Dr Harry Mond visits the early history and recent technological advances in pacing therapies for the treatment of tachyarrhythmias.

Continuing our pacing series, Dr Harry Mond explores pacing and coronary artery disease, alongside the valuable ECG clues for its detection which should not be ignored.

The shock of Ping-Pong in the His-Purkinje system combined with severe digitalis toxicity is the discussion of this rare trace discovered at CardioScan. Medical Director Medicine Dr Harry Mond shares what it reveals and the talks about the changing treatment regimes for such a case.

Cardiac technicians and those that report regularly on Holters may be familiar with cases like this, but the irregularities revealed in this patient are rarely reported on. Dr Harry Mond once again shares insights into another interesting trace, and what’s really going on.

Dr Harry Mond explores rate adaptive pacing where he highlights minute ventilation and closed loop stimulation (CLS) reminding us of the importance of pattern recognition in the prevention of repeating ECGs.

We have previously discussed physiologic ventricular aberration with atrial ectopy or atrial fibrillation with a rapid ventricular response. There is another type of ventricular aberration, which is slower and represents abnormal bundle branch physiology. This is a rate dependent bundle branch block.

This week, Assoc Prof Mond discusses abnormalities commonly missed by physicians when reporting on ECGs, with a focus on reversed arm leads and how to avoid serious misdiagnosis.

Not all ECG recordings are straightforward, as illustrated by this "bizarre" ECG. In this latest edition in our clinical case studies series, our Medical Director Dr Harry Mond explains how he assessed an ECG he was asked to look at, and how eliminated incorrect solutions to the symptoms being presented.

With a pause about twice the cycle length of the R to R intervals and no P, QRS or T waves, this case tackles one of the most difficult explanations in ECG interpretation and demands a revisit to the fundamentals or “footprints” of Wenckebach AV conduction to unravel what's going on.
