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!

Non-dihydropyridine calcium channel blockers cause a less-vertical upstroke on this action potential
