Palpitations
Palpitations
Palpitations occur when a person becomes aware of their heart beating irregularly or abnormally fast. While palpitations are commonly associated with anxiety or stress, they may also be linked to arrhythmias, heart conditions, or external factors like caffeine or medication.
For many people, this can feel alarming, but often the cause is benign. However, in some cases, palpitations may signal an underlying heart condition, and it’s important to consult a cardiologist for an accurate diagnosis.
Palpitations are a common complaint in Australia, affecting people of all ages. Data shows that up to 16% of people will experience heart palpitations at some point in their lives (Evidence-Based Approach to Palpitations, 2021). Although they are often harmless, recurring palpitations warrant investigation, especially since heart disease remains one of Australia’s leading causes of death. According to the Australian Bureau of Statistics (ABS), in 2020, heart disease accounted for approximately 16,000 deaths. This highlights the importance of identifying whether palpitations are a sign of a more serious cardiac issue.

Things you want to know
Palpitations may present as:
- A fluttering or rapid heartbeat
- Skipped heartbeats
- Pounding in the chest
- Sensations of the heart “flip-flopping”
- Discomfort in the chest, throat, or neck. These symptoms may occur during physical activity, rest, or even while lying down.
Palpitations can be triggered by a range of factors, including:
- Anxiety or stress
- Excessive caffeine, alcohol, or nicotine
- Hormonal changes (such as during pregnancy or menopause)
- Certain medications, including stimulants or decongestants
- Arrhythmias (such as atrial fibrillation or ventricular tachycardia)
- Hyperthyroidism
- Low blood sugar levels
- Anemia. In some cases, palpitations occur without a clear cause.
A thorough evaluation by a cardiologist is crucial to determine the cause of palpitations. Diagnostic tests may include:
- Electrocardiogram (ECG): A test that records the electrical activity of the heart.
- Holter Monitor: A portable ECG device worn for 24-48 hours to capture heart activity over time.
- Event Monitor: Similar to a Holter monitor but used for longer periods to catch intermittent palpitations.
- Echocardiogram: An ultrasound of the heart to assess its structure and function.
- Cardiac Stress Test: Measures how the heart performs during physical exertion.
- Blood Tests: To check for hormonal imbalances, thyroid function, and electrolyte levels
While most palpitations are harmless, some can indicate a more serious condition. Complications may include:
- Arrhythmias: Irregular heart rhythms, which can sometimes lead to stroke or heart failure.
- Cardiomyopathy: A disease of the heart muscle that can result in weakened heart function.
- Heart Attack: In rare cases, palpitations may signal an impending heart attack, especially if accompanied by other symptoms such as chest pain or shortness of breath.
Treatment depends on the underlying cause. Options include:
- Lifestyle changes: Reducing caffeine, alcohol, and stress can help alleviate palpitations.
- Medication: Beta-blockers, anti-arrhythmics, or other medications may be prescribed to control irregular heartbeats.
- Ablation Therapy: For patients with arrhythmias, this minimally invasive procedure can help correct the abnormal electrical pathways in the heart.
- Pacemaker: In some cases, a pacemaker may be necessary to regulate the heartbeat.
- Surgery: If palpitations are caused by structural heart issues, surgical intervention may be required.
Commonly Asked Questions
In most cases, palpitations are not dangerous, but they can sometimes indicate a more serious issue, such as an arrhythmia. It is best to consult a cardiologist for an evaluation.
Yes, especially if they occur frequently, last for an extended period, or are accompanied by other symptoms like dizziness, chest pain, or shortness of breath.
Yes, stress is a common trigger for palpitations. Reducing stress through relaxation techniques, mindfulness, or therapy can often alleviate symptoms.
Limiting caffeine, alcohol, and nicotine, managing stress, getting adequate sleep, and staying hydrated are some effective ways to reduce palpitations.
You should seek medical advice if palpitations are frequent, last more than a few minutes, or are associated with dizziness, fainting, chest pain, or difficulty breathing.
By understanding the potential causes and seeking timely care, you can manage palpitations and safeguard your heart health. If you’re experiencing palpitations, contact our clinic today for a comprehensive assessment.
