Lyme Carditis: An Interesting Trip to Third-Degree Heart Block and Back
Case Reports in Cardiology, 2016
Carditis is an uncommon presentation of the early disseminated phase of Lyme disease. We present the case of a young female who presented with erythema migrans and was found to have first-degree heart block which progressed to complete heart block within hours. After receiving ceftriaxone, there was complete resolution of the heart block in sequential fashion. Our case illustrates the importance of early recognition and anticipation of progressive cardiac conduction abnormalities in patients presenting with Lyme disease.

Lyme disease may present with a variety of cardiac manifestations ranging from first degree to third degree heart block. Cardiac involvement with Lyme disease may be asymptomatic, or symptomatic. Atrioventrical conduction abnormalities are the most common manifestation of Lyme carditis. Less common, are alternating right bundle branch block (RBBB) and left bundle branch block (LBBB). We present an interesting case of a young male whose main manifestation of Lyme carditis was isolated LBBB. He also had mild Lyme myocarditis. The patient was successfully treated with oral doxycycline, and his isolated LBBB and myocarditis rapidly resolved.

Lyme carditis is a known cause of atrioventricular block and in most cases, atrioventricular block is reversible with appropriate antibiotic treatment. The diagnosis can be challenging if the disease is either not suspected, or if the initial cutaneous manifestation of erythema migrans is missed. It is important to diagnose Lyme carditis as the cause of complete heart block if unnecessary pacemaker implantation is to be avoided. We present a 43-year-old male who presented with complete heart block and also illsustained ventricular tachycardia due to Lyme carditis that reversed completely with antibiotic therapy.
Lyme carditis: complete atrioventricular dissociation with need for temporary pacing
Hellenic journal of cardiology : HJC = Hellēnikē kardiologikē epitheōrēsē
Lyme borreliosis is a tick-borne disease. Cardiac manifestations of the disease are extremely rare. We report a case of Lyme carditis in an otherwise healthy male, who presented to the Accident & Emergency Department with chest pain, dizziness and generally symptoms indicating ischaemic heart disease. This patient, without documented history of Lyme disease, acutely developed third-degree atrioventricular block, which required placement of a transvenous pacemaker and resolved when the patient was administered doxycycline.
Lyme carditis: Sequential electrocardiographic changes in response to antibiotic therapy
International Journal of Cardiology, 2009
Lyme disease is a tick-borne spirochetal infection that may involve heart. The cardiac manifestations of Lyme disease including varying degrees of atrioventricular heart block occur within weeks to months of the infecting tick bite. This report describes a 43 year-old man with Lyme carditis who presented with complete heart block. The heart block resolved with ceftriaxone therapy. Lyme carditis should be considered in the differential diagnosis in patients who present with new onset advanced heart block.
First reported case of Lyme carditis in Southwest Michigan
Spartan medical research journal, 2017
Lyme disease is the most common tick-borne infection found in the eastern United States. In recent years, it has become an emergent Michigan public health concern. Lyme carditis is a recognized rare complication which is classically characterized by rapidly fluctuating degrees of heart block. In severe cases, or if inappropriately treated, Lyme carditis can also result in profound bradycardia, perimyocarditis, and sudden cardiac death. This report describes the first documented case of third degree heart block associated with Lyme carditis to occur in Michigan. This is a retrospective case report of a patient evaluated and treated for Lyme carditis in Southwest Michigan in July, 2016. All information was obtained from either the patient or his electronic medical record. Despite initial misdiagnosis and inappropriate management, this patient ultimately received more appropriate medical therapy within 24 hours of first presentation. After eight days of high dose intravenous Ceftriaxone and supportive care, and more than two weeks of oral Doxycycline, the patient's symptoms resolved and the disease was treated to resolution. Neither permanent nor temporary pacing was needed during/after the course of treatment. When correctly identified, Lyme disease and Lyme carditis can be easily treated. Although this patient's history was without reported tick bite or exposure to a known host for Lyme disease, the authors believe that the patient's history and physical exam was definitive enough to warrant the start of IV therapy with telemetry monitoring upon first presentation. The fact that the condition was not first diagnosed by providers indicates a potential gap in medical knowledge and awareness that should be addressed in clinical practice. The authors consider this case a harbinger of the emerging disease of Lyme carditis. Physical exam and EKG findings should guide clinicians' therapeutic approaches. Although treatment with appropriate antibiotics is typically curative, therapeutic delays can lead to deadly results.
Cardiac implications of Lyme disease, diagnosis and therapeutic approach
International Journal of Cardiology, 2008
Lyme is a tick-borne disease. The genetic diversity of Borreliae its distribution worldwide and its epidemiology have been related to different clinical manifestations. Carditis is a rare manifestation of Lyme disease. The commonest abnormality is atrioventricular block of various degrees, though other rhythm abnormalities have been reported. Pericarditis, myocarditis, cardiomyopathy and degenerative valvular disease have been associated with B. burgdorferi. Temporary pacing might be required in unstable patients. The majority of the conduction disturbances have a benign prognosis, if the infectious agent is identified and treated appropriately.
MMWR. Morbidity and mortality weekly report, 2014
On December 13, 2013, MMWR published a report describing three cases of sudden cardiac death associated with Lyme carditis. State public health departments and CDC conducted a follow-up investigation to determine 1) whether carditis was disproportionately common among certain demographic groups of patients diagnosed with Lyme disease, 2) the frequency of death among patients diagnosed with Lyme disease and Lyme carditis, and 3) whether any additional deaths potentially attributable to Lyme carditis could be identified. Lyme disease cases are reported to CDC through the Nationally Notifiable Disease Surveillance System; reporting of clinical features, including Lyme carditis, is optional. For surveillance purposes, Lyme carditis is defined as acute second-degree or third-degree atrioventricular conduction block accompanying a diagnosis of Lyme disease. During 2001-2010, a total of 256,373 Lyme disease case reports were submitted to CDC, of which 174,385 (68%) included clinical inform...
