About Dr Mellor
Dr. Mellor graduated from the University of Cambridge in 2004 and completed the majority of his medical training in East Anglia. He undertook a clinical research fellowship, funded by Cardiac Risk in the Young, at St. George’s, University of London in the field of sudden cardiac death and exercise which led to the award of an MD(Res) in 2017. He also completed a clinical fellowship in cardiac electrophysiology with a focus on inherited arrhythmia syndromes at St. Paul’s hospital Vancouver.
Dr. Mellor treats a wide range of heart rhythm disorders with particular interests in inherited arrhythmia syndromes, unexplained cardiac arrest and arrhythmias in athletes.
