Gentlemen, with all due respect to your abundant wisdom in subjects of nature and fishing; your attitude toward cardiac rhythm disturbances seems ill-advised. I am not a doctor, but I did work as an ambulance paramedic for many years. I worked on a lot of resuscitation attempts on men who knew something was 'off' in their heartbeat, but did not take the time to get examined by a cardiologist, for what ever reason. Worst case leaves widows, children and friends mourning their passing. Lord forbid that you all might have 'pre-lethal arrhythmias' - but you all cannot know without medical examination and diagnosis. Is it worth the risk to avoid the doctor or the cost?
If you are not a mechanic and your vehicle has an intermittent miss, sputters and misfires - do you take it to a mechanic? The heart's conduction system is electromechanical and biochemical.
Personally, it is not my concern, but as a fellow man (with heart rhythm maintained by a pill) , it is worth the time and effort to get it checked out.
Just my opinion. Take it or leave it. No offense.
