Causes Ectopic heartbeats are sometimes seen with: Changes in the blood, such as a low potassium level hypokalemia Decrease in blood supply to the heart When the heart is enlarged or structurally abnormal Ectopic beats may be caused or made worse by smoking, alcohol use , caffeine , stimulant medicines, and some street drugs.

Symptoms Symptoms include: Feeling your heartbeat palpitations Feeling like your heart stopped or skipped a beat Feeling of occasional, forceful beats Note: There may be no symptoms. Exams and Tests A physical exam may show an occasional uneven pulse. Blood pressure is most often normal. If your doctor wants to know more about your heart rhythm, they may order: A monitor that you wear that records and stores your heart rhythm for 24 to 48 hours Holter monitor A recording device that you wear, and records your heart rhythm whenever you feel a skipped beat An echocardiogram may be ordered if your doctor suspects problems with the size or structure of your heart are the cause.

Treatment The following may help reduce ectopic heartbeats for some people: Limiting caffeine, alcohol, and tobacco Regular exercise for people who are inactive Many ectopic heartbeats do not need to be treated. The cause of the heartbeats, if it can be found, may also need to be treated. Outlook Prognosis In some cases, ectopic heartbeats may mean you are at greater risk for serious abnormal heart rhythms, such as ventricular tachycardia.

When to Contact a Medical Professional Call your provider if: You keep feeling the sensation of your heart pounding or racing palpitations. You have palpitations with chest pain or other symptoms. You have this condition and your symptoms get worse or do not improve with treatment. It is important to establish that this is a recurrent, intermittent event rather than continuous rapid palpitations.

Previous studies suggest that up to ventricular ectopic beats in a hour period hour Holter monitor are within normal limits. It is important to be able to reassure patients that a wide range of resting heart rates can be within the normal spectrum. These different devices are also prone to error, particularly during exercise, and can erroneously give very high or very low readings. Sustained rapid palpitations of gradual onset and offset over minutes or longer periods of time may represent sinus tachycardia.

This is also usually benign, particularly at times of anxiety or stress. Less often, sinus tachycardia may signify an underlying disorder such as thyrotoxicosis or anaemia.

Sustained rapid palpitations of sudden onset may be regular or irregular. Patients describe a sudden onset of rapid palpitations that may last from minutes to hours continuously. In the case of atrial fibrillation, this may continue for days or be continuous until treated. In the vast majority of patients, presenting with sudden-onset regular sustained rapid palpitations will signify episodes of supraventricular tachycardia SVT ; in contrast, patients with sinus tachycardia may have a more gradual onset.

Many younger patients, including athletes, may describe a sudden onset of excessive heart rate during exertion that may interfere with their ability to compete.

However, many patients find no particular trigger, and events can occur at rest. While SVT may cause sudden light-headedness at onset, syncope is unusual.

Patients may also complain of chest discomfort or breathlessness during the event. Patients with sustained palpitations and significant associated symptoms eg pre-syncope, breathlessness or chest pain require early referral for evaluation.

Patients presenting with syncope or ongoing chest pain should be transferred to an emergency department by ambulance.

Young patients with rapid palpitations, particularly young women, may be misdiagnosed as having panic attacks. Anxiety and distress may be a normal response to an episode of SVT, and the history will clarify whether the SVT or anxiety occurred first. Patients with SVT can frequently but not universally terminate an event with vagal manoeuvres.

These include the Valsalva technique or cold stimulus to the face. Patients with ventricular tachycardia infrequently present with palpitations as an isolated presenting symptom. The exception to this may be the relatively uncommon idiopathic ventricular tachycardia, particularly when it is recurrent and non-sustained. In most cases, ventricular tachycardia occurs in the context of underlying structural heart disease most commonly prior myocardial infarction , and patients present with features of haemodynamic compromise.

This may include syncope, diaphoresis, chest pain and breathlessness. Such patients would usually be transferred directly to an emergency department when sustained events occur. As structural heart disease may cause palpitations and vice versa , it is important to assess cardiac function in patients presenting with palpitations, as abnormalities can significantly affect management and prognosis. Patients with paroxysmal or persistent atrial fibrillation may present with sustained palpitations.

Patients frequently have associated exertional breathlessness. Syncope due to a rapid ventricular rate in atrial fibrillation is unusual. When patients with paroxysmal atrial fibrillation have syncope, this is frequently due to a significant sinus pause at the time of spontaneous reversion ie tachycardia-bradycardia syndrome.

While chest pain during atrial fibrillation may be solely secondary to a rapid ventricular response rate, if the pain is ischaemic in nature it may reflect underlying coronary artery disease.

Polyuria may be associated with paroxysmal atrial fibrillation because of the associated release of atrial natriuretic peptide. The history should include review of background medical issues that may predispose to arrhythmia eg cardiovascular disease, thyroid illness , psychiatric history, medication history and illicit substances that may contribute to arrhythmia eg stimulant, weight loss medication. Alcohol history is important given the association of alcohol consumption with the risk of atrial fibrillation.

Ectopic heartbeats are changes in a heartbeat that is otherwise normal. These changes lead to extra or skipped heartbeats. There is often not a clear cause for these changes.

They are common. Ectopic beats may be caused or made worse by smoking, alcohol use , caffeine , stimulant medicines, and some street drugs. Ectopic heartbeats are rare in children without heart disease that was present at birth congenital. Most extra heartbeats in children are PACs. These are often benign. In adults, ectopic heartbeats are common. Your health care provider should look into the cause when they are frequent.
