Detailed Answer:
Hello!
Welcome and thank you for asking on HCM!
Regarding your concern, I would explain that it is true that those episodes of arrhythmia are triggered by physical activities and coffee intake.
Other possible causes to consider would be : cardiac ischemia, thyroid dysfunction, anemia, electrolyte imbalance, QT prolongation syndrome, etc.
As your symptoms keep occurring during the night, this could be related to gastroesophageal reflux or sleep apnea.
For this reason, I would first recommend trying an antiacid or PPI ( omeprazole, etc.). It would help improve your situation in case of acid reflux.
Otherwise, I wound recommend performing a polysomnogram, to investigate for sleep apnea.
You should discuss with your doctor on the above issues.
Hope to have been helpful!
Kind regards,
