WebMay 2, 2024 · Tachyarrhythmias, defined as abnormal heart rhythms with a ventricular rate of 100 or more beats per minute. From the diagnostic (and therapeutic) perspective, it is helpful to broadly classify tachyarrhythmias into the 4 categories ( figure 1) based on the width, morphology, and regularity of the QRS complex. WebDiagnosis of pacemaker-mediated tachycardia by the pacemaker The anti-PMT intervention is available when the device functions in DDD, VDD, or MVP mode. With MVP mode, the anti-PMT intervention functions only in DDD mode.
