Underlying rhythm is AF. There are 2 PVCs with a lbbb morphology. In V1-V3 there are 2 complexes with typical RBBB morphology- preceded by a long-short cycle and there are other RR intervals that are shorter without a RBBB. Hence Ashman effect and not rate related RBBB

ECG 1-sinus tachy rate 105 bpm, biatrial hypertrophy and PR interval 0.20 sec. ECG 2 sinus tachy at rate 130 bpm PR interval 0.32 sec- longer despite faster rate. Hence dual AV nodal pathways.

Rhythm is regularly irregular with a sinus complex followed by an early qrs complex that has a negative p wave in leads 2 and aVF. These are PACs in a bigeminal pattern. At end is NSR.

Coarse AF (atrial waves are irreg in morphology, amplitude and intervals) with QRS complexes at a regular rate, ie regularized AF which is due to complete heart block. The escape rhythm is junctional and hence the CHB is due to AV nodal block.

Narrow complex regular Supravent tachy arrhythmia at a rate of 270 bpm. The only supravent rhythm at this rate is atrial flutter with 1:1 conduction. Also noted is electrical or QRS alternans. The j point depression and st depression may be due the superimposed flutter wave.

short rp supraventricular tachycardia. This is not sinus but may be junctional or atrial. Since it terminates with a non conducted p wave this indicates that this is a junctional tachycardia. Hence this is a typical avnrt.

Biventricular pacemaker. It is tracking an atrial tachycardia that has a rate of 220 bpm. Pacemaker function is A sensed V paced but as atrial rate is greater than upper rate limit of pacemaker only every other p wave is sensed and hence vent pacing rate is 110 bpm.

At end of the ecg there is NSR with 2:1 block (which can be either mobitz type 1 or type 2. QRS has lbbb. At beginning there is chb with an escape ventricular rhythm. Hence the 2:1 av block is mobitz type 2.
