Sinus node dysfunction: Epidemiology, etiology, and natural history. In: Clinical Arrhythmology and Electrophysiology: A Companion to Braunwald's Heart Disease. The heart rate alternates between unusually slow and fast rhythms, often with a long pause between heartbeats. The heart rate is within regular range at rest but doesn't increase as much as it should with physical activity. Signals to the upper heart chambers are slowed or blocked, causing pauses or skipped beats. Signals from the sinus node pause, causing skipped beats. The sinus node produces a slow heartbeat. Neuromuscular diseases, such as muscular dystrophy.
Sick sinus syndrome is relatively uncommon, but the risk of developing it increases with age.Ĭauses of sick sinus node syndrome can include: The heartbeat can be too fast, too slow, interrupted by long pauses - or an alternating combination of these rhythm issues. In sick sinus syndrome, the electrical signals are irregularly paced. The pace changes depending on activity, emotions and other factors. Typically, the sinus node creates a steady pace of electrical impulses. From the sinus node, electrical signals travel across the atria to the ventricles, causing them to contract and pump blood to the lungs and body. However in many cases, palpitations are NOT caused by any problem with your heart.This natural pacemaker produces electrical signals that trigger each heartbeat. These wires measure the electrical signals in your heart and can determine where any abnormal electrical signals are coming from.Īll these tests are to make sure there is no abnormality in your heart causing the heart palpitations. Small wires (electrodes) are inserted into your heart via one of your veins.
You will be asked to make a note of when you get the palpitations. Ambulatory ECG: this is an ECG that records your heart as you carry on your normal life over 24 or 48 hours.It also looks for underlying or previous heart disease. Electrocardiogram (ECG) to record the electrical impulses of your heart to check whether the heart rate is regular, and of normal rate.Blood tests to check for anaemia and an overactive thyroid gland.Initial investigations for heart palpitations include: Your doctor will take your pulse and blood pressure, listen to your heart and order further tests as appropriate. You are likely to be asked about your intake of the substances mentioned above and the circumstances in which the heart palpitations occur. This list does not include all the possible causes of heart palpitations but lists some of the more common causes, including: Or you can follow the steps shown on the British Heart Foundation website, given in 'Further reading & references' at the end of this leaflet.

Your practice nurse can show you how to take your own pulse. This information can help identify the cause of the palpitations. That is, how many beats per minute also, if your pulse felt regular or irregular. In particular it may be useful for your doctor to know how fast your pulse was during the episode. If you have an episode of heart palpitations it can be useful to check your pulse. Keep a diary of when they happen and how long they last, as this information will help your GP. If the palpitations do not make you feel unwell, and settle on their own, you should see your GP.
