Hasan ECG due to palpitations, don't understand results :(

[Jakemcc]

Hi all, firstly thanks in advance for reading. Easiest way to describe this is roughly for 2 months I notice my heart feels like it beats really heavily or skips a beat when I'm relaxing or sitting still. I've had a resting ecg and 24 hour ECG. The resting showed the interval of blood leaving my heart I believe was 0.21ms where the recommended bracket is something like 0.10-0.20.
I have a pic of my 24 hour ECG... Can you all see if this looks suspicious as my local GP says it's nothing to worry about...?
