Another mention of AF in Cycling Weekly this week 11th June 2020. This time as a possible outcome of overindulging in alcohol. I have long believed my own AF was caused mainly by over-exercising and a genetic predisposition; my mother also had AF and was a committed athlete in her youth. I had also considered that alcohol may have been a factor for me (not for my mother, she was a lifelong abstainer)
I was always fond of a drink and there are several ways it may have impacted on my heart. Firstly, I drank too much as a youngster which may have had a toxic effect long term. Later in life, I drank much less, but still more than government guidelines and with some occasional nights of bingeing. Finally, I would often go out for a group ride after several drinks the night before. Although I would not be hung over, I would be slightly dehydrated and my heart trying to push too little volume may have contributed to my ill-health.
After diagnosis, I pretty much cut out alcohol, and my abstinence continued for a long period afterwards because I did not want to further compromise my liver considering that I had large quantities of amiodarone left in my system.
Now, three years post ablation, I have very few drinks. I log every drink that I have and largely remain under the 14 units per week limit, admittedly with a few lapses on special occasions. I also log the number of ectopics or other ECG anomalies I pick up on the Kardia. Luckily everything remains fine.
