Arrhythmias (irregular heartbeats) are common in people with cardiac amyloidosis. The most frequent type is atrial fibrillation (AFib), which can cause rapid heartbeat sensations. These rhythm changes can occur because amyloid deposits may disrupt the heart's electrical system, and when blood backs up, it increases pressure in the heart. While it's good that your husband has undergone monitoring and testing, intermittent symptoms can be challenging to catch during testing periods. Since this is affecting his quality of life, particularly at night, it's worth continuing to document when these episodes occur and what might trigger them. Consider keeping a detailed log of when the rapid heartbeat happens, including time of day, position, and any other symptoms, to help doctors better understand the pattern.
