The ECG shows an example of a patient with bradycardia/tachycardia syndrome (also called sick sinus syndrome). After a further pause of just under 2000 ms, 2 sinus node beats follow, which merge into a sinus tachycardia or atrial tachycardia (heart rate approx.

RBBB is no longer seen after conversion to sinus rhythm — which supports our suspicion that the intermittent RBBB conduction seen every-other-beat during the tachycardia ( in Figure-1 ) was rate-related.

Descriptive analysis of the ECG in today's case reveals a regular, narrow tachycardia at ~130/minute , without clear sign of sinus P waves. But the rate is ~130/minute — which is a bit fast for sinus tachycardia. So IF this is sinus tachycardia with a sinoventricular rhythm — then we have to explain WHY the rate is this fast.
