Case
A 61-year-old male was referred with symtoms of exertional dyspnoea and palpitations. He had suffered an anterior myocardial infarction two years previously, but had well preserved systolic left ventricular function. Diastolic function was, however, impaired due to hypertrophic cardiomyopathy which had been diagnosed many years ago. His ECG is shown in figure 1. Serial antiarrhythmic drugs and cardioversions had failed to restore sinus rhythm.
What is the diagnosis? And treatment?
