Trivia Quiz: What Do You Know About Cardiac Dysrhythmia?

What do you know about cardiac dysrhythmia? This is a situation in which a person’s heartbeat is either too slow or too fast; at times this condition may be life-threatening and others it may be just normal. How do you know about differentiating the two? Take up the quiz below and get an overview of dysrhythmias. All the best!
