Just as a follow up for those who may be similarly affected in the future.
Visited a CAA approved cardiologist yesterday for an echo and further ECG. All completely normal thank goodness. ECG once again showed large voltages in V5, V6 which he put down to being slim and fit......basically not alot of fat on my upper torso so ECG was picking up large voltages.
Apparently the auto ECG assessment is renowned for throwing up LVH irregularities quite regularly.
