Hi doctor,

I have attached the smartwatch ECG readings. I have been diagnosed with AL cardiac amyloidosis and have Mayo Stage IIIa heart failure. I am especially interested in the "peaks" between 6s and 7s, and between 16s and 17s, as they correspond with an odd sensation, which I would characterize as a flutter or the like.



Welcome to icliniq.com.

I understand your concern regarding ECG (electrocardiogram) changes. I have gone through your ECG readings (attachments are hidden to protect the patient's identity). Grossly, I can see premature ventricular complexes here, which can be explained by underlying amyloidosis. Between 7 and 8 seconds and 16 and 17 seconds, the huge complexes that you see are premature ventricular complexes only, and then there is a pause after that. I cannot see any flutter waves here. I would suggest a 24-hour Holter monitoring so that the frequency of these complexes can be determined, and if required, rate control medications can be given. Hope this has answered your query. Thanks and regards.

Hello doctor,

Thank you for the swift and thoughtful answer.
