Missing a beat could be ventricular ectopics which would go hand in hand with feeling a 'lurch'.
A ventricular ectopic is a missed beat followed by an extra strong one which feels like a thump.
It's harmless but disconcerting. Every third beat is towards the upper end of the scale but still harmless.
Trigger factors are normally stress, tiredness, caffeine and alcohol with alcohol normally being the biggest.
Obv don't accept the word of some internet stranger and get checked out. Not least because the sudden increase in HR would not be explained by ectopics.
