Ventricular tachycardia due to a transvenous catheter pacemaker.
Ventricular tachycardia may be caused by temporary cardiac pacing, especially when there is acute inferior myocardial infarction with significant right ventricular extension. Correction of hypoxemia, electrolyte imbalance, and drug excess, and the use of a unipolar lead with proper sensing and pacing settings may prevent this complication.
