An unusual cause of a complete heart block in a young healthy man!

Abstract: Acute myocarditis represents a challenging diagnosis as there is no pathognomonic clinical presentation. It is rare to see heart block as the first-and-only presentation of infectious myocarditis. We report the case of a young healthy patient who presented with syncope secondary to a complete heart block. It was caused by acute presumed viral myocarditis. The diagnosis was confirmed with cardiac magnetic resonance imaging. With close monitoring, the EKG abnormalities resolved over the following 5 days. In this… Show more

“…However, as in our case, symptomatic bradycardia and refractory or irreversible causes of heart block require a permanent, implantable pacemaker. 9 Such patients should be monitored outpatient as this subacute or refractory infection can progress to nasopharyngeal carcinoma or Burkitt lymphoma. They should be monitored for fever, malaise, hepatosplenomegaly, coagulopathy, cytopenia, and unintentional weight loss.…”

“…Apart from the higher incidence of AVB in these conditions, another early study noted that a pacemaker was required in 60% of cases with giant cell myocarditis, while only 8.3% of AVB in lymphocytic myocarditis required a pacemaker [ 16 ]. Permanent pacemaker insertion is rarely required in lymphocytic myocarditis with only a handful of cases reported [ 17 19 ]. A permanent pacemaker was inserted on presentation in our case due to several reasons.…”
