Heart palpitations occur when you can feel your own heartbeat as though it is pounding in your chest or fluttering lightly. This may last for a few seconds to several minutes. It may also feel like a skipped or extra heartbeat. In many cases heart palpitations are harmless, but sometimes they could be a sign of a more serious condition. In his latest online article, renowned consultant cardiologist Dr Antonis Pantazis answers your most frequently asked questions about palpitations.

 

What causes heart palpitations?

Heart palpitations can occur for a number of reasons. These include:

  • Psychological triggers such as stress, anxiety, or fear
  • Excessive exercise exerting too much pressure on the heart
  • Certain stimulants such as coffee, tea, and energy drinks. Drugs such as cocaine and amphetamines may also cause heart palpitations
  • Alcohol
  • Smoking
  • Spicy food
  • Some medical conditions such as anaemia, hyperthyroidism, low blood pressure, and fever
  • Medications like diet pills, antihistamines, antidepressants, antibiotics, and asthma inhalers
  • Hormonal changes due to pregnancy, periods, and menopause

 

Heart conditions that can give rise to heart palpitations are:

 

When should you worry about heart palpitations?

Most the time heart palpitations occur only occasionally and for short periods of time. If this is the case, it is unlikely they are the sign of a more serious underlying health condition. However, it is recommendable to get in touch with a GP or specialist if the heart palpitations last a long while, you have a history of heart problems, or you are worried about your heart palpitations.

In some cases, emergency medical attention may be required. It is advisable to call 999 if your heart palpitations are accompanied by shortness of breath, trouble breathing, chest pain, or dizziness.

In order to determine what causes heart palpitations, a doctor will carry out a physical examination and check your medical history, as well as ask questions about diet and lifestyle, and when the heart palpitations generally happen.

There are various tests available in order to make a diagnosis. These include blood tests, electrocardiogram, echocardiogram, X-ray, and Holter monitoring.

 

Treating heart palpitations

Treatment of heart palpitations depends on what causes them. In most cases, as heart palpitations are generally harmless, there may be no need for treatment. If a specific cause cannot be found, the doctor may recommend some lifestyle changes. These might include:

  • Methods to reduce stress and anxiety such as aromatherapy and yoga
  • Cutting down on alcohol, tobacco, caffeine, and illegal drugs
  • Avoiding certain medications such as antihistamines that can have a stimulating effect

Cardiology

Dr Antonis Pantazis is a leading consultant cardiologist who has many years of experience working within the field of cardiomyopathies. He possesses a special interest in the clinical manifestation of the cardiomyopathies (heart muscle condions), their arrhythmogenic manifestation, the risk prevention and the genetic causes of cardiomyopathies.

Additionally, he has a major interest in the cardiac manifestation of neuromuscular conditions, as well as the interaction between sports and cardiac conditions. He also has great experience in pericardial diseases.
 
Dr Pantazis also has an interest in the cardiac imaging diagnostic modalities, and more particularly uses advanced echocardiography imaging in his practice in order to investigate complex heart conditions, including valve diseases and ischaemic heart disease.

Dr Pantazis sees patients who have suspected or confirmed diagnosis of heart muscle and/or pericardial conditions. He also sees patients who may have cardiac symptoms which have not yet been attributed to any pathology. He offers detailed diagnosis, personalised treatment and guides them through interventional management, when required. His practice also covers investigating the diagnosis of the inherited conditions in the family members with genetic and clinical tests.
 
Dr Pantazis has also been leading the Hospital’s programme for the medical (non-invasive) and invasive management of the left ventricular outflow tract obstruction in hypertrophic cardiomyopathy. Left ventricular outflow tract obstruction (LVOTO) is a complex dynamic pathology inside the heart which is responsible for significant symptoms such as breathlessness and chest pain on exertion, palpitations, light-headedness and fainting. Its management requires expertise and patient-specific approach. He runs dedicated clinics for arrhythmogenic cardiomyopathy (ARVC), and cardio-neuromuscular diseases.
 
Dr Pantazis started working as a consultant cardiologist in the cardiomyopathy service of the Heart Hospital, University College London Hospitals NHS Foundation Trust (UCLH) from 2007. He has been the leading cardiologist at UCLH's neuromuscular complex care centre (NMCCC) in The National Hospital for Neurology and Neurosurgery and the academic lead for echocardiography at the Institute for Cardiovascular Science, University College London (UCL).
 
He has been a consultant cardiologist at The Royal Brompton & Harefield NHS Foundation Trust since 2015 and the Trust's clinical lead for cardiomyopathy and inherited cardiovascular conditions. He is also the head of the echocardiography department at North Middlesex Hospital. He has held the position as Consultant Cardiologist at the Royal Brompton Hospital since 2016. 
 
Dr Pantazis is an educational and clinical supervisor to junior doctors. He is responsible for various educational activities in his scientific field, both nationally and internationally.
 
He continues to be involved in research related to phenotype/genotype manifestation of hypertrophic, dilated and arrhythmogenic cardiomyopathy and of left-ventricular non-compaction cardiomyopathy. He has special research interest in the mechanisms and treatment of LVOTO in hypertrophic cardiomyopathy, disease progression and risk in arrhythmogenic (ARVC) cardiomyopathy, the cardiac phenotype in Friedreich's ataxia and the cardiac expression of neuromuscular diseases,. His research has been funded by a number of international grants and his cardiomyopathy-related research outcomes have been published in various peer-reviewed journals.
 
He is also an invited speaker at many national and international meetings. Dr Pantazis contributed to cardiac recommendations on Friedreich's ataxia for Ataxia UK and is also an active supporter of charities, including Cardiomyopathy UK. He is current Chairman of the European Society of Cardiology Working Group on Myocardial and Pericardial Diseases and from this position organises and contributes to international publications and educational activities of high impact.

Additionally to the above services, Dr Pantazis offers second and expert opinions in complex cases on request.
