of us carry unmanaged stress around like it’s necessary, palpitations can send the heart fluttering at any moment, without a moment’s notice. Atrial fibrillation, aka AFib, is different. Heart palpitations are perceived as a normal event when the body or mind is experiencing some stress. However, it is important to be able to differentiate between the “average” palpitation and a potentially serious problem. In many cases, this sensation may be normal. Arrhythmias may also occur for seemingly no good reason at all. This may occur while engaging in some physical activity, like working out or working in the yard. Most adults have felt it a time or two: that thump or fluttering sensation in the chest.
