Thank you very much for posting this question in HCM
Let me tell you that a given medical problem can be due to various causes and the primary aim of the attending doctor is to find out the exact cause and deal with it accordingly rather than simple assumption in the modern era of medicine.
Similarly the causes of dizziness
are many. For example some can become dizzy with heart problem, some body can be with neurological problem and even some body can be dizzy after diarrhea
. In addition there are other causes too.
Back to your problem, the symptoms that you have, i mean the irregular hear beat, particularly slow as well as very fast heart rate
can make you dizzy and weak. The simplest test which will identify this problem is ECG. It will tell is it faster than normal or slower than normal and we can deal accordingly. All the symptoms that you have described, particularly when you tell that flu
is going on, some viral infection can also have the similar presentation. Another cause for all your symptoms could be thyroid
problem. I strongly advise you to go for an urgent check up with a physician who will approach the way i have described. How ever you donot have to worry. Your problems need urgent medical attention
Hope this will help you
Get well soon
