Video Transcription

Video Summary

In this video, the speaker discusses electrogram interpretation in devices. They highlight the importance of differentiating between SVT (supraventricular tachycardia) and VT (ventricular tachycardia) using criteria such as local electrogram morphology, VV stability, response to ATP or shock, and the presence of atrial far-field signal. The speaker presents examples of complex electrograms and asks the audience to interpret them. They also discuss the educational gap in electrogram interpretation and the need for better education in this area. The video also covers topics like noise in electrograms, competitive HL pacing, and the consequences of competitive pacing. The speaker points out that RNR-VS (repetitive non-reentrant ventricular HL synchrony) and PMT (pacemaker-mediated tachycardia) are two sides of the same problem and that curing PMT may not solve the issue. The video concludes with a multiple choice question and a humorous reference to the audience's understanding of the topic.
