###Human: I had sudden cardiac arrest with hypokalemia. Please interpret my ECG. ###Assistant: Hello. I am sorry to hear about your health condition. This is extremely strange that at 25 years of age you suffered a cardiac arrest. Have you had problems with hypokalaemia before the attack? Where you on diuretics? Do you have history of similar problem in your family? Have you always suffered low blood pressure? Or was it after the attack?
