In this module, we will discuss an overview of palpitations. We will discuss why and when palpitations occur and why they occur more frequently as one gets older. You will learn when palpitations are benign and when they are worrisome and may be caused by a life-threatening condition. You will learn what questions to ask and which symptoms are benign or suspicious. Lastly, we will review a number of cases of arrhythmias including patients with polymorphic and monomorphic ventricular tachycardia, atrial fibrillation, and atrial flutter, and you will learn in which patients these arrhythmias are more likely to occur.
