About Dr. Gregory Mellor

Dr Greg Mellor is a Consultant Cardiologist and Clinical Director of Heart Rhythm Management at Royal Papworth Hospital, Cambridge. He specialises in the diagnosis and treatment of heart rhythm disorders, combining extensive experience in catheter ablation and cardiac device implantation with nationally recognised expertise in inherited arrhythmia syndromes and the prevention of sudden cardiac death.

After graduating from the University of Cambridge, Dr Mellor completed specialist training in Cambridge before undertaking research into sudden cardiac death at St George's, University of London, where he was awarded an MD (Research). He subsequently completed an advanced fellowship in cardiac electrophysiology at St Paul's Hospital, Vancouver, one of North America's leading centres for inherited arrhythmia syndromes. He has been a consultant at Royal Papworth Hospital since 2017.

Dr Mellor treats the full spectrum of heart rhythm conditions, including atrial fibrillation, supraventricular tachycardia, ventricular arrhythmias, palpitations, blackouts and slow heart rhythms requiring pacemakers. He has particular expertise in inherited heart rhythm disorders, survivors of unexplained cardiac arrest and the assessment of athletes with suspected cardiac conditions. He regularly provides second opinions for complex cases referred from across the UK.

Alongside his clinical practice, Dr Mellor is an active researcher with more than 60 peer-reviewed publications. His research focuses on inherited arrhythmias, unexplained cardiac arrest, cardiac screening and strategies to prevent sudden cardiac death, and he contributes to national and international research collaborations.

Dr Mellor believes that excellent care begins with helping patients understand their condition and the evidence behind the available treatment options. He is committed to clear communication and shared decision-making, ensuring that every patient receives advice tailored to their individual circumstances, priorities and goals.

Very polite reception offering drinks on arrival. Had checks completed before the doctor arrived saving time. The doctor allowed me to explain without any interruptions. Dr Mellor explained in detail the results and answered all my questions at no time did anything feel rushed. Very reassuring team, credit to them all.

I met Dr Mellor on the who explained my current prognosis in respect to very recently experienced Atrial Flutter. He was clear and concise as to what was on offer for me, going forward. Following discussion it was agreed that I would undergo an Ablation under general anaesthetic which was scheduled within two weeks. Dr Mellor met me at Papworth explained again the process I would be going through reassured me and the operation took place as scheduled. Immediately after my recovery Dr Mellor explained exactly what had been undertaken and advised me concisely of future actions I should take in the immediacy and intermediary action to draw final assumptions on my progress. I received excellent care throughout this process from a Dr who is obviously in high demand and a respected professional in his field of work (Heart Electrician).

Doubtless many grateful comments speaking to Dr. Mellor’s expertise and manner will have been left ahead of anything I might write, I shall therefore confine myself to two aspects which, I suspect, may feature less frequently in such reviews. Firstly, I appreciated being given the time to fully explain the background to the consultation; much of what I had to say was peripheral to the clinical matter at hand yet it was important to me to be heard and I was given the space to be fully expressed. Secondly, the letter, subsequently drafted by Dr. Mellor, was free of “back-covering” caveats – in this litigious and defensive world, this was a refreshing change. On both counts and more, thank you.

DR. Mellor, was fantastic from start to finish, I was fully assured throughout the whole process of having an ablation. The good news is i've been afib free since the procedure. would highly recommend Dr Mellor if anyone is thinking of having an ablation done with his expertise at the Royal Papworth. Even the after care he offers is only a phone call away to speak to if you need him. I cant thank you enough for changing my life. Regards Luke
