Atrial fibrillation is the medical term that is used to describe an irregular heartbeat, and can lead to stroke if not diagnosed and treated appropriately.

 

In our latest article, Dr Mokhtar Ibrahim, a highly established and trusted consultant cardiologist, advises patients when they should seek medical attention for atrial fibrillation, and reveals how it is diagnosed and treated.

What is atrial fibrillation, and how will I know I have it?

Atrial fibrillation is an abnormal heart rhythm. It is the most common heart rhythm disorder in adults, affecting about one per cent of the general population. The heart beats faster than normal, doing so quite irregularly.

 

Some people with atrial fibrillation are completely asymptomatic, and is diagnosed accidentally during a routine health check. A blood pressure machine can identify if you have an irregular heart rhythm. Other people also present with palpitations, shortness of breath, dizziness, feeling faint, and stroke. Atrial fibrillation is the most common cause of stroke. 

 

When should I get seen for atrial fibrillation?

Any patient who is suspected of having atrial fibrillation should be seen by a cardiologist to have a full assessment. The first step is initial screening, including blood tests, and an echocardiogram for the heart.

 

Then, if the patient is diagnosed with atrial fibrillation, they are seen periodically by their GP and cardiologist. The cardiologist will offer the patient appropriate treatment options.

 

How is atrial fibrillation diagnosed?

Atrial fibrillation was traditionally diagnosed via an electrocardiogram (ECG). People who have infrequent symptoms can be given a portable monitor. Interestingly, the FDA have recently approved apple watches as effective portable monitors to be able to diagnose atrial fibrillation.

 

For people who do not have apple watches or technology that can diagnose atrial fibrillation, we can also implant a monitor under the skin that can keep recording and monitoring the heart rate and rhythm for as long as up to five years.

 

Should it be treated immediately? What happens if it is left untreated?

If a person with atrial fibrillation is above the age of 65, has hypertension, diabetes, heart failure, and has had a previous stroke, individuals need to be provided with blood thinners immediately on a life-long basis. A person could suffer from stroke if their atrial fibrillation is not treated adequately.

 

If the patient is completely asymptomatic, we might just treat atrial fibrillation with blood thinners and that will be enough. If patients have a significant number of symptoms, we can provide the patient with tablets to slow down the heart rate.

 

What should I do if I suffer from atrial fibrillation?

If patients suspect that they may be suffering from atrial fibrillation, they should immediately seek medical advice from an experienced cardiologist. In this consultation, the patient will be examined and their risk factors will be assessed.

Cardiology

Dr Mokhtar Ibrahim is an internationally trained consultant cardiologist and electrophysiologist practising in Leicester. He specialises in many cardiac conditions, like syncope and atrial fibrillation, and treatments such as pacemakers, device implants, and ablation. In addition, Dr Ibrahim has an expertise in sports cardiology.

In 2005, Dr Ibrahim received his medical qualification from Ain Shams University in Egypt. He continued to receive speciality training in cardiology until 2014 when he was appointed as a consultant cardiologist at the university hospital in Cairo. In 2016, Dr Ibrahim relocated to the UK where he subsequently undertook a two year advanced clinical fellowship in cardiac electrophysiology and devices at the Royal Brompton and Harefield Hospital.

As of 2019, Dr Ibrahim has been working as one of the few cardiologists in the UK who have European accreditation in both cardiac electrophysiology and devices. He achieved this by completing the required exams and the required number of cases by the European Heart Rhythm Association. This expertise allows him to perform more than 250 procedures per year including (but not limited to): radiofrequency ablation procedures for different cardiac arrhythmias; device implantation such as pacemakers, cardiac resynchronization therapy and implantable cardiac defibrillator (ICD); and HIS-bundle pacing, which is a novel technology in permanent cardiac pacing for heart failure.

Dr Ibrahim held the position as co-principal investigator on two research studies, and continues to do research when possible. In addition, he has had multiple published works in peer-reviewed journals. Dr Ibrahim has also presented at meetings in Egypt, the UK, and internationally. Over the years, he has regularly taken continuous professional development courses in topics such as cardiac specialities and management and leadership skills. Dr Ibrahim has taught previously at Ain Shams University Hospitals, and he continues to hold teaching posts for future cardiology surgeons at Imperial College London.
