Thank you for providing all the information.
It took me some time to look it up, but I discovered that I had actually undergone an echocardiogram in the past, along with the other examinations. I took a screenshot and attached it as a file. The report is in another language, but I have translated it using online application, and it reads:
'Normal dimensions of the 4 cavities. Normal systolic and diastolic left ventricular function. E/e' 5.4. The various valves are morphologically and functionally normal. No indications of pulmonary hypertension. The hepatic veins are not dilated.'
I really do not want to drink this much, but please, doctor, how is it possible that the arrhythmias and palpitations go away when I drink? I cannot find an explanation for this.
