title: A 38-Year-Old Man With Obesity, Intermittent Tachycardia, and One Episode of Syncope.
abstract: A 38-year-old man with history of diabetes, hypertension, hyperlipidemia, and obesity was referred to the electrophysiology clinic for evaluation of infrequent palpitations and remote history of syncope. The patient described a sensation of racing of the heart, which lasted about 30 min to 1 h and occurred several times over the past year. This was associated with a sense of anxiety and shortness of breath and appeared to resolve spontaneously. The patient also experienced one episode of syncope in the past while enjoying a barbecue on a hot summer day. He did not recall if this episode was accompanied by palpitations, however, the previously mentioned symptoms prompted the consultation. Upon further questioning the patient also reported experiencing fatigue. He stated that he noted decreased energy and frequent daytime sleepiness.
