Abstract

Cardiac amyloidosis typically causes heart failure due to restrictive cardiomyopathy. Along with structural defects, cardiac amyloidosis can also cause conduction abnormalities, especially bradyarrhythmias. When suspected, cardiac amyloidosis can be diagnosed via cardiac imaging modalities or biopsy. However, due to various atypical patient presentations, diagnosing cardiac amyloidosis requires a high index of suspicion and can often be cryptic in nature. We present the rare case of a 71-year-old male who presented with hiccups as his primary symptom and was found to have complete heart block in the setting of cardiac amyloidosis from multiple myeloma in the absence of restrictive cardiomyopathy.
