Swinging beats: transient heart block in cardiac lymphoma

Lyme Carditis with Transient Complete Heart Block

211 Volume XI, no. 2 : May 2010 progressing from high-level AV block through second-degree to first-degree heart block before complete resolution.2 The AV node is most commonly involved, but any level of the conduction system can be affected. Clinical heart failure is observed in approximately 10% of patients, and dilated cardiomyopathy can be a long-term consequence of untreated Lyme carditis....

Primary Cardiac Lymphoma Presenting With Atrioventricular Block

Primary cardiac lymphomas (PCL) are extremely rare. Clinical manifestations may be variable and are attributed to location. Here, we report on a case of PCL presenting with atrioventricular (AV) block. A 55 year-old male had experienced chest discomfort with unexplained dyspnea and night sweating. His initial electrocardiogram (ECG) revealed a first degree AV block. Along with worsening chest d...

Primary Cardiac Lymphoma with Complete Atrioventricular Block

Cardiac symptoms as an initial presentation of malignant lymphoma are rarely seen. We report a 42-year-old male patient of primary cardiac lymphoma originating in the left atrium with episodes of syncope. Complete atrioventricular (AV) block was found by electrocardiography, and the patient was admitted for pacemaker implantation. Before permanent pacemaker implantation, transthoracic echocardi...

Burkitt's lymphoma presenting with heart block.

Transient Cardiac Constriction With Severe Heart Failure

Cardiac constriction is classically understood as a chronic disease which, in most cases, is resolved definitively by surgery.1 Modern imaging techniques have led to a change in this point of view by identifying cases in which this disease can be reversed. A male patient, 73 years of age, a former smoker with dyslipidemia, had been admitted at another centre 2 weeks before with a febrile disord...
