What is the cause of palpitations in alcoholic cardiomyopathy?

Patient's question:

Our company is quite busy, so we have frequent banquets, drinking beer every night. Recently, for about a week, I've occasionally felt my heart racing and sometimes had difficulty breathing. Yesterday, I had a thorough medical check-up and was diagnosed with alcoholic cardiomyopathy. I've never heard of this condition before. What causes heart palpitations in alcoholic cardiomyopathy?

Doctor's answer:

The patient's recurrence of this condition is due to excessive drinking or chronic overconsumption of alcohol, which leads to repeated alcohol-induced significant harm to the heart muscle, resulting in the recurrence of alcoholic cardiomyopathy. This can then lead to a series of clinical symptoms, including palpitations, arrhythmia, chest tightness, shortness of breath, etc. Once these symptoms reappear, timely treatment is necessary to prevent the condition from worsening.
