3 │ CONCLUSION
A diseased AV conduction system as encountered in our patient may harbor
concealed/decremental conduction and is quite susceptible to
‘long-short’ sequences. This can yield interesting interactions between
conducted and paced rhythms even at relatively slower pacing cycle
lengths. However as showcased here, i) a systematic analysis of device
tracings/ECGs, ii) familiarity with magnet rate responses, and iii)
appreciation of complex electrophysiological mechanisms at play is
quintessential to ‘trouble shoot’ any unusual pacemaker related
responses.
