I have been diagnosed with atrial ectopic focus, which disappears at higher rates, occassional non conducted p waves,no runs of SVT/AF/NSVT/VT and no significant pause. also the the TMT result is negative . 2d- echo shows no RWMA and EF = 60%. i am in the indian navy and want to join submarines. so i have to dive in water inside submarines once i go in it. in your medical opinion , do you think its a risk for me to be submerged with the submarine. also how can i improve this condition and is there any medicine which i can pop and my ecg reports comes normal. i am looking for medication that works as quickly as possible.
