Determination of ventricular vulnerable period and ventricular fibrillation threshold by use of T-wave shocks in patients undergoing implantation of cardioverter/defibrillators. Hou CJ1, Chang-Sing P, Flynn E, Martinez L, Peterson J, Ottoboni LK, Liem LB, Sung RJ.
a short period in the cardiac cycle during which activation may result in an ectopic beat. The ventricular vulnerable period.
Following ligation of left anterior descending coronary artery in dogs, low energy shocks delivered in the ventricular vulnerable period result in ventricular tachycardia—VT(?p). These disorders degenerate to ventricular fibrillation. VT(?p) can be reverted to sinus rhythm with transthoracic shocks of less than 1 Wsec. Within 7 days after infarction, VT(?p) can no longer be evoked. Similar arrhythmias have been noted in men with acute myocardial infarction.
Clinical and Electrophysiological Significance of Induction of Morphologically Different Ventricular Fibrillation During Ventricular Vulnerable Period.
p. m. An atrial-based lower rate timing during the DDD pacing also accounted for the ‘long’ part of the short–long–short sequence. Thus, decreasing the upper limit of the pacing rate or shortening the paced AV interval would be beneficial in treating those pacing-induced VTs. The prolongation of the ventricular blanking period to prevent the detection of far-field activation and the following VSP would be the another way to treat patients, but it also increases the risk of ventricular pacing in the vulnerable period.
